SWYK: Solving Algebraic Equations (tomorrow)

I just wanted to send out another (more detailed) reminder of tomorrow’s math assessment on Solving Algebraic Equations. Topics include solving one- and two-step equations by inspection, guess and check, and inverse operations. There are a few challenge and word problems as well.

To help students prepare for this summative assessment, today in class students received a package of review questions and were given the period to work on them.

For those who would like another copy or lost their copy from today, a new copy of the review can be found HERE.

I am hoping that all students will have a chance to complete (and check their answers) to at a minimum, questions 1, 2, 3, 5 and 8. These questions constitute the “has it” questions. Students looking to go for proficiency or mastery should also try the other questions on the review. Answers to all of the review questions can be found in this document or in the video answer key (below):

Students that are away for this assessment will be writing it at lunch on Monday, December 10.

Thanks!

 

 

 

 

What’s up this Week (Dec 3-7)

December is here and that means only three weeks left before the holidays. We will be working hard until the end of December in order to finish up our Algebra unit and a mini-unit on lines, angles, and geometric constructions. If families are planning on starting their holidays a little earlier, they are encouraged to continue following the blog posts to see what is happening and (hopefully) stay up with things.

Here is a list of upcoming dates and events:

  • December 1 – Bread Mold Lab (DUE) for 7-10 science students
  • December 3 – Check In on Solving One-Step Algebraic Equations (math)
  • December 4 – Bread Mold Lab (DUE) for 7-09 science students
  • December 7 – SWYK: Solving Algebraic Equations (math)
  • December 18 – SWYK: Geometric Constructions (math)
  • December 20 – Movie at Landmark Cinemas

Grade 7 Math
Please note that the SWYKs from last week have been marked but are not being handed back until all students have had a chance to write. All marks are posted in student’s online assessment trackers in case they are interested.

Our focus for the latter half of the past week and the upcoming week is solving one- and two-step algebraic equations using inspection and inverse operations (with a focus on the balance model). As we have already covered one-step equations, on Monday, students will write a short “Check In” so that I can make sure that students are getting the concept before moving on. Students were given a practice sheet to complete over the weekend for homework. Some additional resources on this topic can be found below:

Next week, we will be solving two-step equations using inverse operations and SAMDEB (order of operations in reverse). The SWYK next Friday will involve solving equations by inspection and using inverse operations. It will also involve word problems where students must create a formula and then use their formula to solve the problem.

For example:

The sum of two numbers is 100. One number is 64 more than the other number. What are the two numbers? Create an algebraic equation to help you solve the problem.

This topic can be a tricky one so we will be devoting our class time to developing methods to solve these problems as well as practicing the basic procedures. Students looking for some additional reinforcement for these topics can check out the following:

Grade 7 Science
With the completion of the end-of-unit SWYK and the Bread Mold lab, we have completed our unit on “Interactions within Ecosystems”. The students worked incredibly hard on these last two assessments and I am so proud of them. I have a little reward in store 🙂

We are also going to take our foot off the gas so that students can focus their energy on the math.

Our next unit is called “Form and Function”. It is related to the balance between the appearance of a structure and the purpose of a structure. For example, a chair may be really cool to look at but super uncomfortable.  We will also be exploring the forces (both external and internal) and loads (both static and dynamic) that impact the success of a structure. Although we will be dipping our toes into this unit, we really won’t get into the meat of the content until after the break.

Those who want to check out some of the topics and the final project can visit the unit page HERE.

What’s up this Week (Nov 19-23)

Am I the only one that put on Christmas music while cooking supper? Loving the snow right now! Busy week coming up as we are finishing up our first science unit, completing the final section of the math project, and parent-teacher interviews are (finally) here.

Speaking of interviews, although all of my time slots are filled, I am certainly willing to stay a bit later or cut my supper shorter in order to make sure that parents can meet with me if they want. Also, for those not able to attend but wanting to check in, feel free to send an email anytime!

I am shifting a few deadlines around in order to allow more time for students to complete them with quality as we lost a few classes last week due to assemblies.

Here is an updated list of upcoming due dates and events:

  • November 19 – Mystery Number Project Parts #2 and 3 DUE (math)
  • November 21 – SWYK: Food Webs (7-10 science only) – find more info HERE
  • November 22 – Check In: Evaluating Algebraic Expressions and Formulas (math)
  • November 22 – Early Dismissal @ 1:20 p.m. (7-12)
  • November 22 – Parent-Teacher Interviews, starting @ 2:00 pm
  • November 23 – SWYK: Food Webs (7-04/7-09 science only) – find more info HERE
  • November 26 – SWYK: Writing and Evaluating Algebraic Expressions (math)
  • November 28 – Bread Mold Lab (DUE)

Academics

Grade 7 Math
Last week, the focus was on writing algebraic expressions and equations and translating these to written statements. For example, n + 2 = 5 can be written as “the sum of a number and two is five”. Students completed a quick check in on these topics and began an assignment entitled “Mystery Numbers“. Although Parts 1-3 of this assignment were due last Thursday, due to some interruptions in our schedule, I am extending the deadline to Monday. Any student who has not completed Parts 1 through 3 on the online document that was shared with them via email and is in their Math folder (in google drive), should be doing so this weekend.

Next week, we shift to evaluating expressions by substituting numerical values in for the variables.

For example:

Evaluate 3m + 2n where m = 4 and n = 3

= 3m + 2n
= 3(4) + 2(3)
= 12 + 6
= 18

We will also be solving algebraic word problems and learning about checking the left side (LS) and right side (RS) of an equation to see if the value for each variable is correct. Finally, students will be finishing up the final portion of the assignment (it will be due Friday).

Two new math space tasks on substituting into algebraic expression will be released on Sunday and Wednesday of this week.

Students looking for some additional resources to clarify or reinforce their learning at home can check out the following:

Grade 7 Science
Originally, we were going to finish up our bread mold lab early this week, but I want to take some extra class time to review the concepts from the second half of the unit. As our end-unit test is this week (Wednesday for 7-10 and Friday for 7-09), I think that by taking this extra time, students will be more confident going into the test. We will finish up our bread mold labs next week.

I already posted a bunch of information for the upcoming test HERE. Students should be familiar with all of the terms and concepts listed of the test outline page.

For school-wide news, please check out the Trinity weekly newsletter HERE or following the Holy Trinity Parent Council on Facebook HERE.

Food Webs Test (Next Week)

In grade 7 science, we have completed the Interactions within Ecosystems unit. Students will be writing a test on the content of the second half of the unit in the coming week:

  • Wednesday = 7-10
  • Friday = 7-04/7-09

Next week, all classes will complete a series of review questions using a Jeopardy style game but there is still lots of studying that the students should be doing at their homes over the weekend in preparation for this test.

Like the previous mid-unit test, there are several terms students should be aware of and  should be able to identify and explain each term. Students have been making science notebooks including much of this information (I am hoping that they will be using these while studying) which they are encouraged to bring home and review. The following text pages and links will also be extremely helpful to reinforce the concepts from class:

Here is a rundown of the test and the concepts that students should know before writing:

TEST COMPOSITION

Part A (Knowledge and Understanding)

  • Multiple Choice (14 questions)
  • Matching (9 questions)

Part B (Communication)

  • Paragraph answers (3 questions) – students will have the choice to write their answer or record themselves stating their answer orally

Part C (Making Connections/Applications)

  • Food web analysis (4 question)
  • Graphical analysis (1 question)

CONCEPTS

1) Classifying organisms in a food chain or web

  • Terminology: producer, consumer (primary, secondary, tertiary), decomposer, detritivore, scavenger, carnivore, herbivore, omnivore
  • Example Question: In the food web, identify the secondary consumer and explain your choice.
  • Example Question: Which organisms in the food web can be found in more than one feeding level?

2) Energy transfer in food chains and webs

  • Terminology: food chain, energy pyramid (pyramid of numbers)
  • Example Question: How much energy is passed on to the next organism in the food chain? What happens to the other energy?
  • Example Question: If grass creates 2300 kJ of energy, how much energy does the rabbit receive when it eats the grass? Explain.

3) Interactions within food webs

  • Terminology: equilibrium, carrying capacity
  • Example Question: Using the food web, explain three things that would happen if the grasshoppers were removed from the ecosystem.

  • Example Question: Come up with a scenario that could result in the following graph:

graph_foodchains

Students will have the entire 50-minute block to write the test. Those looking for even  more clarification/resources can check out the Ecosystems page on the blog.

What’s up this Week (Nov 12-16)

Thanks to everyone for contacting me regarding interviews. My rule of thumb is that if your child received a “D” (= “Progressing with Difficulty”) on the progress report, I would like to meet with you. If your child received a “V” (= Progressing Very Well) or “W” (= Progressing Well) on the progress reports, I do not need to meet with you. Saying that, any parent wanting to check in with me is encouraged to touch base with an interview or via email.

As of now, all of my interview times are booked but please email me if you would like to meet – we can definitely make something work!

Here are some upcoming dates:

Grade 7 Math
Last week, we started a new unit and new strand: Algebra! So far we discussed that a variable can represent an unknown (as if n + 3 = 5; n = 2) or a changing quantity (C = 2 + n; n can be different values dependent on C). We also practice how to write an algebraic statement from words (e.g. three less than the sum of a number and 2 can be written as n + 2 – 3). This week, we are going to continue playing around with algebraic statements. On Monday, we will discuss the difference between an expression and an equation. On Tuesday and Thursday, students will be working on an in-class assignment involving writing algebraic equations related to three mystery numbers (this one is NOT going home – it must be completed in class). Those curious about the assignment can check out the outline HERE.

Wednesday’s class is cancelled as we will be attending the Author Presentation and Friday’s classes are cancelled as it is a PD Day.

I have released two new MathSpace tasks that students should be completing at home to practice the concepts from class. Also, students looking for additional practice can check out the following:

Grade 7 Science
As we continue our discussion related to Food Chains and Webs, students in 7-10 will be running simulations using the Explore Learning Gizmo tool (7-09 did this last Friday). On Tuesday and Wednesday, all classes will be dissecting an owl pellet (a.k.a. owl vomit ball) to see what their owl recently ate by matching the bones to a bone guide.

I love this task and seeing what great scientists the students can be!

What’s up this Week (November 5-9)

Happy Friday!

Assessment duotangs in math and science have been distributed (parents, if you haven’t seen them yet, ask your child to bring them home). Also, progress reports were sent home last Thursday. Parent-teacher interviews are booked online on a first-come, first-serve basis. Keep in mind that each teacher has anywhere from 80-150 students and there are only 20-30 interview times. If you are unable to book a time that works, contact the teacher to see about setting up a phone interview. It is highly recommended to book an interview if your child received a “Progressing with Difficulty” or has poor Learning Skills marks on their progress report. A reminder that interviews will be on Thursday, November 22 starting at 2 pm.

Grade 7 Math
Congrats to all the math students who got their Stock Market Project completed and submitted by today’s deadline. I know that it was a lot of work and I look forward to checking out the portfolios this weekend. We also finished up our last topic – Subtracting Integers – this week. On Monday, we will be reviewing both adding and subtracting and looking at some additonal challenge and word problems involving these concepts. On Tuesday, students will write a SWYK on Adding and Subtracting Integers. This will conclude the Number Sense strand for Term 1. Since Wednesday is the 67s Game day, we will be starting our Algebra unit on Thursday. Over the weekend, students are encouraged to complete the assigned MathSpace tasks to prepare for the SWYK. I have added two additional tasks (a review on both operations and one involving Word Problems).

There will be an extra help session at the beginning of lunch on Monday (bring your lunch) focused on Subtracting Integers for anyone who would like some further clarification and/or practice before the SWYK.

As for the algebra concepts, I would prefer that students concentrate on reviewing the materials for Integers but after Tuesday’s SWYK, students could check out the following resources to prep them for the upcoming Algebra unit.

Grade 7 Science
There will not be much science next week as Wednesday is the 67s Game Day and on Friday the Remembrance Day ceremony will be during our (7-09) science block. Our focus will continue to be on Food Chains and Webs, reviewing the terminology associated with chains and webs and working on an activity involving an Alien Ecosystem. We will be continuing to observe our bread mold experiment as well.

As for home reinforcement/practice, students are encouraged to check out the following:

Grade 7 Math
We are entering our third (and final) week of the integers unit. Last week, our focus was on adding integers. On Monday, students will be writing a quick formative “check-in” on adding so that I can ensure they are demonstrating a basic understanding before we move on. Also on Monday, we will be discussing the final components of the Stock Market Project. Students NEED to have all of their stock data tables completed before Monday’s class as we will be learning how to create graphs using google sheets. Stock Market Portfolios will be due at the end of the day on Friday.

Our curriculum focus this week is on Subtracting Integers. We will be working on this concept in class on Tuesday and Thursday and then reviewing both adding and subtracting on Friday is preparation for our final SWYK next Monday (November 5). There are THREE new MathSpace tasks on Adding and Subtracting Integers that are being released today. Also, students looking for some additional reinforcement can check out the following links on subtracting integers:

Grade 7 Science
With the completion of our mid-unit tests last week (all assessments are being sent home on Tuesday for parents to see), we are now into the second half of our ecosystems unit. This portion is focused on feeding relationships (food webs). Students are HIGHLY encouraged to review the following material in preparation for our discussions this week:

A reminder that progress reports are being distributed this Thursday. Parent-teacher interviews will be held on November 22.

What’s up this Week (October 22-26)

Stock markets, science tests and picture retakes – that is the week in a nutshell. Lots of information has been posted online in regards to resources for math and science. Please note the following important dates:

  • October 23 – Ecology Chapter Test (science) – more details in this post
  • October 23 – SWYK on Representing and Comparing Integers
  • October 24 – School Photo Retake Day
  • October 31 – Charity Cake Auction
  • November 1 – Progress Report Cards Issued
  • November 7 – Ottawa 67s Game!

Academics

Grade 7 Math
Last week, we started to investigate integers. We plotted them on number lines, represented scenarios as integers (e.g. a deposit of $50 = +50), and compared and ordered integers. On Monday, we will be completing some challenges related to these topics and on Tuesday students will be writing a short SWYK.  There are several practice games and quizzes available in the stock market workspace for kids to practice over the weekend.

Also, last week we started our major project: Stock Portfolios. Each student created an investment portfolio and invested anywhere from $6000-10000 in three companies. Students had to do some preliminary research on the past stock trends on the companies and determine how many shares to buy as part of their investment. All shares were purchased based on the closing cost from Friday, October 12. For more information on this project, check out the Project Outline HERE.

For students at home, they should be completing the following tasks at some point over the week:

  • completing the MathSpace Tasks that have been assigned (Representing and Comparing Integers)
  • tracking the closing costs of their stocks daily (these are all posted on twitter each evening)
  • if they have not done well in a previous skill that has being assessed (e.g. multiples, powers, order of operations), they are encouraged to work at home (or during extra help sessions at school) to improve their understanding (then they can then submit a reassessment request)

Grade 7 Science
On Tuesday, students will be writing their mid-unit test (see this post for details). In the latter half of the week, we will be using microscopes to see if we can find any microorganisms in the samples of pond water we brought back from our pond study.

Also, (providing all students are present for the test on Tuesday) I will be handing back all of their marked assessments (labs, tests) back along with a mid-unit grade report (I will be basing my progress report evaluation on this data).

We will be starting the second half our our unit (focus will be on feeding relationships and food webs) next week.

For school-wide announcements (including more info on immunizations), check out the Trinity Weekly News HERE.

What’s up this Week (15-19)

I am sending out this post a little earlier than normal since there are components that should be completed this weekend. With progress reports looming on the horizon (distribution on November 1), teachers are finishing up some final evaluations and therefore I recognize that this can be a stressful time for students. I have moved the math SWYK and the science test back to give students more time and I encourage students to continue to be open with me in regards to their workload. I am definitely open to moving some of my deadlines if they feel swamped in their other classes!

Here is a list of upcoming dates:

Upcoming Events and Dates

  • October 15 – SWYK: Order of Operations (math) – more details below
  • October 16 – Ecology Check In (practice test = formative)
  • October 17 – “Oh Deer” assignment DUE (science) – more details below
  • October 17 to 19 – 7/8 Immunizations
  • October 23 – Ecology Chapter Test (science) – more details in this post
  • October 24 – School Photo Retake Day
  • October 31 – Charity Cake Auction
  • November 1 – Progress Report Cards Issued
  • November 7 – Ottawa 67s Game!

Academics

Grade 7 Math
A reminder that on Monday, students will be writing their SWYK on Order of Operations. Last week, I handed out a practice sheet which students are HIGHLY encouraged to take the time to complete. If students were absent or lost their copy, they can download a new one HERE. Once students complete the practice sheet, they should take some time to watch the video answer key to clarify any misunderstandings. I think that it might also be helpful to watch someone else go through the problems. The SWYK is almost identical to this practice.

Next week, we will be starting our unit on Integers. To get us going, students will be setting up stock portfolios. Each student will be “investing” and following three companies over the next two weeks (more info to follow in a separate post) in order to determine their overall profit/loss of their portfolio.

This week, we will be defining, identifying, and comparing integers with and without a number line. This is the first time that Integers are being formally introduced so we will be going slow at the start. The following are some additional resources that students can use at home to reinforce/clarify concepts on this week’s topics:

Grade 7 Science
We are coming to the halfway point of our Ecology unit and that means it is time for students to “Show What they Know”! On Tuesday, September 23, students will be writing a test on the content covered so far in science. Students can find much more info on the test HERE. In order to help students prepare, students will be writing a shorter practice test this Wednesday. I want students to experience a “high school” science test – one that doesn’t “count” – so that they have a better idea of what I expect. We will also be going through a review of all content and I am hoping to introduce some new ways that students can organize their work and prepare for writing tests.

In addition to preparing for the test, students will also be finishing the analysis for the “Oh Deer” simulation we started last week.

Students will be graphing the population of “deer” over the 14 seasons and then completing some discussion questions. I am giving students an entire period to work on this in class (I feel as though this should be enough time to complete the entire assignment but students who did not finish will have to complete it at home). 7-09 worked on this last Friday and should be finishing up the assignment this weekend. 7-10 will be working on this Monday in class. For now, I have set the deadline for this task as Tuesday, October 16. Students can download a new blank copy of the assignment HERE (but they will have to get the results from a classmate).

For school-wide announcements (including more info on immunizations), check out the Trinity Weekly News HERE.

Mid-Unit Ecology Test

In grade 7 science, we have made it to the halfway point in our unit on Interactions within Ecosystems. Students will be writing a test on Tuesday, October 23. Although it is still over a week away, I want to give plenty of warning ahead of time so that students can be adequately prepared.

Last week, students completed an online practice quiz on many of the topics. If students want to complete this online practice again they can do so by clicking HERE (game code is 516823).

Next Tuesday, students will be writing a mock test (which I will mark and get back to them the following class) so they can see what a science test looks like and get a sense of what they know (and what they don’t know) heading into the next weekend. Friday (7-09)/Monday (7-10) in class, we will be also be completing an additional review but there is still lots of studying that the students can be doing at their homes in preparation for this test.

There are several terms to know for this test. Students should be able to identify and explain each term listed below. Students have been adding notes into their science notebooks which include much of the required information (they can use these notebooks on the test too!) but I also want to direct students to the following text and online links that will be helpful in review:

Here is a rundown of the test and the concepts that students should know before writing:

TEST COMPOSITION

Part A (Knowledge and Understanding)

  • True or False (7 questions)
  • Multiple Choice (8 questions)
  • Matching (5 questions)

Part B (Communication)

  • Paragraph answers (3 questions)

Part C (Making Connections/Applications)

  • Determining population amount (1 question)
  • Graphical analysis (1 question)

CONCEPTS

1) Identifying abiotic and biotic factors in an ecosystem

  • Concept: Calculating population rate
  • Concept: Identify, list and explain several different abiotic (e.g. amount of sunlight) and biotic (e.g. competition) factors that limit the growth of a population
  • Example Question: The amount of rabbits (prey) in an area increases. What do you think will happen to the population of foxes (predator) in the same area? Explain.
  • Example Question: The population of mice in a barn is 40. Over the winter 3 mice immigrate, 4 die, 3 are born, and 1 emigrate, what is the new population?
  • Example Question: Choose which graph best represents each scenario… explain your choices.
    • Scenario 1 = There were 3 cold springs in a row
    • Scenario 2 = There were 3 hot summers in a row
