## 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

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:

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)

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:

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.

## 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:

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:

### Upcoming Events and Dates

• November 26 – SWYK: Writing and Evaluating Algebraic Expressions (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:

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.
