Tues 4/12

We discovered our third and final method to solve systems of linear equations today: solving by using linear combinations (also sometimes called the elimination method) inLesson 12.1.

It takes a little bit of practice to get this technique down, but I think you'll find it quite helpful to quickly and easily find the solution of a linear system of equations.

Be sure to use the example on page 652 to help you with your homework tonight!

Also, we'll be taking Common Assessment #5 on Monday, April 18th. A study guide has been posted in the Document Locker.

Homework: Textbook pages 631-632 (#1a-d)

Tues 4/5

Today we introduced ourselves to asecond method to solve systems of linear equations: Substitution!

We're going to be working with this method all week, so you'll have plenty of time to get comfortable with the ins and outs.

Today was a good intro. Tonight's homework will be a good chance to test out your new skills.

Homework: Textbook page 603

Wed. 3/30

Today we continued with a lesson on systems of equations.11.2 We've got A LOT more to do with systems, but today is a continuation of yesterday.


Homework: Finish any unfinished classwork, pg. 603-604 in addition to talk the talk pg. 619.then do textbook pages 602-606 (Problem 2). You can use Desmos instead of doing the table and graph by paper if you prefer.

Tues 3/29

We dove into Chapter 11 today with an introduction to systems of equations in Lesson 11.1. We've got A LOT more to do with systems, but today was a good introduction for us.

For those that were absent today, be sure to do all of Problem 1 on your own before attempting your homework. You can use this blank copy of 11.1 if you haven't ripped out your textbook pages yet.

Homework: Finish any unfinished classwork, then do textbook pages 602-606 (Problem 2). You can use Desmos instead of doing the table and graph by paper if you prefer.

Wed. 3/9

We finished out the chapter today with Lesson 10.4 where we investigated the slopes of parallel and perpendicular lines.

Instead of working through the textbook pages, we did a Desmos Activity that covered the same concepts. If you didn't finish it in class, please do so at home tonight. Head to student.desmos.com and type in the corresponding class code.

If you were absent today, you're welcome to either do the 10.4 textbook pages, or the Desmos Activity instead. Just make sure you do one of them to prepare for tomorrow's test.

Tues 3/8

We wrapped up Lesson 10.3 today using all the new concepts we've learned to find missing angle measures.

We'll finish Chapter 10 tomorrow with Lesson 10.4 and an awesome Desmos Activity. Then we'll take our Chapter 10 test on Thursday.

If you're going to be absent this week, I encourage you to do your work ahead of time so you're ready for the test!

Homework: Textbook page 561

Thurs. 3/3

Today we worked on pages 549-554 in Lesson 10.3, investigating the relationships formed by all the pairs of angles we learned about yesterday.

Some of the key pairs of angles are congruent, some are supplementary, and some have no relation at all, depending on whether or not the two lines are parallel.

Need a protractor at home? Here's a printable protractor that'll help you out until you can purchase a plastic one.

Homework: Finish textbook pages 553-554
