Here is a link to the video from Problem  2 in the homework set:  VIDEO

Please complete the entire problem set tonight for homework.

# Lesson 1: Piecewise Functions

I'm not sure how helpful these "notes" will be from today's class. A lot of what we talked about in class didn't show up on the Promethean Board.

Please complete 1 - 3 on the Problem Set over the weekend.  This is from the packet you received yesterday.

# Quiz Wednesday:

Today in class we began to review for Wednesday's Quiz.  Here is a link to our review notes:  NOTES

Here are some practice problems to make sure you understand all of the key concepts:

While this assignment will not be graded, it is a great way to measure how prepared you are for the quiz. Do as many or as few problems as you think are necessary.  Of course, there is no harm (and a lot of benefit) in doing all of them!

# Multiplying Polynomials:

If you skip ahead to the problem set, beginning on page S.47, please complete the following multiplication problems using  the area model AND vertical method:  e, f, g, k, n

Doing each problem both ways is a great way to check your work for accuracy and precision.

Here is a copy of today's class notes:  A3_11_25

# Practice Proof:

Tomorrow we will begin class with some Bellwork - a short quiz making sure you understand how to format a proof, and limit your steps to changing one thing at a time.

Prove that (a + x)(bc + 1) = xbc + x + a + abc

# Proofs!

Today in class you did an awesome job with our introduction to mathematical proof.  This is an EXTREMELY important skill which will help you with Geometry next year at New Trier.

Please complete 1 - 9 (but skip 8) tonight for your homework.

There is a typo in #6.  Hopefully you fixed it in class today.

# Take the Night Off

You worked really hard in class today, and did a great job figuring out how Jill, Fatimah, Edna, and Michael found the area of the (x + 2a) square.

Tomorrow we will continue our study of the Commutative and Associative Properties, and use them to introduce the concept of "proof" which is going to be very important for you next year in Geometry.  Please come prepared and ready for 60 minutes of math!

# Multiplying Polynomials!

Today in class you did a great job of making Area Models to find the area of polygon expressions.

Over the weekend, please try the following problems from the lesson packet:  Beginning on page S.28 1, 4 - 6.

6 is a really cool problem.  It take some thought, but we'll talk about it on the blog and and in class on Monday.

# More 9.1

Here are the notes from today's class with some clarification on key points from lesson 9.1:  A3_11_13

It might be a good idea to look over the homework assignment from 9.1 to make sure you understood the lesson as well as you thought you did.
