Wednesday:
1. Let's start by just checking out this interesting site that has some pretty large numbers: http://www.usdebtclock.org/
2. Today our learning target is to see what Exponential Growth and Decay look like graphed and in equation form. Take a few minutes to look through these interesting examples of exponential growth and decay: http://passyworldofmathematics.com/exponents-in-the-real-world/.
3. Today, you are going to investigate about exponential growth and decay by way of a video and some pre-written notes. Please read the notes through first, then follow along on the notes again as you watch this video:

4. If you feel you need more clarification, here's another video to watch that will help clarify exponential growth and decay. If you are understanding growth and decay, go on to #5 instead.: https://www.khanacademy.org/math/algebra/introduction-to-exponential-functions/exponential-growth-and-decay/v/exponential-growth-functions
5. Here is a video of one exponential growth and one decay problem completely worked out. This should help you with your practice work: https://www.khanacademy.org/math/algebra/introduction-to-exponential-functions/solving-basic-exponential-models/v/word-problem-solving-exponential-growth-and-decay
6. Exponential growth and decay homework (due Monday)

April 22-26
Monday: Factoring a GCF
We will be doing the REVERSE of multiplication......FACTORING!
Today we will introduce factoring and how we will use a flow chart to determine which type of factoring we are doing:
Factoring flow chart: Factoring Flow Chart
We will also remind ourselves of how to find a GCF using factor trees. With a partner, try finding the GCF's using these notes: Tunnel - GCF Practice1- with variables.notebook
Our notes on GCF's are: Factoring out GCF.notebook
Tuesday: Review perfect squares: https://quizlet.com/2762716/flashcards or http://www.sporcle.com/games/TheCheese/perfect_squares
Wednesday: Difference of two Squares; notes

3. http://www.sporcle.com/games/TheCheese/perfect_squares - perfect square practice
HW. Worksheet p. 36; due Thursday.
Thursday:Check for understanding on GCF and DOS; start thinking about how to factor polynomials of the form xsquared + bx + c.
Let's begin by practicing these diamath sheets. These will help us see that to factor trinomials, we need to be looking for 2 numbers that multiply to be a certain number and also add to be another number:
DIAMATH PRACTICE SHEETS.pdf
Notes: 7.4.A factoring xsquared + bx +c.notebook
Homework is due Monday: Factoring trinomials ws 39, optional 40.pdf
Friday: Factoring x2+bx+c
Homework: Worksheet (do odds or evens on both sides)
Monday: Correct WS from Monday
My favorite wrong
