Topics for December 6th

Algebra I

Today we discussed
We began our discussion of  factoring trinomials using the "Product-Sum" game.  We covered both scenarios where the leading coefficient is 1 and also NOT 1.

**I encourage everyone to download and watch the Google Slides presentations and review how we work on factoring.  You will need to click on the links below to each presentation (there are TWO), and then open with Google Slides.  Once you have it open, click on the "Present" button near the top right of your computer or tablet screen.  From there, you will be taken through the presentations step-by-step with each mouse click.

(This is not the method I taught in class, but it is a good way to work on these.  It's always good to have multiple ways to solve problems.....)

Pre-Algebra

Today we discussed
Today we broadened our discussion of rational number to adding and subtracting fractions.  We focused mainly on problems where the denominators were the same.

Here is an example of adding and subtracting fractions with like denominators:
