Absolute Value Videos - Lesson 9/14

Today in class we began our chapter on Absolute Value!  In both class, Chapter 2 is about Integers and begins the same way.

Here's a recap of today's lessons:

Integers are the positive and negative whole numbers on a number line.
Absolute Value is the distance a number is from zero on a number line.

Here are a couple Khan Academy videos about Integers and Absolute Value for your viewing pleasure. If you have homework that you're working on this weekend and need a little brain refresh, these should do the trick!

Here's one I took in class of one of your brave classmates demonstrating how to "walk to the number line," remember this is a great strategy to use when finding the absolute value. We can imagine a number line in our heads and "walk it" or you can draw one out and use your finger!

Here's a reminder for how to graph points!
