Lesson 3 Properties of Operations

Now, to lesson 3, Properties of Operations. 

Properties are like the rules of the math game.  You must follow them to get the correct answer to your problem. You are fairly familiar with some of these properties already, so they will be a review.  There are a few new rules, so make sure these get written into your graphic organizers with a definition that you understand.  And one of the basic properties is not mentioned in this lesson, but we use it the most frequently is the Order of Operations!  Many of you use the "Please Excuse My Dear Aunt Sal" to remember what operation you solve first when you have a string of operations in an expression or equations.  

You must add this Property as well as the other ones mentioned in the videos.

What a talent he has.  

Homework: Read the blog carefully and pull out 2 facts and enter them in your graphic organizers.  Watch the videos and take notes and complete the vocabulary with definitions you understand for this lesson on Properties.
