Thursday 11/12- Module 2 Lesson 3

Lesson 3 EQ: How can we write and interpret numerical expressions and compare expressions using a visual model?

You will need your whiteboard & marker to work alongside the video.  As you watch the video, it will stop occasionally to ask you a question.  You need to answer the questions under the video.

(You will need to scroll down to see them, there are 8 questions)

After you watch the video & answer the 8 questions, there will be 2 Problem Sets that you need to complete (by showing your work on the screen). 

*If you are at school for this lesson, you will complete the Problem Sets in your Math Notebook instead of on the computer*

This assignment is worth 100 points.
