Lesson 4 EQ: How can you convert numerical expressions into unit form as a mental strategy for multi-digit multiplication?
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*
