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.
#1- What is a "sum"?
#2- What does it mean when you double something?
#3- How do you think you would write "the sum of 21 and 4, doubled" as an expression?
#4- How many rectangles should you draw if it says 5 times the sum of 7 and 23?
#5- Which expression represents the model he drew?
*5 times the sum of 7 and 23*
#6- What is a "difference"?
#7- Explain how both expressions are similar and how are they different.
#8- Explain why the left side is larger than the right side.
