1. Notes: Targets
Start your notes with these targets:
Start your notes with these targets:
- I can use the structure of an expression to identify ways to rewrite it.
- I can use the distributive property to prove equivalency of expressions.
2. Warm Up: Review
Complete the Khan Academy activity below. This is a review of what you should have learned about distributive property in middle school. If you need a quick lesson to freshen your memory, watch the video to the right and take notes. Here is the Khan Activity: Distributive Property with Variables |
3.) Video: Vocab
Watch this video and copy all the notes. |
|
4.) Video: Equivalent Expressions
Watch this video and take notes. This will introduce what you need to do in the next activity. |
|
5.) Practice 1: 4x + 5y + 3a
Follow the directions from the previous video. Write an equivalent expression for 4x + 5y + 3a.
Follow the directions from the previous video. Write an equivalent expression for 4x + 5y + 3a.
6.) Video: Distributive Property
Watch this video and take notes. |

7.) Practice 2: Show Distributive Property
Show how 4y +3y = 7y is a result of distributive property.
Show how 4y +3y = 7y is a result of distributive property.
8.) Video: Geometric Representations
Watch this video and take notes. You will be using these notes to help you with the next couple activities. |

11.) Notes: Practice 4
Use a picture to represent the expression (a + b + 1) x (b + 1) and then write an equivalent expression using the picture. |
12.) Video: Practice 4
Watch this video AFTER you have attempted Practice 2. See if we did it the same way. |
