Multiplication, Division

How many NOW?

Chrissy Newell has a great dot activity to illuminate multiplication through a number talk. Check out her original post here, and her website:

 

Multiplication

How to use: Ask: What do you notice? What do you wonder? What could this look like for other problems?

 

Multiplication Factors

How to use: Ask: What do you notice? What do you wonder? What equations would match each array? What is the pattern?

 

Commutative Multiplication

How to Use: Watch and ask: What do you notice? What do you wonder? What is the same? What is different? Does this work with other numbers? How could this make solving other problems easier?

Ways to See 6×5

How to Use: Watch and ask: What do you notice? What do you wonder? What else can you think of? How do these help you think about 6×5?

 

Ways to Solve 18×5

How to Use: Ask students to solve 18×5 and show it visually. Watch this visual and ask: Which one was most similar to yours and why? Choose one of these strategies and explain how it works.

This visual is inspired by Jo Boaler and www.youcubed.org, a great place to learn about productive mathematical mindsets, research, and activities.

 

Types of Division
