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.

 

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?

 

Multiplication Connection to Hundreds Chart

How to Use: Watch and ask: What do you notice? What do you wonder? Can you predict how it will fall and/or break up? Can you predict what the next number will be by using what you know about the hundreds chart? (Read Graham Fletcher’s post about the “upside down” hundreds chart used in this video here)

 

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.

 

Arrays Collide

 

Atomic Dots

 

Types of Division

How to Use: Watch and ask: What do you notice? What do you wonder? What is the same? What is different? What story could match the first one? How would the story have to be different to match the second one?

 

Division into Groups or Array

How to Use: Watch and ask: What do you notice? What do you wonder? What is the same? What is different? What story could match these? What equations could match?
