2.2: Bags of Almonds

A baker has 12 pounds of almonds. She puts them in bags, so that each bag has the same weight.
Clare and Tyler drew diagrams and wrote equations to show how they were thinking about 12 \div 6.

How do you think Clare and Tyler thought about 12 \div 6? Explain what each diagram and the parts of each equation could mean about the situation with the bags of almonds. Make sure to include the meaning of the missing number.

Pause here for a class discussion.

Explain what each division expression could mean about the situation with the bags of almonds. Then draw a diagram and write a multiplication equation to show how you are thinking about the expression.

a. 12 \div 4
b. 12 \div 2
c. 12 \div 1/2
