Lesson Planning

Day 1

Check-up

Use inverse operations to solve missing number calculations.

Follow-up

Use function machines to help students see that inverse operations do the opposite of each other.

Day 2

Check-up

Use mental strategies to add amounts of money and find change.

Follow-up

Focus on the three mental strategies to add amounts of money, and ‘counting up’ to find change.

Day 3
