Kids will have fun engaging in pretend play with pizza slices while learning their basic subtraction facts. I like to give the students real miniature pizza pans which I purchased on Amazon. This activity also includes a challenge page for gifted and advanced learners. A Google Slides version for distance learning or center time is also included. This activity is compatible with lesson 2.1 of the Go Math curriculum, but it can be used with any program. Click here to download Pizza Party: A First Grade Math Subtraction Activity!
