This is a math game that students can play as a small group, with partners, or individually. Numbers 4-9 are on strips. Each card is divided into three sections. The first section has the number in it. The next two sections have dot sets that make up the total. Use a "What's My Number?" flap to cover the third section. Students look at the total and then at the first dot card. They determine the missing part. They may read the number sentence as a subtraction sentence or addition sentence.
