This flipchart is a number bond that can help students make up to 4 number sentences. They can make addition or subtraction. I like to have my students go around the room and each person gets a chance to say what comes next. For example: the first student would write 3, the next +, the next 4, the next =, and the final student would write 7. This way students get a chance to either write or say each component of the number sentence. Another idea is to have students use a deck of cards and draw the top number and make the number bond and sentences that way.
