Students find the missing number in each number bond diagram. The whole (top circle) breaks into two parts (bottom circles). Understanding these relationships builds a strong foundation for addition and subtraction.
Use for math centers or guided practice when teaching number decomposition. These worksheets help students see that numbers can be broken apart and put back together in different ways.
Use counters to model the bonds. Split a group of objects into two parts and ask your child to figure out the missing number. Then use the worksheet to reinforce the concept with written number bonds.
