About number bonds and complements

Number bonds are the pairs of numbers that make a target: 3 and 7 make 10, 37 and 63 make 100. Choose the target from 10 up to 1000, or the "nines" targets where every pair of digits makes 9.

Write the missing number in a sum such as 37 + __ = 100, or switch to subtraction (100 − 37) to practice subtracting across zeros. For 100 and 1000 you can keep to round numbers (10, 20, 30 ...).
