Teaching tips and what to try next

A first step for kindergartners who count to 5 without help and are just starting to put two small groups together. Hiding a few buttons under one hand while the rest stay in view, then asking how many are hiding, turns each bond into a quick guessing game. Next, try bigger wholes with Number Bonds to 10 or write the parts as equations in Missing Addends Within 5.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

A number bond is a simple picture that shows how a number splits into two parts. The whole sits in a circle at the top, and the two parts sit in circles below it, joined by lines. Kindergartners who see that 5 can be 2 and 3, or 4 and 1, or 5 and 0, are building the number sense they will use for adding and subtracting. This kindergarten worksheet practices number bonds with wholes up to 5.

The page has twelve number bonds. Every whole is a number from 1 to 5, and one of the two parts is missing. Children look at the whole and the part they can see, then work out the part that is hiding and write it in the empty circle. A few bonds use zero as a part, which shows that a number and zero still make the same number. Each of the ten versions has a new set of bonds and its own answer key.

How to use it: before starting, hold up five fingers and fold some down. Ask how many are up and how many are down, then say the bond together, such as five is three and two. Small objects work well too. Put the whole number of counters in a cup, tip some out, and ask how many are still inside. If your child guesses, have them count the part they know and then count on to the whole.

The answer key shows every missing part. When these feel easy, try our Number Bonds to 10 worksheet. For the same idea written as equations, try our Missing Addends Within 5 worksheet.
