Teaching tips and what to try next

Suited to kindergartners who count small groups of objects reliably and are beginning to join two groups. Playing a simple matching game with real dominoes, where each turn you say the total of a tile before placing it, gives the same practice off the page. Next, move to sums up to 12 in Dice Addition or try the facts as numbers in Addition Within 10.

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

Dominoes give young children a picture of addition they can see and touch. Each domino has two halves, and putting the halves together is the same as adding two numbers. This kindergarten worksheet uses domino pictures to practice adding within 10.

The page shows twelve dominoes. Each half has from zero to five dots, arranged in the same patterns found on real dominoes, so the total is never more than 10. Children count the dots on the left half, count the dots on the right half, and write how many dots there are in all in the box. Some dominoes have a blank half, which quietly teaches that adding zero keeps a number the same. Each of the ten versions shows a new set of dominoes and comes with its own answer key.

How to use it: if you have a set of dominoes at home, lay a few on the table and count the dots together before starting. Ask your child to count one half, then keep counting on into the other half instead of starting again at one. When the same dot pattern shows up again, see if your child can name the number without counting, since quick recognition of small groups is a big step toward adding in your head. Let your child touch each dot with a finger or a pencil tip so no dot is counted twice.

The answer key shows every total. When your child is ready for bigger totals, try our Dice Addition worksheet. To practice the same facts with numbers only, try our Addition Within 10 worksheet.
