Teaching tips and what to try next

Meant for kindergartners who can add within 5 using fingers or objects, as in Addition Within 5 With Pictures. Hiding a few crackers under a cup and asking how many are hidden is a quick game for the same idea. When these feel easy, try larger totals in Missing Addends 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

Kindergartners are expected to add and subtract within 5 quickly and easily by the end of the year. A missing addend equation, such as 2 + ___ = 5, asks a child to think about the parts of a small number instead of just counting up. This kindergarten worksheet gives sixteen equations like that, with every total between 1 and 5.

In each equation, one of the two parts is missing. Sometimes the blank comes first, as in ___ + 1 = 4, and sometimes it comes second, as in 3 + ___ = 5. Two equations on each page use 0 as one of the parts, which helps children see that 5 + 0 is still 5. Because the numbers are so small, children can solve every problem with their fingers or five small objects. Each of the ten versions has a new mix of equations and its own answer key.

How to use it: give your child five pennies and two cups. Put some pennies in one cup and ask how many must go in the other cup to make the total. Then try the same question with the worksheet. Reading each equation aloud as a question helps: "Two and what make five?" If your child writes the total in the blank, cover the total with a finger and ask what the plus sign means.

The answer key shows every missing number. For practice with adding pictures, try our Addition Within 5 With Pictures worksheet. When totals to 5 feel easy, move to our Missing Addends Within 10 worksheet.
