Subtraction Color by Number

Use it as a half hour to forty-five minute math block, a homework page, or a quiet station while you work with a small group. A child solves a square, looks up the difference in the legend and colors that square. Turn on the answer key to check the finished picture, or use 5 versions in a classroom so nearby desks see different pictures and different problems. New version gives a fresh one for practice at home.

Differences from 3 to 17 and no negative answers means children take a smaller number from a larger one, usually within twenty. Common errors are counting down in the wrong direction or reversing the numbers. A child who is shaky can lean on a number line or fingers while building speed. Pair it with the addition page to show how the two operations undo each other.

Pick this page after your child has done the addition sheet and wants to see the reverse. Younger children can count back on a number line for each square. For older kids, challenge them to do rows aloud without help. The picture is random, so New version brings both a new picture and new problems. Try Multiplication in Mode next for a step up.

Can the answers be negative on this page?

No. Every problem takes a smaller number from a larger one, so differences are from 3 to 17 and none go below zero. That keeps the sheet suitable for children who have not met negative numbers.

How long does a full subtraction sheet take?

Plan on half an hour to three quarters of one for most second graders. A first grader may need two sittings. Splitting at the halfway line keeps the picture exciting without tiring a child who is still learning the facts.

Is there a way to check the whole page quickly?

Yes. The answer key shows the finished picture with every square colored. Hold it next to the child's sheet and any square in the wrong color shows up at a glance.
