The same pictures, more ways to color

Color by answer turns math practice into a game: instead of a page of dry problems, every solved problem colors one more square of the picture. Kids work through dozens of problems without noticing, and they check themselves, because a picture that comes out "wrong" shows something was missed.

All 131 color by number pictures come in every operation: addition and subtraction to 10 for kindergarten and grade 1, addition and subtraction to 20 for grades 1–2, and times tables and division for the older grades. Every page has a full-color answer key, and you can print a booklet of 6 pictures at once.

Frequently asked questions

What is color by answer?

A coloring page where each square holds a math problem instead of a number. Solve the problem, find the answer in the key and color the square in its color. When every problem is solved, a picture appears.

Can the colors get mixed up?

No. Each color has its own answer, and no answer belongs to two colors. If a square comes out in a color that does not fit the picture, the problem was probably solved wrong, which is a good chance to check it again.

Which operation suits which age?

Addition and subtraction to 10 for kindergarten and grade 1. Addition and subtraction to 20 for grades 1–2. Times tables for grades 2–4, and division for grades 3–5. Any picture works with any operation.

Do the problems change each time I print?

No. Each picture and operation always gets the same problems, so the whole class gets an identical sheet and the answer key always matches.
