Color by number math worksheets
Every space holds a math problem. Solve it, find the answer in the key (“12 = Blue”) and color. Pick the skill, download the PDF, and page 2 shows the finished picture.
How math color by number works
Each space has one problem, like 7+5. The key at the bottom lists answers and colors: 12 = Blue. Solve, color, repeat — the picture appears as the answers come in, so kids can spot a wrong answer by its color.
- Addition and subtraction within 10: kindergarten and grade 1
- Addition and subtraction within 20: grade 1–2 fact fluency
- Multiplication and division facts: grade 3–4
Every problem comes from the same generators as our math drill worksheets, and every answer is checked by automated tests before it reaches the page.
