About this coloring page
A printable color-by-number mystery picture worksheet with a hidden mushroom. Solve each addition problem (sums up to 10) and color the square by its answer. Every square is a quick math fact, so it doubles as addition or subtraction practice. Use small objects like buttons or cereal to check tricky problems.
This page by the numbers
The picture has 143 numbered squares on a 13 x 11 grid, colored with 5 crayon colors. Red (number 6) fills the most squares: 55 of them. White (number 4) is used the least, with 9. Every answer is a number from 3 to 8, so each answer matches one color in the key.
- 3 = green: 13 squares
- 4 = white: 9 squares
- 5 = brown: 14 squares
- 6 = red: 55 squares
- 8 = light blue: 52 squares
Coloring ideas
- Have your child say each fact out loud while writing the answer.
- Follow the color key exactly to see the mystery picture appear.
- Use markers for bold, even squares.
- Color one number at a time: find all the 1s, then all the 2s, and so on.
