About this coloring page
A printable color-by-number mystery picture worksheet with a hidden heart. 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. Add patterns inside the hearts.
This page by the numbers
The picture has 143 numbered squares on a 13 x 11 grid, colored with 3 crayon colors. Red (number 5) fills the most squares: 84 of them. Pink (number 7) is used the least, with 2. Every answer is a number from 3 to 7, so each answer matches one color in the key.
- 3 = light blue: 57 squares
- 5 = red: 84 squares
- 7 = pink: 2 squares
Coloring ideas
- Pink, red and purple are perfect for Valentine's Day.
- Try a rainbow of hearts.
- Have your child say each fact out loud while writing the answer.
- Color one number at a time: find all the 1s, then all the 2s, and so on.
