Math Rainbow Heart Color by Number (Addition) Coloring Page

About This Color by Number Page

A rainbow heart hidden behind addition problems: solve each sum, find the number in the key and color the layer. The key at the bottom uses 7 colors. The sums are small, so they are good practice for kindergarten and first grade.

How to Color by Number

Solve the addition problem in a shape, for example 2+3 = 5.
Find that number in the color key at the bottom of the page.
Color the shape with that color.
Keep going until the whole picture is colored.

Tip

Compare your finished picture with the colored example – then cut it out and give it as a valentine.
