Sailboat Addition to 10 Color-by-Number Worksheet

Solve, then color

This Sailboat page hides 15 math problems, one in every space. Kids add, look up the answer in the color key at the top and fill the space with that color. The finished picture uses white, light yellow, yellow, light blue, blue, red, navy.

A wrong answer shows up as a space in the wrong color, so children can spot and fix their own mistakes before you even check.

Good to know

• Writing the answer in pencil first and coloring second keeps the focus on the math.
• Page 2 is the finished, colored picture: handy for quick checking or as the big reveal.
• No printer? Use "Color online" on a tablet; every space is checked as it is colored.
