About this Dory subtraction coloring page

This Dory page turns subtraction practice into a mystery picture. Students solve each of the subtraction facts, match the answer to the color key, and fill in the square, so the picture only appears when the work is right.

How to use it

This page supports subtraction fact fluency. It lines up with Common Core standard 1.OA.C.6 and 2.NBT.B.5 (subtract within 20 and within 100). It is typically used with students in grades 1-3.
