Subtraction Color by Code: Take Away, Then Color

On this color by code worksheet, every color has to be earned by taking away. Twelve outline shapes each hold a small take-away problem with a starting number up to 12 — 7 minus 3, 12 minus 5 and their friends. The child works the problem, finds the answer in the four-color legend, and colors the shape accordingly. Twelve little subtractions later, every shape on the page is colored and the math has quietly happened.

Subtraction usually gets far less playful practice than addition, which is precisely why this page exists. Take-away facts up to 12 need the same instant familiarity as their addition cousins, and a dozen repetitions with a crayon reward attached is a much easier sell than a column of bare problems. The legend adds a self-checking twist: an answer that is not in the code at all sends the child straight back to the problem, no adult needed. Watching which shapes get colored confidently and which cause a pause tells a teacher exactly which facts still need work.

It prints free as a PDF whenever the crayon box is ready. The add and subtract mixed page is the natural next step — same crayon reward, but now the operation sign has to be read before every move — and the original color by code covers the addition side of the family.
