Color by Shape: Every Triangle Red

This color by code worksheet runs entirely on shapes — no sums, no numerals, just geometry. Twelve outline shapes are scattered across the page, and the legend at the top gives the rule: every triangle red, every circle blue, and so on through four shape-and-color pairs. The child looks at each shape, decides what kind it is, checks the code, and colors it to match until the whole page is done.

Naming a shape from a flashcard is one thing; picking that same kind out of a scattered crowd of twelve, over and over without losing track, is the real Kindergarten skill, and that is exactly what this page drills. A triangle among stars and circles still has to be spotted as a triangle, and the coloring only comes out right if every one of them is. Because each entry in the code shows the shape beside a color swatch and the color word, a pre-reader can work from the swatch alone while a beginning reader gets the word for free — and learning to use a legend is itself a skill worth growing.

Print the free PDF and let the crayons check the learning. The classic color by number page swaps shapes for numerals as the code, and the subtraction color by code raises the stakes when the child is ready to earn each color with a little math.
