A gold crown with red, blue and pink jewels. A page princesses and princes love to color. The picture is made of 130 squares on a 16×12 grid, and each square has a number that matches one of the 6 colors in the key: 1, yellow; 2, gold; 3, red; 4, blue; 5, pink; 6, purple.

In the math version every square gets an addition problem up to 20, and the key shows which answer belongs to which color. The picture only appears for whoever solves correctly, which turns math practice into a game.

Print it on A4 or US Letter paper and use colored pencils or fine markers. Squares that are white in the key stay uncolored. A QR code at the bottom of the sheet leads back here, for anyone who wants more pictures.

Frequently asked questions

What age is the princess crown color by number for?

It is for grades 1–2 (ages 6–8): 16×12 squares and 6 colors. There is enough detail to keep it interesting, and it can still be finished in one sitting.

How does the math version work?

Each square holds an addition problem up to 20. Solve it, find the answer in the key and color the square in that color. Every color has its own answer, and no two colors share one, so there is no guessing.

Can we color it online?

Yes. Pick a color in the key and tap the squares (on a computer you can also drag with the mouse). Made a mistake? Tap the square again to clear it, or use the eraser or Undo. The counter shows how many squares are colored correctly, and "Show the answer" shows the finished picture.

Is there an answer key?

Yes. Tick "Print an answer key too" before printing, and the colored picture prints after the coloring sheet. Handy for parents and teachers.
