Color-by-number pages ask a child to match a number to a color and stay inside a small square: a quiet workout for number recognition, focus and pencil control. Math mode adds a real payoff for practicing facts — the picture only appears when the answers are right, so kids check their own work without being told to. Change the grid size to match the age, swap any of the six colors, add a name for a personal page, and shuffle to get a new set of problems for every student.

Choose a picture, a grid size and six colors. Every cell shows a number (or a math problem in Math mode); the color key at the bottom of the page says which color each number stands for. Press Print — the colored answer key prints as a second page.
In Math mode every cell shows a small problem instead of a number: addition to 10, subtraction within 20, multiplication facts to 10 × 10, or a mix of addition and subtraction. The child solves it, finds the answer in the key and colors the cell. The picture appears only when the sums are right.
A 10–12 grid has big cells that suit preschool and kindergarten. 14–18 works for grades 1–3, and 20–24 makes a fine-grained page for older kids. For Math mode, 12–16 keeps the problems easy to read.
Mandala mode draws a numbered radial design with rings and wedges instead of a pixel picture. The symmetry rule changes with every shuffle, so each mandala is different.
