How to teach it
- Solve the fact in a square.
- Find the answer in the color code and color the square.
- When every square is done, the picture appears. A square that looks wrong is a fact to check again.
Questions teachers ask
- Do the pages need a color printer?
- No. The student page prints in black and white: the color code names each color in words. Only the answer key shows the finished picture in color.
- What are color-by-number math pages good for?
- Fact practice that checks itself. They suit early finishers, centers and review days, after the facts have been taught.
