Students can track which colors of the rainbow by day or week! There are three printable versions available for the day tracking sheet and for the weekly tracking sheet based on printing abilities. The bottom row of the graph is available in black and white, with the words (red, orange, yellow, green, blue, purple) typed in their respective colors, or the box filled in the respective color. I copy multiple pages and put it in a folder with prongs to make a book. My students take it out during breakfast, snack and lunch to track which colors they are eating.
