Colour by Code Worksheets for Addition Facts

Addition fact fluency is practiced through a set of colour-by-code pages where each cell contains an addition problem instead of a plain number, and students must solve it before matching the sum to a colour key (for example, red for 6, blue for 11, pink for 15, green for 5) printed at the bottom of the page. The problems progress across the set from very simple sums like 0+15 up to two-digit totals such as 19+1 and 16+4, so the difficulty increases as students move through the pages. Each page repeats the same colour-by-code format with a fresh grid of problems and a new colour key, letting the resource be used for repeated independent practice or as a math centre activity. There is no separate answer key; the colour key itself lets students self-check as they work, since a wrong sum will produce a colour that does not match the intended picture. Students who need a strategy for solving these facts rather than memorizing them outright can build that foundation first with make a ten strategy worksheets.
