Addition and Subtraction Within 10 Mystery Pictures

Every number stays at 10 or below, with problems such as 4 + 5, 10 − 3 or 2 + 6. That covers the facts children need to know by heart before anything bigger: number bonds to 10 (7 + 3, 6 + 4), adding and taking away 1 or 2, and simple subtraction from 10. Because each answer is also a row number, the child has to read the result carefully and find the matching line, which quietly reinforces number order.

The sheet uses the coordinates format: next to each problem is a letter, as in 4 + 5 = C ___. The answer 9 is the row and C is the column, so the child colors square C9 in the color named above that group of problems. For beginners, pick a small picture (about 40 problems) on a single page and move to medium once they are fluent. In class, the five-variant option gives each child a different set of problems for the same picture, so copying a neighbor does not help.

Let children use fingers or a number line at first; the picture checks the work anyway. If one spot of the finished picture looks wrong, the answer key shows which square should have been colored, so you can revisit that single problem together instead of redoing the page.
