Adding 13 Foldable Mini Book — Two-Digit Plus One Digit Facts

A 22-page foldable mini booklet for practicing +13 addition facts. +13 facts build teen place value with sums extending into the low 20s. Students decompose 13 as 10+3 as they add and tie each fact to its subtraction partner through fact families. Activities include word-problem matching, workspace word problems, a true/false equation maze, fast-fact vertical stacks, ten-frame coloring, number-line jumps, fact-family houses (addition and subtraction), number bonds, picture models, turn-around fact pairs, fact-to-sum matching, an equation search, spinner and roll-a-die practice, and color-by-code fluency. Includes answer keys for every page. Works well for math centers, small-group intervention, independent practice, and homework.
