New to my store as of 12-20-13, this FREE Common Core aligned resource was developed to provide students with practice finding 10 more or 10 less than a given 2-digit number. Students answer the questions “What number is10 more?” and “What number is 10 less?” These two-piece puzzles are complete when students correctly count the pictorial representation (shown using base 10 blocks) on the left half of the puzzle and match each to the corresponding number that answers the question on the right half. A page of puzzle solutions is included. The “number” part of each puzzle is presented in a large, bold, colorful font. A tens and ones work mat is included for students using concrete materials. A printable recording sheet and an answer key are also included.
