Puzzle sets include two-digit numbers 21 - 98. Only numbers with a 1-8 in the ones place are included, i.e.: no numbers with a 0 or 9 in the ones place are included (like 20 or 29). This activity is meant to develop students' ability to decompose numbers for the purpose of addition and subtraction.
Included is a recording sheet where students practice decomposing a ten and explain their process.
Simple print each puzzle piece on colored paper, laminate for durability, and cut apart.
