Students can match all four pieces or concentrate two pieces at a time.

Save 35%

This product is also included in a Two-Digit Addition & Subtraction BUNDLE for a savings of over 35%.

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.
