Simply print each puzzle piece on colored paper, laminate for durability, and cut apart. I encourage students to use whiteboard markers on some pieces. If laminated, the whiteboard marker ink wipes off easily.
NBT 2 – Add Three-Digit Numbers
Three-Digit Addition Number Puzzles are a set of four-piece puzzles that develop students’ fluency and mental math strategies for three-digit addition.
The puzzles are built with four models and strategies: The expression, a number line, base-10 blocks, and breaking apart the addends by place value. The answer is displayed in the middle of the puzzle. Each piece requires students to figure out the answer using the strategy or model and does not reveal the answer without some work. Students can match all four pieces or concentrate two pieces at a time.

This definitely took some time to cut out, laminate and cut out again due to the nature of the "puzzle piece" design. However, the kids enjoyed using these task cards!
