A fundamental task in middle school computation, subtracting decimals can be a bit of a challenge. Having a self-checking activity can help to build confidence as students work to master their skills. Students will subtract positive decimals and match problems with their solutions to create this 4x4 puzzle.
This activity requires NO teacher prep!!!
Download includes THREE versions for instant differentiation for average learners, those still struggling with their skill, and those in need of a bit of a challenge!
This self-checking activity both strengthens essential computation and pre-algebra skills and reinforces logical thinking and problem solving skills.
Students simply cut out the 16 pieces and start solving. I have my students glue their finished puzzle down onto a piece of construction paper but it could be printed on card stock, cut out, and laminated for a station activity that will last year after year.
The best strategy for solving is to take one center piece (no blank edges), solve one of the two problems on it, and match up its answer. Continue to build off the central puzzle matching problems and answers until its completion. Students will be tempted to just make matched pairs (which is fine) but it does seem to take longer to piece it all together when they do it that way.
