Part-Part-Whole Prickly Problems
These fun and engaging one-page games are an easy, no prep resource that can be used in any middle school classroom. Students must roll the dice, solve the unknowns and find their answer in the centre grid to claim it as their own.
The game can end in the following ways:
- Play for a specific amount of time. The person with the most counters on the centre grid, after this time frame, wins.
- Play until one person gets three counters in a row, either horizontally, vertically or diagonally.
- Play until all squares on the board are covered! Whoever has the most counters covering the squares is the winner!
For formative assessment purposes, students can record their responses on the recording sheet.
The perfect game for numeracy rotations and fast finishers. Simply print and play!
