Materials:
- 1oos chart
- Unifix – enough to cover nearly every number (98 or so)
- cards with 1-100
Students start with their 100s chart covered in unifix with only a couple of numbers being showed. Each student takes it in turn to turn over a card. They must then try to take off the correct unifix block. If they get it right, they keep the unifix block. If incorrect they need to place it back.
