This whole class topic needs equipment and often lots of spare copies of the worksheets.
Additionally,
- photocopying on to card - might help
- a small screwdriver to tighten the compasses - can be a good idea
- having small bits of card and sellotaping them at the back of the paper, where the compass point has made a "too large hole" can rescue students from "starting again"
