Teacher tip
Have kids read all the clues once, then start with the clue that gives a direct yes.
How to use it
- Let kids work with a partner and explain their thinking.
- Start with an easier puzzle before the harder ones.
- Slide it into a sheet protector so kids can play again with a dry-erase marker.
Watch for
Frustration on hard puzzles. Give one clue at a time as a hint.
