How to use this worksheet
- 1
On the logic grid sheet, show your child how one ✓ means ✗ everywhere else in that row and column. Once they see it, the puzzles solve themselves.
- 2
Use real objects on a coat hanger or kitchen scale before "Balance the Scales" so "equal" means the same on both sides, not "the answer comes next".
- 3
After "Follow the Arrow Code", let your child write arrow directions for you to follow around the room. Giving exact instructions is harder than following them.
