**Hints on Solving the Puzzles from ****Enchanted Learning**:

- Instead of simply crossing out a space in the table for an impossibility, put the number of the clue that gave you that information. This makes it easier to check your work if there’s a problem.
- A clue like, “Ann was not born in March,” yields one piece of information about Ann.
- A clue like, “Amy was born after Deb,” yields one piece of information about Amy and one piece of information about Deb.
