What your child practices.
Crystal patterns climb the difficulty ladder: an AB color row, an AAB size row (small, small, BIG — wait for it), and an ABC shape row (triangle, square, circle, again). Each missing gem is found by saying the rule, then testing the choices against it.
- AB, AAB and ABC patterns
- Size sequences
- Shape cycles
- Crystal and gem vocabulary
On the sheet: Find the missing crystal in each pattern!
