This is the coolest idea from my colleague, Patty. She calls them rock puzzles. It is very simple. You find nice sized, flat rocks. Wrap the rock in a towel and bam! Break a piece or two off with a hammer or another rock!





How to use the rock puzzles:

  • Put four to five “rock puzzles” together in a bag:
  • science-sensory-3
    The children have to find the rock pairs – the pieces that fit together.


So simple.  So cool!
