Playtime Puzzle 150 P.

The first step is to understand that puzzle pieces connect. This can be to the board or another piece. Develop spatial reasoning by learning to orientate the piece correctly 

Start with two-piece puzzles. Learn that one piece connects to another. Then progress to 4, 6, 20 and even 100 pieces!

Solve complex problems by working in three dimensions. See what fits by rotating pieces in your mind without having to place them.
