Alligator letters/numbers jigsaw puzzle.

This puzzle made of many smaller and colorful pieces.

Older pre-schoolers will sharpen their skills by learning to look for more details in exploring where the pieces go. Are there colors that go together? Does part of the puzzle picture appear on one piece and have its match on another? Can the edges of the puzzle help give it form? These are the beginnings of developing strategies for accomplishing a task, which is a crucial part of effective learning.
