Homemade alphabets puzzles

I reuse some food styrofoam tray to make the alphabet puzzles for Evan to match up the big and small letters. He is learning to recognize the letters and this is one of the way to get him interest in learning.

First, I write the letters in big an small letter in one tray. Then, I cut the tray into two pieces in zig-zag way. He has to match up the letters with correct pieces.
