Horizontal puzzles are all the rage these days, didn't you know?
Step 1: Find a piece of paper any size (I used 12x12 scrap paper) and draw a picture on it.
Step 2: Cut the picture into horizontal strips about 1/2 inch wide.
Step 3: Shuffle the strips so they don't stay in order, then hand them over to your child to put back together.
Make a few, they're easy and fun.
