Here's an easy colour sorting activity for you guys to do with your little monsters!
I used strips of construction paper to make a "frame" on contact paper. I gave the monster some left over seasonal foam shapes to sort... which are removable so I would recommend them over pieces of paper! She was a little confused at first because usually when we do contact paper activities it's a free for all and there is no real "goal"! But she got the hang of it pretty quickly and accomplished her task over a few days!
