This product requires some teacher prep but can be used each year, so to me it was worth the minimal effort. To save on computer ink, I printed this and made copies and colored in the eggs myself. I then cut them out and laminated them. I also glued one of each size on a piece of paper and laminated it as well. These sheets were so students had a specific place to put that sized egg.
This is a great center activity and the kids loved it!
