I have 4 1-2 year olds and they LOVE this game:
You print a about 10 of each shape you can think of, cut out, and laminate. it's a lot of prep but is worth it. Then you make it snow. Throw all the shapes into the air. Have them all go and find a shape for you. Tell them what shape it is (or attempt guessing) and have them put it into a bag. They get super excited about it and will dart off to get another one. Great way to have a nice cup of coffee while fully engaging the children.
We also do this with our letters and have fun screaming out the letter sounds
