I had tons of plastic eggs at my house so I made an easy do-with-every-group game out of them. I sorted the eggs and assigned a speech sound/skill to each color. I stuffed the eggs with words/directions and bam! Done! I used this activity with every group, grades K-5 for the whole day and everyone loved it.
I had originally planned on surprising students by filling some of the eggs with jellybeans. This caused them to shake each egg wildly before opening it. Jellybeans went flying. I hid the jellybeans after then first session.
This turned out to be super fun (flying jelly beans and all) and was so easy!!
