BUT AFTER this there was no longer a problem! My kiddos had a blast.
How to: I printed off a pair of either synonyms or antonyms on labels and stuck them to a plastic egg. I put Scotch tape over the label so it would last longer. The kids got into partners and labeled a half sheet of paper 1-23...(that's how many eggs I made...random number but who cares?)
And I made the mistake of throwing a couple of eggs under this pointy plant. One of my kiddos got poked. I couldn't help giggle because he ran up on the egg with so much excitement. He just didn't see the "pokey things" as he called it.
