I found this website where you can play Easter games (if the internet works...)

And this Egg hunt (I'm gonna do it with 3rd and 4th):

Find the Egg

Bring in a hard-boiled egg to class or make an egg from card. Ask one child to leave the room. Hide the egg in the classroom and then invite the child back into the room. The children in the classroom help the child find the egg by ‘clucking’ like chickens. If they cluck quietly the child is far away from the egg. If the cluck loudly, the child is near the egg. Repeat with other children.

Happy Easter!!

I had a look at the web, it looks like fun. ( I got a 47 score in the memory game when trying it, by the way). Did the students like it? Thanks for sharing!
