I can't take credit for these... My sister is a teacher and she has a ton of these ideas up her sleeves.
Go on a rock hunt to find a smooth, round rock. Take it home and paint (or colour) it into an Easter decoration - a bunny, a chick, an Easter egg...
Or, make Easter bookmarks. Use anything from crayons to stickers to glitter.
If you have little girls with old hairbands, add come bunny ears made out of paper and glue them on.
If you have more time. Bake some sugar cookies - add some food colouring to make them festive, shape them into eggs and throw on some sprinkles!
