We decided to assign pineapple to joy because, well, what else do you think of when you see a pineapple? :)
This activity is a simple one.
1. Print off one of the two pineapple templates I made.
2. Buy a pack of yellow sponges from the dollar store (each pineapple used about 1.5 sponges). Cut them into squares and let the sponges dry out overnight (they'll be a bit damp right out of the package).
3. Give your kids the sponges, some glue, the pineapple printout, a green crayon, and let them go to town!
