I buy these cascade containers and never know what to do with them once they are empty. Now I do!! I love this!!
I just found this on Pinterest - Cascade Action Pacs Dishwasher Soap Print the cards of your choice. Put the cards inside the crocodile container. At circle time, say the following verse: Crocodile, crocodile down by lake, going to reach right in and see what (letter or number) you ate.
