Sponges! I got 2 packs at the dollar store. That is 20 sponges for $2.00. I put them in a basket we already had. We have been using them to toss, stack, sort, build tall buildings, hide and they even stick to our felt board. My children have already got $2.00 worth of fun out of them. I hope they can keep her busy so I can teach DS school. I am making up a bunch of what I call busy boxes to keep her busy, happy, and quiet during school time. She loves to SCREAM when she is happy or sad. Her screams do a number on our school time. I will let you know how this works out. I know other people homeschool with a little one. I just need to find out how they do it.
