oh.my. I have been having way too much fun with making sensory trays to go with our "letter of the week". So be prepared for more! Many, many more! And here is a little note on sensory trays, their educational value, and where to get started. They provide a lot of experimenting and creative play with new textures and mediums. Some people keep them out or ready to go for long periods, I usually just do 1-2 a week and save the items for something else later. :) Fun.fun.FUN!
