Every year I do a texture unit with Kindergarten. I start by using rubbing plates to show actual(tactile) & visual texture. They also make a great sound!! One of the problems I have though is the texture plates are hard to store & pass out. They are slippery little buggers!! So I finally decided the best way to do it is separate them out into gallon Ziploc/Hefty bags. This keeps the neat & organized. The students pull them out & put them back as they are using them...so they are all over the place. Today was the first time I used them...worked like a dream!
