My son is having trouble with his prepositions. So I created a game for him. This is similar to the games used in a speech or OT therapy setting and would be good for a child with Autism or PPD. I laminated images of lilly pads and attached them with velcro dots to clear plastic cups (so that I could demonstrate "under"). I purchased a set of cheap frogs to use as manipulatables. I created cue cards that show the frogs in various positions with the lilly pads. You can see a photo of the finished product above. Because not everyone will have access to the same frogs, I've included pictures of the frogs that can be used instead. If you are using pictures of the frogs you won't need the cups. But, I still recommend laminating the images.
