I made a weather/calendar board for A17 using familar boardmaker pictures. I used a cheap clipboard from the dollar store. I used a clipboard instead of cardstock so it would be sturdy when trying to velcro the picture. For other boards I have used inexpensive white boards to velcro pictures.
He picks from a choice of 2 or 3 pictures when we do the board. For the I am statement, this means describe how I am feeling. This is a tough concept for many kids with special needs. For seasons, we also have an interactive book where he needs to put pictures under the proper season.
