This is a package of 6 color readers that I use to teach my students with autism. They are each sold separately for 95 cents/piece, but they're only $5.00 for all six. These readers help students with autism learn their colors, sight words, and new vocabulary. They can be used with any young children for the same purpose. These readers can also be used to work on fine motor skills such as drawing and using scissors.
