Thanks to a tweet posted to the #SpEdChat hashtag by @Michelle_Horst on Twitter, I discovered a wonderful resource published by Crayola titled "Creative Art Experiences For Children with Special Needs". This colorful PDF document starts with a discussion on how to create an environment that encourages creative freedom. It then presents a variety of appropriate arts & crafts activities (drawing, painting, sculpting, & outdoor activities) - using Crayola products of course. There's even a highlight box all about "Painting Experiences to Offer in Inclusive Programs"!
What I like most about this resource document are the grids outlining the benefits of art exploration for children with special needs across the major areas of skill development related to art (physical, sensory, communication, cognitive, & social/emotional).
