Megan, as full inclusion is being imlimented, as it should , we all have a collection of varied IEP students. They should- due to the fun and repetitive built in success of WBT do just fine. My suggestion would be try it "normally" if there is such a thing in teaching. Then try a three some where they can have more models, use them as your helpers to demonstrate, do a big switch where they get to move to a new partner, and use a leader to be there personal assistant for just one day. Did this help any? Stay positive:-)
