This is another in my DTT/ABA series of lessons. Included is acquisition charts for both upper and lowercase letters as well as data sheets for keeping records for goal acquisition. Discrete Trials are highly effective for introducing and reinforcing skills for students with autism. This lesson is for Expressive letters, and is for use with verbal students. If you require a lesson for a non verbal student, please see Discrete Trial/ABA Receptive Letters with IEP Goals.
