DTT Letters

How can this app help you?

Dr. Gary Brown’s Autism/DTT Letters app uses Discrete Trial Training (DTT) to help your child learn the letters of the alphabet (A-Z) and to learn the difference between uppercase and lowercaseletters. The letters can be viewed in a simple sans-serif font, serif font, handwritten print font or a cursive font.

DTT is not a children’s game. It is a therapy based on years of scientific research. DTT is the primary teaching method used in Applied Behavior Analysis (ABA) to teach numerous pre-academic and social skills to children with autism. This app can be used to help teach the letters of the alphabet to children with autism, attention deficit disorder (ADD), attention deficit hyperactive disorder (ADHD), or any child who has trouble staying on task.
