Stages Learning

      Learning happens in stages. 

      Learn to crawl before you walk, learn to walk before you run.

Language development also happens in stages. Children learn to match objects first ("Put apple with apple"), then to identify objects receptively ("Give me the apple"), and finally to identify objects expressively ("What is it?" "It is an apple.").

The stages of your child's development are precious and wonderful. Stages Learning Materials will partner with you to make the most of every stage.  

Our Story

Angela Nelson, a UCLA trained ABA Therapist, founded Stages Learning in 1997 when autism diagnoses first began to rise. Our top-selling autism education product, the Language Builder Picture Cards, was designed to specifically meet the learning needs of children with autism. The research-based Language Builder Series has become a staple in home and school programs around the world and Stages Learning is now the premier developer of learning tools for children with autism.

Now headquartered in Cambridge, Massachusetts, Stages works with faculty at the Harvard Graduate School of Education, providing an incubator for graduate students who are working at the intersection of new research and learning technologies. Applying innovative research and design strategies, Angela and her team, all graduates of the Harvard Graduate School of Education's "Technology, Innovation, and Education" program, have designed new online tools for language learning, including our popular Language Builder App.

About Our Products

Our products are created to stimulate learning at each stage of language development. They feature beautiful real-photo images to capture a child's attention and engage their minds. Research demonstrates that children with autism are highly visual and literal learners, and our tools support these learning strengths. 

Our photo-based flash card sets, games, puzzles and posters offer a broad assortment of images to teach a wide range of language skills. Our card series provide opportunities to teach identical pre-language matching, categorization and learning similarities. Our work is based on 20 years of experience in helping children learn language skills and new research on digital learning technologies and instructional design also informs our tool development.

New Tools!

Stages recently launched a new product line that combines the best of traditional print with interactive iPad Apps that help preschoolers build early literacy skills. Our research-based Link4Fun interactive books and cards support language learning while providing children with engaging opportunities to improve fine motor skills and learn about the world around them.

Our recent acquisition of the popular Brain Parade “See Touch Learn” App provides us with another language learning tool to help parents, teachers, and therapists provide children with over 4,000 vivid photo-based interactive learning tools for successful language learning.
