What you just did
Match-to-sample is one of the most studied procedures in the experimental analysis of behavior, and a well-documented way to teach a child that two things belong together — and the foundation on which words, categories and comprehension are built. Interlaza runs it with errorless prompting, mastery tracking for every concept, and a curriculum that reorganises itself when a child stalls.
