This document discusses how children understand and process information in different ways. It explains that children may struggle with understanding if they have weaknesses in attention, memory, higher-order cognition, or language. Information can be processed through receptive language, non-verbal/spatial skills, concept formation, or mental representation. The document provides signs that a child may have problems with understanding in these different areas and suggests gathering information from observations, discussions with the student, and assessments to better understand the child's learning profile and challenges. Teacher strategies are recommended like presenting information in multiple ways, involving student action, and using routines.
