Much of what I have learned about curriculum development is incorporated in these units. For example, do not be afraid of repetition. It is critical that students with significant disabilities get to experience material over several days to be able to assimilate what is being taught. Also, adding visual supports to your printables and class activities helps students pay more attention to the content you are presenting rather than the mechanics of what is expected. Finally, ask questions. Good questions!! Regardless of the material, we can ask students questions that will push them to think more deeply than before.
