We will present the Action-Consequence-Reflection (ACR) paradigm for using computer algebra didactically. First, examples of available documents for both hand-held and desktop computer algebra systems will be shown along with methods for their use in the classroom. Second, we will illustrate how easy it now is to make ACR documents with a TI- Nspire CAS and Maple 13. Our sample ACR documents will be chosen from topics relevant to precalculus up to real and complex analysis. We'll end the session with a discussion of classroom uses of ACR documents.
