A superficial reading of the Common Core State Standards for Mathematics might seem to indicate that standard algorithms are not taught until Grade 4.

In order to avoid confusion, please read this discussion with Bill McCallum, one of the authors of the standards, on his Tools for the Common Core site.

Dr. McCallum’s comments are a good reminder that standards are not curriculum, and that students must move along learning progressions and be exposed to concepts when they are ready.
