Prof. Bill McCallum – Common Core and Illustrative Mathematics

Prof. Bill McCallum is University Distinguished Professor of Mathematics and Head of the Department of Mathematics at the University of Arizona. He is lead author of the Common Core State Standards and president of Illustrative Mathematics.

We ask Prof. McCallum about his work with Illustrative Mathematics as well as his reaction to the national controversy surrounding the Common Core Standards. What was the original intention? How can math teachers make the most of the standards in the classroom?
