This document, Multiple Approaches to Teaching Subtraction of Integers [1], contains material released with last month’s conference call [2].
Page 1 and 3 have been enriched, and page 6, “Taking Away a Negative,” is a new page with a practical example highlighting the process of subtracting a negative number.
This document is a must read for all Mathnasium Instructors and Center Directors. As always, your feedback and comments are greatly appreciated.
