Participants say:

speech bubble“I’ve always wondered how to teach estimation strategies better to my students and look at the issue of teaching parts and wholes. This course has given me tons of resources to better help my students with these topics, and I have a wide array of approaches to use in doing so. It has been immensely helpful and timely.”  Dustin Grooms, Instructor, Fleming County Adult Education, KY
