Kassia has been a math coach (at a school not too far from me) for the past several years. She taught third and fourth graders and is, this year, teaching kindergartners. I have such respect for full-time teachers who manage to write books at the same time. I also read those books with an intense sense of belief because I know the author has lived what they are writing.
Stenhouse and Kassia have a blog tour planned to share about Math Exchanges. She will be stopping here on Thursday, October 6th. If you have any questions about this book, let me know.
Also, Kassia continues to write about her experiences teaching, and especially teaching math, at her blog.
