Math in the Milpa
James Barta, Lucas Sánchez, Jacob Barta
Mathematics consultants from the United States provide ongoing professional development founded on the National Council of Teachers of Mathematics’ Principles and Standards for School Mathematics (2000). Consultants provide teachers with sustained, hands-on opportunities to expand their abilities to teach mathematics more effectively. Readers will learn how to create their own culturally relevant lessons, ensure that they maintain high expectations of their students, and provide students with worthwhile learning experiences.

Classroom Videos and Prospective Teachers
Kathryn Chval, John Lannin, Fran Arbaugh, Angela Bowzer
Educators who can elicit preservice teachers’ beliefs about teaching mathematics can effectively challenge and change unrealistic expectations.

Kathleen Cramer, Debra Monson, Terry Wyberg, Seth Leavitt, Stephanie Whitney
The Rational Number Project group put a twist on the familiar 10 x 10 grid in their latest curriculum development project to build meaning for decimals and improve students’ understanding of addition and subtraction with decimals.
