The professional development videotape collection for teachers of grades K-2 draws from Kathy Richardson�s expertise in working with teachers on long-term projects aimed to improve teaching and learning of mathematics. The videotapes and guides help teachers and leaders:

• identify important mathematical concepts,
• deepen teacher�s mathematical understanding of the concepts they teach,
• learn how children�s mathematical thinking develops,
• assess mathematical understanding and adjust teaching practices to meet children�s needs, and
• learn ways to organize classrooms to maximize success for all students.

The collection includes videos that focus on different aspects of student�s mathematical performances and support for teachers to deepen students� understanding. Videos include: A Look at Children�s Thinking, The Learning Environment, Thinking with Numbers: Number Talks, Making it Work in Your Classroom.
