The final report of the National Mathematics Advisory Panel paid close attention to “proficiency with fractions…for such proficiency is foundational for algebra and, at the present time, seems to be severely underdeveloped.” This webcast, broadcast in September 2008, showcases best practices when it comes to the teaching of fractions. How do teachers and school district personnel ensure deep “conceptual and procedural knowledge of fractions,” as stated by the national math panel report? The webcast features videotaped segments from Dr. Hung-Hsi Wu’s Mathematics Professional Development Institute – the famous “Wu Institute” – an intensive three-week summer course that addresses the mathematics needed for teaching number sense in K-7 classrooms. Also featured are Dr. Denise Mewborn’s work at the University of Georgia and Patti Huberty’s teaching at Colbert Elementary School in Colbert, GA.
