Understanding Fractions and Models

This video tutorial is part of a professional learning session focused on teaching fractions using manipulatives and strategies. It covers three types of fraction models: set, length, and area models, providing examples and strategies for multiplication and division of fractions. The session emphasizes the importance of understanding the whole and parts in fraction problems and encourages flexible use of manipulatives. It also discusses teaching strategies, differentiation, and community resources for educators.
