Fraction Division Concepts and Applications

Miss Dri introduces lesson 2.5 on model fraction division, demonstrating how to use models to represent quotients. She provides examples, including dividing fractions using models and algorithms, and explains the use of fraction strips. The lesson concludes with encouragement to practice using models for better understanding.
