Dividing Fractions and Understanding Models

This video tutorial by Mrs. Laus covers module two, lesson three on dividing fractions by fractions. It begins with a review of previous lessons on dividing fractions by whole numbers and vice versa. The tutorial uses models to demonstrate division of fractions, emphasizing the importance of common denominators. Various examples are provided to illustrate the process, including complex problems. The video concludes with a discussion on scaling and its effect on division, followed by practice problems to reinforce learning.
