Division Strategies and Concepts

Mrs. Le Moine introduces a lesson on partial quotients for fifth graders. The lesson explores different strategies used by Claire and Jada to solve division problems using multiplication and subtraction. Students engage in an activity involving division expressions and card matching to find sums equal to a given quotient. The video concludes with practice problems to reinforce the concept of partial quotients.
