Exploring Concept Development in Eureka Math Grade 3

Mrs. Walker's lesson focuses on understanding division through the use of arrays and its relationship with multiplication. The lesson begins with solving a division problem using arrays, explaining the concept of quotients, and relating division to array models. It further explores the relationship between multiplication and division, emphasizing the importance of understanding how these operations are interconnected. The lesson concludes with practical exercises to reinforce the concepts learned.
