In this lesson, students will rely on models and reason about the size of the product to the size of the factors used in the problem. When multiplying by mixed numbers, the product will not always be larger than the factors. Products, when multiplying fractions, will look different than the products when multiplying whole numbers.How can we use models to compare the size of a product to a size of a factor in mixed numbers?Each Cohesion Education video has been designed by teachers for parents!
