Unit 3, Lesson 5
Multipliquemos una fracción unitaria por una fracción no unitaria
Grado 5
Preparation
Lesson Narrative
While the previous lesson used a context to help visualize fractions and their product, in this lesson the fractions are more complex. There is no context so students can focus on how the diagrams and expressions relate to the value of the product. In this lesson, students also begin to work with side lengths that are fractions greater than 1. Students also practice estimating areas of rectangles where the side lengths are not shown.
