Lesson Purpose
Lesson Narrative
In previous lessons, students used a range of skills to solve problems involving the multiplication of a whole number by a fraction. They represented situations with diagrams and expressions, and they solved problems using a variety of strategies.
In this lesson, students use their conceptual understanding to build procedural fluency with multiplication of whole numbers by fractions. Students also apply these skills to solve problems in an Info Gap activity. Students use what they know about interpreting multiplication as area to ask questions of their peers about the missing information in the problems and explain their reasoning for needing that information.
As in the previous lessons, students will encounter problems with fractions greater than 1. Students are encouraged to rewrite fractions greater than 1 as whole numbers when possible. They are not required to rewrite fractions greater than 1 as mixed numbers.
