In this lesson, students use their understanding of and their facility with all four operations to represent and solve problems involving fractions. The last activity requires students to make sense of the problem and persevere in solving it (MP1).
- Apply operations with fractions to solve problems in a variety of situations, and explain (orally and in writing) the reasoning.
- Generate an equation to represent a situation involving fractions, and justify (orally) the operation chosen.
Let’s add, subtract, multiply, and divide fractions.
For the second activity (Pairs of Problems), plan an efficient way to assign at least 1 division problem and 1 problem involving another operation to each student (or group).
- I can use mathematical expressions to represent and solve word problems that involve fractions.
