Unit 6, Lesson 7
Multi-step Conversion Problems: Customary Lengths
Grade 5
Preparation
Lesson Narrative
In this lesson, students solve multi-step conversion problems with standard length units. These conversions can be more challenging because they involve multiplying by numbers other than 10 and powers of 10. This means that students will use the skills they developed in previous units, where they learned to multiply whole numbers and fractions. Students continue to work with whole numbers and fractions and to think strategically about whether to convert from the larger unit to the smaller unit or from the smaller unit to the larger unit.
- Engagement
- MLR8
- Explain (orally and in writing) strategies for solving problems that require the conversion of customary units of length.
- Let’s solve multi-step problems about customary length.
Required Materials
Activity 1
Required Preparation
- Create a set of cards from the blackline master for each group of 2.
- Before the lesson, figure out a location, with which students are familiar, that is about 1 mile away from the school. You will share this location in the Launch to help students understand the length of 1 mile.
Teacher Reflection Questions
When students were sorting the lengths, what question did you ask to help students make connections?
