Unit 5, Lesson 2
Name Parts as Fractions
Grade 3
Preparation
Lesson Narrative
Previously, students partitioned rectangles that each represented 1, by folding them into fractional parts. Now students draw lines to partition a shape and use the fraction notation they learned to label each part as a unit fraction and to describe a shaded part as a unit fraction. This lesson is the first time that students work with fraction strips, which will be used multiple times in the unit.
- Engagement
- MLR8
- Comprehend (in spoken and written language) the meaning of the term “fraction,” and that the notation can be used to represent unit fractions.
- Draw and label to partition shapes into halves, thirds, fourths, sixths, and eighths. Express the size of each part as a unit fraction of the whole.
Required Preparation
- Use the blackline master to create one set of 6 equal-size strips for each student. Students will use these strips again in Section C.
