Unit 5, Lesson 12
Fracciones equivalentes en una recta numérica
Grado 3
Preparation
Lesson Narrative
In previous lessons, students learned that two fractions are equivalent if they are the same size. In this lesson, students work with situations that involve lengths to build their understanding that fractions at the same location on a number line are equivalent. Number lines are provided to ensure that students, who choose to use two number lines to demonstrate equivalence, work with the same length interval for 1 unit.
- Engagement
- MLR8
- Comprehend (in spoken and written language) the meaning of the term “equivalent fractions.”
- Generate (orally and in writing) equivalent fractions.
- Use a number line to justify (orally and in writing) that two or more fractions are equivalent.
- Encontremos fracciones que están en la misma ubicación.
Required Materials
Activity 3
Required Preparation
- Each group of 2 students needs 6 number cubes.
Teacher Reflection Questions
In this lesson, students use number lines to show that fractions are equivalent. How did their previous work with diagrams and fraction strips prepare them to do this?
