Lesson 4

Interpretemos datos de medidas que están en diagramas de puntos

Lesson Purpose

The purpose of this lesson is for students to make sense of line plots that represent measurements to the nearest half or fourth of an inch.

Lesson Narrative

In grade 2, students made line plots to show measurements to the nearest whole unit. In previous lessons, they measured objects with rulers marked with halves and fourths of an inch. In this lesson, students interpret line plots that show lengths in half inches and quarter inches and ask and answer questions about the data.
