Lesson 14
Representemos fracciones en un diagrama de puntos
Lesson Purpose
The purpose of this lesson is for students to make and interpret line plots displaying fractions in eighths.
Lesson Narrative
In this lesson, students use fraction arithmetic to solve problems about line plots. Students make line plots by generating data and using given data and then they solve problems about the line plots. Students have worked with these line plots in a previous course. The new part of the work in this lesson and the next is the level of complexity of the questions they answer. In this lesson they perform arithmetic with the fractions and answer questions that involve thinking about all the data as a whole and certain measurements as a fraction of that whole (MP2).
