Lesson 7

Fracciones no unitarias en la recta numérica

Lesson Purpose

The purpose of this lesson is for students to locate non-unit fractions on the number line.

Lesson Narrative

Previously, students built non-unit fractions from unit fractions with diagrams and fraction strips. Now, students deepen their understanding of fractions on the number line as they locate and label non-unit fractions. Students also discuss how they know when fractions are less than 1 or greater than 1 and are introduced to the terminology numerator and denominator.
