Unit 5, Lesson 13
Números enteros y fracciones
Grado 3
Preparation
Lesson Purpose
The purpose of this lesson is for students to recognize fractions that are equivalent to whole numbers and write whole numbers as fractions.
Lesson Narrative
In previous lessons, students noticed fractions at the same locations as whole numbers on the number line. In this lesson, students develop more fully the idea that whole numbers can be written as fractions and learn to recognize fractions that are equivalent to whole numbers. Students encounter and make sense of fractions with 1 as the denominator.
Students use their knowledge of parts and wholes, and the patterns they observed on number lines, to express the numbers 1, 2, and 3 as fractions. They then extend the patterns they observed to express larger whole numbers as fractions.
This lesson has a Student Section Summary.
