      Module 5
Fractions as Numbers on
the Number Line

Overview

Throughout this Module, students will:
• partition different models of wholes into equal parts
• identify and count equal parts as 1 half, 1 fourth, 1 third, 1 sixth, and 1 eighth
• compare unit fractions with fraction strips
• use a number line to partition, place, count, and compare fractions
• gain awareness of equivalent fractions (i.e.. 1/2, 2/4, 3/6, and 4/8 are equivalent fractions)
• understand that whole numbers can be written as fractions
• compare fractions with the same numerator while reasoning about size
