Grade 3 Mathematics Module 5, Topic F, Overview

Girl in Classroom

Topic F concludes the module with comparing fractions that have the same numerator.  As they compare fractions by reasoning about their size, students understand that fractions with the same numerator and a larger denominator are actually smaller pieces of the whole (3.NF.3d).  Topic F leaves students with a new method for precisely partitioning a number line into unit fractions of any size without using a ruler.
