Fraction Concepts
Fractions in Grade 3 are a new type of number: they represent quantities that are not whole. A fraction names both how many parts and how large each part is. Three quarters means 3 parts, where each part is one quarter of the whole. The equal-parts requirement is still central, and now students meet fractions in three distinct models: region (part of a shape), set (part of a group), and linear (part of a number line). Each model reveals something different about what a fraction means.
