Grade 4
Indiana Math Standard: 4.NS.3
Use fraction models to represent two equivalent fractions with attention to how the number and size of the parts differ even though the fractions themselves are the same size. Use this principle to generate equivalent fractions.

Writing A Story About Fraction Equivalence
When fractions take on a new denominator, it’s as if they’re wearing a disguise – same value, new look. So let’s write a story about fraction equivalence starring a fraction who needs to fit in with a new group.
A Grid-Based Fraction Project
You’ve got 60 spaces on a grid to create an amusement park, a house, a farm, or whatever you’d like. Divide it into seven pieces, order it by size, combine into two halves, and more in this fraction project.
