Teacher's field guide
What This Cluster Means
What Students Need to Do
- Students solve story problems by adding, subtracting, comparing, or finding equivalent fractions. They use fraction strips, number lines, or area models to show how the quantities relate.
What Mastery Looks Like
- Students choose a useful model, such as fraction strips or an area model. They find equivalent fractions, solve accurately, and explain comparisons or answers using the problem context.
Common Misconceptions
- Students may add or subtract both numerators and denominators. They may compare fractions by looking only at the denominator or assume unlike denominators cannot represent equal amounts.
How to Assess It
- Give this exit ticket: “Maya ate 3/8 of a pizza and Luis ate 1/4. Who ate more, and how much more?” Require a labeled model and equation.
Lesson moves
Ways to Teach It
Give pairs fraction strips to model 1/3 + 1/4, then record an equation and explain how the model shows the sum.
Ask students to write and defend an answer: Which is greater, 5/6 or 7/8, and how does a model prove it?
Play Fraction Match with cards showing fractions, equivalent forms, and visual models; students collect sets of three matching representations.
Use grocery sale signs marked 1/2 off, 1/4 off, and 3/10 off; students compare discounts and explain which saves more.
