Fraction Word Problems: Bar Models

Adding and subtracting fractions word problems solved with bar models, so students see why unlike denominators need a common unit before they compute. Each problem pairs a short story with two stacked fraction bars, a shading task, and a scaffolded equation that walks from the original fractions to equivalent fractions to the answer.

What's inside (1 student page, 2 problems)

• Add with bar models: Maya runs 1/2 mile before school and 1/3 mile after. Students compare the 1/2 and 1/3 bars, shade the total in sixths, and complete 1/2 + 1/3 = ?/6 + ?/6 = ?/6 mile.
• Subtract with bar models: A jar holds 3/4 cup of juice and Sam drinks 1/2 cup. Students shade what is left and complete 3/4 − 1/2 = ?/4 − ?/4 = ?/4 cup.

Standards: CCSS 5.NF.A.1 (add and subtract fractions with unlike denominators by replacing them with equivalent fractions) and CCSS 5.NF.A.2 (solve word problems involving addition and subtraction of fractions using visual fraction models).

Why teachers love it: The bar model makes the common denominator visible instead of procedural, the fill-in equation keeps the steps in order, and the real-world units (miles, cups) keep the answers meaningful. Works as guided practice, a math center, or an exit ticket. Print-and-go.
