What a fraction word problem asks

A fraction word problem puts fraction arithmetic inside a story, so students first decide which operation the story calls for, then work with the denominators: 'Ella ate 3/8 of a pie and her brother ate 1/4 of it. How much is left?' (3/8). This generator writes sets for grades 4-6 with an answer key.

What the standards expect

Each grade adds operations to the stories:

  • 4.NF.B.3d: add and subtract fractions with like denominators in word problems

  • 4.NF.B.4c: multiply a fraction by a whole number in context

  • 5.NF.A.2: unlike denominators

  • 5.NF.B.6 and 5.NF.B.7c: multiplying fractions and dividing unit fractions in real-world problems

  • 6.NS.A.1: dividing a fraction by a fraction in context

How difficulty changes by grade

Ask for one operation or a mix of part-of-a-whole, compare, and fraction-of-a-set stories. Difficulty follows the grade:

  • 4th grade: like denominators, such as running 5/8 mile and walking 2/8 mile

  • 5th grade: unlike denominators and fraction of a set ('2/3 of 15 students', answer 10)

  • 6th grade: dividing fractions ('How many 1/4-cup servings in 2/3 cup?', answer 2 2/3)

How to use them

Use them as the second half of a lesson: procedural practice with the fraction problems generator first, then word problems to see who can transfer the skill.

How the math problem generator works

  1. 1

    Describe the set

    The topic and the format, such as two-step equations or fraction word problems about cooking.

  2. 2

    Set the details

    Grade, difficulty, and number of problems. It usually takes 10 to 20 seconds.

  3. 3

    Check and print

    Work a few problems yourself, then print the student copy and the answer key.

What teachers say

Teachers across subjects, from AP history to astrophysics, on grading with GradeWithAI.

“I've really enjoyed using the GradeWithAI program. It saves me a ton of time, especially when I have class sizes of 35 or 36 students times five.”

“GradeWithAI doesn't just grade. It gives the student reasoning as to why every point is awarded or not awarded. That is a very valuable thing for the students.”

Math problem generator FAQ

Questions about this tool? Email john@gradewithai.com.

Yes. Ask for 'fraction word problems, subtraction only' (or addition, multiplication, or division) and every story uses that operation.

Yes. Ask for denominators up to 12, or name them ('halves, fourths, and eighths only'), and the generator keeps to those.

Addition, subtraction, multiplication, division (including long division), fractions, decimals, ratios, percents, pre-algebra, Algebra 1 and 2, and geometry.

Yes. Ask for word problems in the description, and add a context such as sports, animals, or food if you like.

Pick the grade, which sets the kind of numbers and operations, then choose easy, medium, or hard.

Yes. Every problem has an answer, printed on a separate page. Work a few problems yourself before handing the set out, since AI-generated math can contain mistakes.

No. It writes problems. To grade completed work, upload it to GradeWithAI, which reads handwritten math and gives partial credit under your rubric or answer key.
