Fraction skills by grade

Fraction problems are practice items on one fraction skill at a time: naming fractions, finding equivalent fractions, comparing, adding and subtracting, or multiplying and dividing. This generator writes a printable set aimed at the skill and grade you name, with an answer key.

Fraction standards by grade

Each step depends on the one before, so practice on the exact sub-skill helps more than a general fraction page.

  • 3rd grade (3.NF.A): fractions as numbers, unit fractions, simple equivalents like 1/2 = 2/4

  • 4th grade (4.NF.A, 4.NF.B): equivalence, comparison, like denominators, fraction × whole number

  • 5th grade (5.NF.A, 5.NF.B): unlike denominators, multiplying fractions, unit fractions ÷ whole numbers

  • 6th grade (6.NS.A.1): dividing a fraction by a fraction

Problem types you can ask for

Name the sub-skill ('subtract mixed numbers with regrouping') and limit denominators if you like (2, 3, 4, 5, 6, 8, 10, 12, and 100 for 4th grade), or ask for a mixed review page. Sample items:

  • 3/4 + 1/6 = 11/12

  • 2 1/4 − 1 3/4 = 1/2

  • 2/3 × 9 = 6

Classroom use

Use it for intervention, review, or homework on the day's objective, then follow with the fraction word problems generator so students apply the same skill in context.

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.”

No. The output is text only, so there are no fraction bars, circles, or number lines. For 3rd and early 4th grade, have students draw the model themselves, or ask for items that describe one in words, such as 'A bar is split into 8 equal parts and 3 are shaded. What fraction is shaded?'

Yes. Ask for 'answers in simplest form' and the key shows reduced fractions, so students know to simplify.

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.
