Every operation, every grade

Arithmetic through algebra, grade-calibrated

Addition through long division. Fractions, decimals, percents, ratios. Pre-algebra, Algebra 1, Algebra 2, Geometry. The generator picks number ranges and complexity for the grade you name.

  • All four operations + fractions, decimals, ratios

  • Algebra 1, 2, Geometry

  • Grade 1st through college algebra

  • Drill or word-problem format

+ / −

Within 20 to multi-digit

× / ÷

Facts, long division

Fractions

Add, subtract, compare

Algebra 1 & 2

Linear, quadratic, factoring

Geometry

Area, perimeter, angles

Ratios & %

Pre-algebra range

Word problems that don't repeat

Varied contexts, every problem set

The word-problem generator varies the scenario — sports, animals, food, measurement, time — across every item so students aren't pattern-matching. Specify a context (sports, ancient Egypt, zoo) or let the generator vary.

  • Varied real-world contexts per item

  • Optional theme lock (sports, animals, food)

  • Two-step and multi-step problems

  • Balanced mix across the set

About this tool

Random Math Problem Generator — free AI generator

Sometimes you just need math problems — any math problems — calibrated to a grade, no particular topic in mind. This random math problem generator pulls from every operation, every topic, every grade level K–12 and gives you a mixed-bag worksheet in seconds. You specify the grade; it randomizes the topic mix, the operation spread, and the problem format. Perfect for substitute-teacher folders, end-of-year review, and "I just need something for bell ringers" moments. Every click is fresh. Try the generator above with "random math problems, 4th grade, 20 questions" and print a worksheet in under a minute.

What "random" really means

Random here is grade-bounded randomness. A 4th-grade random worksheet won't include logarithms, and a 1st-grade worksheet won't include long division. Within grade, the generator pulls from the Operations and Algebraic Thinking, Number and Operations, Measurement and Data, and Geometry strands in proportions that roughly match state-test weighting. You get a representative mix, not chaos.

Output controls

Specify grade (required), problem count (10, 15, 20, 30), and optionally a slant ("heavier on computation," "heavier on word problems"). You can request "mixed operations" for K–5 or "mixed strands" for 6–8. The answer key handles whatever comes out, no matter how varied the page ends up.

  • Grade-appropriate content only

  • Balanced operation and topic mix by default

  • Optional slant toward computation or application

  • Works across K–12 with the same interface

Uses

The sub-folder worksheet, the emergency bell-ringer, the end-of-year review page, the parent-asks-for-summer-practice page. Also surprisingly useful as a diagnostic — a random mixed-topic page shows you quickly where a student's gaps are. Pair with the math fact generator for fact fluency practice below the surface.

More impressive though is that it corrects student answers not simply using a pre-written answer, but by following the thought process they've pursued.

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.
