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.

About this tool
4th Grade Math Problems — free AI generator
Fourth grade is the multi-digit fluency year and the start of serious fraction work. By June, a 4th-grader needs to multiply 4-digit by 1-digit numbers and 2-digit by 2-digit fluently, divide 4-digit by 1-digit numbers, add and subtract fractions with like denominators, multiply fractions by whole numbers, and convert across measurement units within a system. The 4th grade math problems generator above produces calibrated practice for the full Common Core 4.OA, 4.NBT, 4.NF, and 4.MD scope. Pick the standard cluster, set the difficulty, and generate 10-20 print-ready problems with worked-solution answer keys.
What 4th grade rigor demands from a math problem
The cognitive jump in 4th grade is from single-step thinking to multi-step thinking. A 3rd-grade problem reads 'A box has 6 rows of 4 cookies. How many cookies?' A 4th-grade problem reads 'A box has 6 rows of 4 cookies. The class has 27 students. If everyone gets one cookie, how many will be left?' The second requires interpreting the situation, executing two operations in the right order, and reasoning about whether the answer makes sense. The generator above produces problems calibrated for that multi-step demand — single-step computation drill is available when fluency is the goal, but multi-step word problems become the default for word-problem requests.
Multi-digit multiplication (up to 4-digit by 1-digit, and 2-digit by 2-digit)
Multi-digit division using place value strategies and area models
Fraction equivalence, addition/subtraction with like denominators, multiplication by whole numbers
Multi-step word problems requiring 2-3 sub-tasks per item
The 4th grade Common Core scope the generator covers
Operations & Algebraic Thinking (4.OA): multi-step word problems with the four operations, factors and multiples, prime/composite numbers, generating numerical patterns. Number & Operations in Base Ten (4.NBT): place value to 1,000,000, rounding multi-digit numbers, fluent multi-digit addition/subtraction, multi-digit multiplication and division strategies. Number & Operations - Fractions (4.NF): equivalent fractions, comparing fractions, decomposing fractions into unit fractions, fraction operations with like denominators, multiplication of fractions by whole numbers, decimal notation for fractions with denominators 10 and 100. Measurement & Data (4.MD): unit conversions within a measurement system, problems involving area and perimeter, line plots with fraction units, angle measurement and addition. Geometry (4.G): drawing and identifying lines, classifying figures, lines of symmetry.
Multi-step word problems are the year's hardest skill
Most 4th-grade students compute well by mid-year — what they struggle with is interpreting situations that require multiple operations. The CCSS 4.OA.3 standard requires students to 'solve multi-step word problems using the four operations, including problems in which remainders must be interpreted.' Generate dedicated multi-step practice weekly and walk through the four-stage problem-solving routine: understand the situation, choose the operations, execute computation, check whether the answer makes sense in context. The generator above includes worked-solution answer keys that model that routine so students see the reasoning, not just the final number.

Hear from teachers who are saving time and providing better feedback.
“For Chadwick users, GradeWithAI has improved feedback efficiency and effectiveness, as it is grounded in existing platforms and is highly adaptable.”
“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.”
“GradeWithAI [provides] students with timely individualized feedback on their homework assignments and formative assessments. This is a job that is virtually impossible for a teacher to do on a regular basis.”
“Students have also appreciated the consistency and immediacy of the feedback I can provide through GradeWithAI. This has enabled them to make necessary corrections and achieve their desired scores on any assignment.”

The 4.OA.3 remainder-interpretation standard requires students to reason about what to do with the remainder in division word problems (round up, drop, or use as a fraction). The generator produces problems that explicitly require this interpretation — request 'division word problems with remainders, 4th grade, mixed interpretation types'.
