Math for 9-Year-Olds: Free Printable Fourth Grade Worksheets
Nine-year-olds are generally in fourth grade, where the arithmetic stakes go up. Fourth graders are expected to multiply multi-digit numbers (two-digit × two-digit, three-digit × one-digit), start long division, and deepen their understanding of fractions beyond 'parts of a whole'. This worksheet generator is preset to hard multiplication (two-digit × one-digit) — a good starting point. Once that feels comfortable, switch to long division at its easy level, then to fractions. At this age, most kids can sit for fifteen or twenty minutes of math if the problems feel achievable. If your child is hitting a wall, drop back one difficulty level rather than push through — small wins build the stamina they'll need for fifth grade.

How to use this worksheet with a 9-year-old
Start with multiplication, hard
Hard means 2-digit × 1-digit — the first step into multi-digit multiplication. Make sure your child knows their times tables before starting.
Graduate to advanced (2-digit × 2-digit)
Once hard feels routine, move to advanced. Show the standard algorithm step by step — this is a new skill, not just faster computation.
Try easy long division
Switch to long division at easy difficulty (2-digit ÷ 1-digit). This is often the hardest skill of fourth grade; go slow.
Use fractions for variety
Fourth grade is where fractions become serious. Switch to fractions every week or so to build a feel for equivalent and unlike denominators.
Frequently asked questions
What math should a 9-year-old know?
Fourth graders should have times tables fluent to 12×12, multiply multi-digit numbers, divide up to four-digit numbers by one-digit divisors, understand and compare fractions with unlike denominators, add and subtract fractions with like denominators, find factors and multiples, measure angles, and solve multi-step word problems. Place value extends to 1,000,000.
What's the hardest part of fourth grade math?
For most kids, long division. It demands fluent times tables, subtraction, place-value reasoning, and the patience to work through a multi-step algorithm. Expect it to take weeks to click — that's normal, not a sign something is wrong.
How do I teach fractions to a 9-year-old?
Start physical. Cut an apple, pizza, or piece of paper into halves, quarters, thirds. Compare sizes. Then move to the written notation. The biggest misconception at this age is that a bigger denominator means a bigger fraction — show 1/8 vs 1/4 on paper and let them see why that's wrong.
My 9-year-old can multiply but can't divide. Why?
Division is harder because it has more moving parts and doesn't have a single answer you can just 'see'. Kids who struggle with division almost always have a gap in their times tables — if you don't instantly know 7 × 8, you can't tell that 56 ÷ 7 is 8. Shore up the multiplication facts first.
How long should a fourth grader practice math daily?
Fifteen to twenty minutes of focused practice at home, on top of whatever they're doing at school. Quality matters more than quantity — one focused sheet a day is better than five rushed ones.
