Math practice by skill and grade
Every skill in Num Drill has six difficulty levels, pitched 2–3 grades ahead of typical pacing for kids who want a real challenge. Below is the full menu by skill; further down, the same content organized by grade for parents and teachers who want to match practice to where their child is in school.
Quick start
Not sure where to start? A 10-question multiplication quiz at level 3 is the most common entry point for 3rd–5th graders. Takes about a minute.

Addition & subtraction practice
Single-digit fact fluency through 4-digit arithmetic with regrouping. The earliest skills work for kindergartners; the upper levels match end-of-4th-grade standards. Best for kids building automaticity with the basics.
Multiplication practice
From 1–5 facts up through 3-digit × 1-digit. Levels 2–3 are the classic times-tables target for end-of-3rd / mid-4th grade; levels 4–6 push into multi-digit work for 4th–6th graders.
Division practice
Division facts at levels 1–3 (closely paired with multiplication facts), then long division of 2- and 3-digit dividends at levels 4–6. Best for 3rd–6th graders building real division fluency.
Fractions practice
Six progressive levels covering single-fraction comparison, like denominators, unlike denominators, mixed numbers, and full four-operation fractions arithmetic. Best for 3rd–6th graders.
Percentages
Three question kinds (part of, percent of, find the whole) with integer answers across six levels. Aligned to the Common Core introduction of percentages in 6th grade, with simpler levels for 5th-grade enrichment. Practice percentages directly in the app.
Pre-algebra (solve for x)
One-step and two-step linear equations with integer solutions, including negative numbers at higher levels. Best for 6th–7th graders or advanced 5th graders working ahead.
Math fact fluency
A focused entry point for the four basic operations — addition, subtraction, multiplication, division — aimed at instant recall. The single best place to start if your child is in grades 1–4 and math facts are the bottleneck slowing down the rest of math.
Practice by grade
1st & 2nd grade (ages 6–8)
Single-digit and 2-digit addition and subtraction drills are the right fit. Aim for 5 minutes a day, most days. The math fact fluency page has a focused 4-week routine for building automaticity.
3rd grade (ages 8–9)
The big year for multiplication facts and the start of division and fractions. Most 3rd graders start with multiplication level 1 or 2 and division level 1.
4th grade (ages 9–10)
Full 1–12 multiplication tables, multi-digit addition and subtraction, long division, and serious fractions work begin in earnest.
5th & 6th grade (ages 10–12)
Multi-digit multiplication and division, full fractions arithmetic, percentages, and pre-algebra. Most 6th graders working through Num Drill's harder levels are practicing skills that show up on standardized tests in 6th and 7th grade.
Why practice with Num Drill
Free, no-login, no-ads, no in-app purchases. Profiles live on the device and never sync to a server. Sessions are short by design — a 10- question quiz takes about a minute — because retrieval practice and spacing work best in small daily doses, not long single sessions. See the methodology page for the research that backs this approach.
