Num Drill for parents and homeschoolers

What it is, who it’s for, what data it collects (almost none), and how to fit it into a normal week.

What Num Drill is

Num Drill is a free, no-login math practice tool focused on arithmetic fluency for kids in roughly grades 2–6. It covers seven operations — addition, subtraction, multiplication, division, percentages, pre-algebra, and fractions — each with six progressive difficulty levels pitched a couple of grades ahead of typical curriculum pacing. The product is intentionally narrow: it doesn’t teach concepts, it drills facts so they become automatic.

Who it’s for

Num Drill is built for kids who are ready for repetition: kids who’ve been introduced to multiplication and want to get faster, kids working a grade or two ahead and looking for challenge, kids preparing for tests like AMC 8 or state assessments, and homeschool families who want a no-friction practice surface that doesn’t require an account.

It’s probably not the right fit if your child is brand-new to a topic and needs explanation. Num Drill assumes they know how multiplication works and just need fluency. For conceptual instruction, look at programs like Beast Academy or free-tier Khan Academy.

Privacy and data

Profiles, names, emojis, and per-player progress live in the browser’s local storage on your device. We never copy any of that to a remote server.

Quiz results — the questions, your child’s answers, timing — are sent to our server when they finish a quiz, so we can grade and store the score history. We log the requesting IP address and user-agent for abuse prevention. We do not collect names, emails, addresses, parent contact info, or anything that would identify your child as an individual outside of whatever display name your child types into the local profile pill.

We do not use third-party analytics, advertising trackers, or retargeting pixels. We do not have a Facebook pixel, a Google Analytics tag, or a TikTok pixel. The site is hosted behind Cloudflare for tunnel access; that’s the only third-party service the production site touches.

How to fit it into a week

The sweet spot for math fact practice is short and frequent: ~10 minutes a day, most days. A 10-question Num Drill quiz takes ~60–90 seconds for a fluent kid; doing three of them is enough. We expand on this on the methodology page and in our 10-minute routine post.

Multiple kids on one device

If you have a shared family iPad, each kid gets their own profile pill at the top of the home screen. Tapping the pill switches everything — weak-fact tracking, personal bests, mastery grid — instantly. No sign-in, no password. Profile data lives on that one device, so if your child uses Num Drill on a different tablet later, their stats won’t follow them across.

It’s free

Num Drill is free at launch and has no plan to introduce a paid tier. There is no premium upgrade, no pay-to-unlock-levels mechanic, and no subscription. If we ever change that, current features stay free.
