for parents and teachers · always free

Short, daily practice, marked as they go.

Free maths and word practice for children aged 4 to 15. Pick a school year and Pencilhop sets a short drill that marks every answer with a red ○ and times it to a tenth of a second. Times tables, 100-cell grids, worksheets, spelling and more, in four languages.

Which school year?

From Year 5 the page turns calmer: older children drop tools that look young.

Today's set · Year 22-digit addition

  1. 24 + 13 = 37
  2. 45 + 28 = 73
  3. 29 + 19 = 48
  4. 52 + 36 = 88

Tap a line and answer with the number pad. Right answers get a red tick, or a ○ the way teachers in Japan and Korea mark.

A Sunday report, sent where you already chat

Pencilhop turns the week's practice log on this device into a short summary for family on WhatsApp, LINE or KakaoTalk: days practised, minutes and accuracy. No account needed.

A class set in two clicks

Print one sheet for every pupil, or A and B versions so neighbours can't copy, each with its own answer key. Keep the sheet number and you can print the exact same sheet next year.

How Pencilhop works

  1. Pick a tool and a level

    Choose a school year or a tool, then set the numbers, how many problems and the time. Every setting lives in the link, so a bookmark brings back the same drill.

  2. Hand over the device

    Tap Start on this device. The screen shows one problem or one grid, a number pad and a timer: no chat, no ads, no links out. Hold the corner button to exit.

  3. Marked as they answer

    Each answer is checked the moment it's typed, with a red ○ or ✓. The page works every answer out itself, so the marking is always right.

  4. Print it, or plan with ChatGPT

    Every tool prints on A4, JIS B5 or Letter, with the answer key on its own page. Ask ChatGPT what your child should practise next, then open the matching Pencilhop link.

Questions parents ask

Is Pencilhop really free?

Yes. Every practice tool is free, with no account and no ads, and it stays that way. Pencilhop Plus, coming later, will add optional extras that need an account, such as weekly reports and profiles for several children. You can pre-register here.

Do I need to sign up?

No. Open a tool and start. Personal bests and practice logs are kept in this browser, and Clear this device at the bottom of every page removes them. See the privacy page.

Which ages and school years is it for?

Roughly 4 to 15, from preschool to lower Secondary. Pick a school year at the top; from Year 5 the page switches to a calmer look that older children won't find babyish.

Does it work on a tablet or phone?

Yes. Pencilhop runs in the browser on an iPad, Android tablet, phone or computer, with nothing to install. You can add it to your home screen, and pages you've opened before also work offline.

Can I print the sheets?

Yes. Every tool prints on A4, JIS B5 or Letter, with the answer key on its own page and a QR code that opens the answers on your phone.

Can teachers use it with a whole class?

Yes. The worksheet maker prints class sets with A and B versions and an answer key, and the sheet number brings back the same sheet any time. Flash mental maths has a projector mode with huge digits.

Is Pencilhop linked to Eiken, Kanken, PSLE or CAP?

No. Pencilhop isn't connected to any exam board. The exam pages give the official dates and facts, checked on each organiser's site, and point to tools that practise the same skills.

Why ○ instead of ✓?

In Japan and Korea a circle means correct and a tick can mean wrong. Each language uses its local mark by default, and you can switch it on any tool.
