Fourteen kinds of question, all of which fit a single grid cell:
8 + 7 = ▢ |
addition, subtraction, multiplication, division |
5 + ▢ = 9 |
missing number |
5 ▢ 3 = 8 |
missing sign - always exactly one correct answer |
5 ▢ 8 |
compare two numbers, or two calculations |
2, 4, 6, ▢ |
number sequences, with the blank at the end or anywhere |
5 + 3 = 4 + ▢ |
balancing equations |
47 = 40 + ▢ |
splitting a number |
½ × 18 = ▢ |
a fraction of a number |
Set separate ranges for the numbers in the question and for the answers, so real times tables work: numbers to 12, answers to 144. Put a lower bound below zero and you get negatives. Lock the answer to 10 and missing-number questions become number bonds.
Every sheet carries a hint matched to the exercises on it - a method, not encouragement. "17 - 14 is the same as 7 - 4. The tens cancel each other out." There are 35, in English, French and Dutch.
Every sheet is rated one to six stars, computed from the questions themselves rather than from which boxes you ticked. Three things it deliberately does:
- Big numbers cannot buy stars. Twenty additions with numbers up to 1000 rates two or three. Grinding is not rewarded.
- One format repeated cannot reach the top. Twenty balancing equations, the hardest single idea here, tops out at five and a half.
- Breadth is the route to six. It takes four or more different kinds of exercise on one page, and usually negatives too. Changing method between questions is genuine work: they have to recognise what they are looking at before they can start.
The point is that the rating has to be honest. A child who gets used to scoring highly on something easy will not enjoy the day it stops being easy.
Set a lowest star level, a highest, and how many sheets. It works out which
combinations of exercises hit each level, generates them, and gives you a ZIP of
PNGs named by level - star-3.5-04.png. A week of homework in one click.
It only uses exercise types you have switched on. If they are not doing division this week, no sheet in the batch contains any.
Download mathsheets_public_v1.html and open it. That is the whole setup.
Save Image gives you a PNG at A4. Print it at 100% with no scaling - PNG rather than PDF because PDF printing kept producing margin and border errors.
Settings, layout and everything else are remembered in your browser between sessions. Nothing is sent anywhere; there is no server to send it to.
Works on a laptop, and on a phone or tablet, where the controls collapse to a strip of coloured tabs down the right edge and slide out over the sheet when you tap one.
Because everything is in it, on purpose.
| Part | Size | Why |
|---|---|---|
| Fonts, 8 Latin subsets | 213 KB | Loaded from a CDN, the interface silently falls back to whatever the machine has, and two of the five sheet fonts stop working entirely |
| html2canvas | 199 KB | Save Image and the batch depend on it. From a CDN it fails silently offline |
| 10 illustrations | 241 KB | WebP, for the corner of the sheet |
| The generator | 128 KB | Questions, difficulty model, 35 hints in three languages, interface, batch |
The trade is a 780 KB file that works anywhere and will still work in ten years, against a 128 KB file that needs three folders and a working network to be what it looks like. For something meant to be downloaded and kept, the first is worth more.
There is no build step, no bundler, no dependencies to install and nothing to keep up to date.
It is one file, so open it in any editor.
- Hints are in
HINTS_BUILTIN. Each has anopslist saying which exercise types it applies to, and text in three languages. - Difficulty weights are in
DIFF_BASE, one number per exercise type, with the reasoning in comments. - Corner illustrations are base64 WebP in
CORNER_GRAPHICS. - Interface text is in
i18n, three languages.
