One worksheet.
Twenty-eight different copies. One print.
Compose a sheet from skill tiles, then choose what a single Print produces: a class set where no two children have the same questions, the same skills across four grade levels, or a week of spiral review. Answer keys are generated with the questions, so they can never disagree.
Three steps to a class set
The point isn't finding a worksheet. It's building the one you actually wanted, and then getting as many versions of it as the room needs.
Compose from tiles
Each tile is one narrow skill with its own settings. Click to add; stack as many as you want on one page. A sheet can cover exactly the three things you taught this week and nothing else.
Set the difficulty precisely
Not "hard" and "easy" — actual constraints. Force every subtraction to need a borrow. Cap the divisor at 9. Set marks per section and it totals the header.
Choose the run, then print
One dialog. A class set, a grade ladder, or five days of review — with keys for every version, and 4-up if the copier budget is tight.
What one Print can produce
You author the worksheet once. The run decides how many sheets come out and how they differ from each other.
One sheet
The worksheet as previewed. The default.
Up to 40 copies
Same skills and settings, different questions on every copy. Nothing to invigilate — there's nothing to copy from.
A grade ladder
The same tiles retuned for each grade across a range — Grade 2 through 5 in one print. Differentiation as one action.
Spiral review
One compact page taking a couple of questions from every skill, repeated for up to 30 days. Morning work and bell ringers, built.
A dated plan
The full sheet once per day for up to 30 weekdays, dated in advance. Hand out the stack; the practice runs without you.
Spiral review that pulls from what you've actually taught
Cumulative review is the format teachers buy most and the one that takes longest to assemble by hand, because it means going back through six weeks of topics and pulling two questions from each.
Tilo already knows which skills are on your sheet. Set questions-per-skill to two, ask for five days, and print. Every day has the same coverage and different numbers.
- Thins each skill down rather than dropping skills, so coverage stays complete.
- Compact layout — a full review fits the top half of a page.
- Keys for all five days come out of the same print.
The answer key is calculated, not typed
Every answer comes from the same calculation that produced the question, at the moment the sheet is generated. Nobody transcribes anything, so a key cannot contain a typo or drift out of sync with a page you edited.
That matters more with AI-generated worksheets in the mix: those write the questions and the answers in separate passes, which is exactly how you end up marking against a wrong key in front of the class.
- Answers only, or the full questions with answers filled in.
- Appended to the worksheet, or printed as its own file so it never lands on a desk.
- One key per copy in a class set, each labelled to match its sheet.
The accommodations your IEPs already ask for
Most support plans specify the same handful of things, and most worksheet generators can't produce any of them. These are switches, and they apply to every tile at once.
- Reduced questions per page — four or six instead of twenty, with the same total spread over more pages.
- Boxed digit columns — one box per digit so regrouping stays aligned.
- Enlarged text and spacing — up to 150%, with a wider, more even font.
- Nothing to copy out — questions are always printed, never transcribed.
Because the settings sit on the worksheet rather than the child, one authored sheet can be printed at standard size for the class and enlarged with four-per-page for the two pupils who need it — from the same build.
Designed to be cheap to print
Practice sheets are the first discretionary printing to get cut when a budget tightens. So the page is built to survive that conversation.
Built for the jobs that eat a Sunday
A class set where no two sheets match
Print 28 copies with different numbers on each, every one with its own labelled answer key. No seating-plan gymnastics for a Friday quiz.
Morning work for the whole week
Spiral review takes the skills you pick, gives each one two questions a day, and builds five days in a single print run.
Three ability groups from one build
Set a grade range and every tile retunes to it — the same skills, pitched three ways, instead of three separate worksheets and three separate keys.
A copy budget that got cut
Four sheets to a page, double-sided, is a supported layout rather than something you fight the printer dialog over.
Support plans that specify the format
Enlarged print, fewer items per page, extra working space. Build the sheet once and print it again with different accommodations.
An answer key that cannot be wrong
Questions and answers are computed from the same numbers at the same moment, so a key that disagrees with its worksheet is not a failure mode here.
Questions teachers ask
What does it cost?
Building and printing is free and unlimited, with no account and no trial. Every run mode, every accommodation setting and every answer key is included.
Do I have to upload a class list?
No — and there's nothing to upload it to. Everything runs in your browser. Type a class name if you want it on the header; it stays on your machine.
What about student data and privacy?
Tilo has no server, no account system and no analytics. It cannot collect student data because there is nowhere for data to go. Anything you type is used to render the page and saved only in your own browser. That usually makes the district conversation short.
Is it aligned to standards?
Not yet, and we'd rather say so plainly. Every tile carries an internal skill tag and the content is standard primary and lower-secondary material, but there is no Common Core or state-standard mapping in the interface today. It's on the roadmap and it's the main gap for formal adoption.
Can I get the same worksheet back next year?
Yes. Save it locally, or use Copy link — the link encodes the whole worksheet, including the random seed, so it rebuilds the identical questions on any device. Paste it into your planning doc and it still works next September.
How many questions can one sheet hold?
Up to 100 per tile on the four operations, which covers a traditional hundred-question minute drill. Most other tiles cap at 40. Sections that don't fit flow onto further pages, and word searches are kept whole rather than sliced across a break.
Does it work on a school network with no installs?
Yes. It's a single web page with no plugins, no extensions and no external requests, and it keeps working if the network drops mid-lesson.
Can I use it for sub plans?
That's one of the better uses. Print a week of dated sheets with answer keys as a separate file, leave the stack in the folder, and a supply teacher needs no briefing.
Build the sheet you actually wanted
Pick the skills you taught this week, choose a class set, and print. If it's useful, Copy link keeps it for next year.
