Why there's no answer key
These are for practice. Every question carries a short Clarify line that points at how to think about it — and stops there.
None of them print an answer key. Not because the answers are secret — nearly all of this you could look up online in a minute if you wanted to.
It's because a mentor who reads the question, works the reasoning out, and talks it through with the student builds something a letter in a table never will: the student comes away understanding why, and the two of them got there together. Each sheet has a mentor guide at the back for exactly that.
Before you use one
These were written for one specific group of students, so treat them as a strong first draft rather than a finished worksheet — open the file, change the wording, cut what doesn't fit the person in front of you.
- Take the HTML if you want to change the wording — it opens in any browser and edits in any text editor. Take the PDF if you just want to print it.
- Downloaded files keep working with no internet at all.
- The mentor guide is written for the adult. Print the student pages separately.
- No analytics, no accounts, no tracking of the student. Nothing anyone types is transmitted or saved — it stays in the browser and disappears when the tab closes.
- Everything here is MIT licensed — use it, change it, put it in your own program's name. No credit needed.
- No support and no update schedule. If something is broken or reads badly, tell me and I'll fix it.
Nothing matches that search.
Using one of these?
I'd genuinely like to know — especially if something is wrong, out of date, or reads badly for the student in front of you. That's the only feedback loop these have.
arvi@tervik.orgThese came out of running a program day to day — the scheduling, the attendance, the paperwork that eats an afternoon. That side of it is what I build software for. If something in your week works that way, tell me about it.
