ChalkBee: Printable Worksheets With Maths Answers That Are Never Wrong
Every parent and teacher hits the same wall eventually: a kid needs more practice on, say, adding fractions or telling the time, and you go looking for a worksheet. What you find is a mess. Half the sites bury one worksheet under a pile of ads, the good ones want a subscription before you can print anything, and a worrying number of the newer ones use an AI to make up both the questions and the answers, which means the answer key is sometimes just wrong.
That last part is the one that bothered me most. A worksheet is worthless if you cannot trust the answers, and a child being marked wrong for a right answer is worse than no worksheet at all.
So I built ChalkBee, a library of printable worksheets for primary school across maths, reading, science, geography, history and more. You pick a subject, a topic and a grade, and you get a clean worksheet you can print or use on screen, with a matching answer key.
The maths answers are computed, not generated
This is the part I care about most. On ChalkBee, the maths is never handed to a language model. Every maths question is generated by code, and its answer is worked out by the same code that made the question. If a sheet asks for 47 + 68, the key says 115 because the program added it, not because a model guessed. That makes the maths answer keys correct by construction, every time, which is exactly the guarantee a teacher or parent needs.
Organised the way you actually look for it
The worksheets are sorted by topic (number bonds, skip counting, place value, comparing numbers, patterns, and more) and by grade, so you can go straight to the thing a child is working on rather than scrolling through a giant undifferentiated list. Each topic usually comes in a few alternate sets at the same difficulty, so when a kid finishes one you can hand them a fresh set of questions on the same skill without repeating the exact same sheet.
Generous freemium, built to stay clean
ChalkBee runs on a generous freemium model: I want to give away as much as possible while keeping a viable business behind it, funded by the teachers who lean on it every week. There is a lot you can print for free, and premium options add the extras teachers ask for. It runs on the edge so it loads fast anywhere, and it is deliberately plain: the page is the worksheets, not a wall of banners. The goal is that a busy parent five minutes before dinner, or a teacher the night before class, can find the right sheet, print it, and move on.
