A quick editing warm-up for the start of any lesson. Every school day brings a new fix it sentence with planted mistakes in punctuation, capitals, spelling, grammar and more. Students tap the words they think are wrong and type the fix, or you project it and reveal each correction with a short explanation.
How teachers use it
- Daily warm-up: project the sentence as students arrive. Read it, find it, fix it in books, then reveal one correction at a time and talk about why.
- Focus weeks: choose one mistake type, such as apostrophes or sentence boundaries, and the daily sentence comes only from sentences that practise it.
- Independent practice: share the class link so students open the right age band on their own devices, tap the mistakes and build a streak.
- Print a week: print Monday to Friday on one sheet with writing lines, plus an answer key page with every correction and explanation.
- Your own sentences: type a sentence with mistakes and the corrected version; the tool finds the differences, and you choose the mistake type and add a why.
Frequently asked questions
Is it free?
Yes. The fix it sentences, the projector view, printing and the class link are all free to use.
Do students need to sign up?
No. There are no accounts and no logins. Students open the page (or your class link) and start fixing.
Which ages is it for?
There are four age bands, 5–7, 8–10, 11–14 and 15–18, each with its own 200 school-day sentences and 20 Weekend Challenges. Younger bands focus on capitals, full stops and common words; older bands tackle comma splices, dangling modifiers, affect and effect, and who and whom.
Does it work on a projector or interactive whiteboard?
Yes. Teacher mode has a full-screen projector view with large, high-contrast text, a timer and four steps: Read it, Find it, Fix it and Reveal. Reveal the corrections one at a time or all at once, using the keyboard or a clicker.
Is student writing private?
Yes. Everything happens in the browser. Nothing students type is sent anywhere, and no names are collected. Streaks and settings are saved only on that device.
Does every class get the same sentence?
Yes. The sentence is chosen by date, so every class sees the same sentence on the same school day. At weekends there is a bonus Weekend Challenge, and you can catch up on missed days from the archive.
