About CodeAcorn
CodeAcorn is where school students learn to build web pages with HTML and CSS — in class with their teacher, and on their own afterwards.
Why it exists
Learning to code in a classroom is hard to get right. Some students race ahead, others get stuck on a missing > and give up,
and teachers spend the lesson walking between desks. CodeAcorn was made by a teacher to fix that: everyone follows the same live lesson,
then works at their own pace with a checker that explains every mistake in plain words.
How lessons are built
Each week is one small idea — a tag, a selector, a property — taught in a few steps:
- Live lesson. Slides with examples, “predict what the browser will show” questions and common mistakes side by side.
- Try it. Practice with instant checks. No marks — just proof that it works.
- Assignment. The marked task. Students hand it in and see their score and tips straight away.
- Challenge. A bonus for anyone who wants more: find and fix the bug.
For teachers
Teachers run live lessons from any laptop or projector, see who is following, open weeks for each class, and review every hand-in from one inbox. Scores are calculated automatically and can be changed, comments reach students by email, and term grades export to a spreadsheet.
Who can sign in
Accounts are created by the school, so there is no public sign-up. Students sign in with their school Google account. The course outlines are open for anyone to read on the Courses page.
