QR Codes in the Classroom: Ideas for Teachers

Simple ways teachers use QR codes: quizzes, treasure hunts, reading extras and quick links to resources.

QR codes turn a printed page into a doorway. Teachers use them in many small, practical ways.

Quick links

Put a plain-text QR code with the answer on the back of a card. Students scan to check.
Make flashcards where the code reveals the meaning of a word.

Hide codes around the classroom or school. Each one gives a clue for the next. Plain-text codes work offline, so no internet is needed.

Vocabulary labels on classroom objects, with the code holding the word in another language
Pronunciation links to audio recordings
Short quizzes at the end of a lesson

Print the code large enough for a group to scan.
Add a label so students know what each code does.
Test every code before the lesson.
Have a backup for students without phones, such as a printed link or a shared device.
Check pages for suitability before sharing with children.

Teach students to preview a link before opening it, and to scan only codes that come from a trusted source.

QR Code Scanner's built-in generator makes text and link codes, so you can build activities and test them on the same phone.
