QR (Quick Response) codes, when read by a QR code scanner, can lead users to websites so that users do not have to type the URL manually.

With QR codes, a piece of paper can come alive with sounds, videos and/or more text. This caters to the different learning styles of students (ownership of learning). Students can also learn beyond what is given in the textbook or worksheet (extension of learning).
An example from a P3 STELLAR text:
Teacher includes all these QR codes that link to a map, a video and a dictionary on the cover page of the text.
Students can do this as a tuning-in activity in groups or individually (extension of learning). Alternatively, early finishers of work given can also do this as a filler activity while the other students can do this at home (learning at own pace - ownership of learning).
An example from a P2 STELLAR text:
Teacher includes an audio file for students to listen to as they read along. This is especially useful for students who have difficulty reading.
An example from a P1 Math topic:
Teacher lists down the learning objectives of that topic learnt and provides a QR code that link to a teaching video and some activities. This video can be viewed at home as revision.
