How to Use QR Codes in the Classroom: 5 Examples
If you’re a teacher interested in ways to successfully use QR codes in the classroom, here are five examples. They demonstrate how you can easily use the codes to do things such as add animations to worksheets, reveal worked answers and collect requests for help.
A QR code connects a printed page or classroom display to digital content. Students scan it using a classroom tablet or another permitted device to open the linked resource without typing a web address.
How to Create a QR Code
You can quickly create a QR code for the classroom using a QR generator tool. All you need is a link to the video, document, recording or form you want students to open.
- Copy a Link: Copy the sharing link for a video, document, audio recording or form. Check that students have permission to open it.
- Use a Generator: Paste the link into a QR generator and generate the code.
- Download and Label: Save the code as a PNG image, add it to your worksheet or display, and label what it opens, such as “Scan for the worked answer”.
Before the lesson, test the printed code using a classroom device. Scan it with the camera app or a browser-based QR scanner, and check that the linked resource opens correctly.
1. Add an Animation to a Water Cycle Worksheet
Create a QR code linking to a short water cycle animation and add it to a worksheet containing an unlabelled diagram. Ask students to scan the code using a classroom tablet, watch the animation, then label evaporation, condensation and precipitation on the worksheet.

General uses: QR codes can connect printed activities to videos, audio recordings and readings. Younger students could scan picture cards to hear animal sounds. Secondary students could scan a code beside a historical photograph to read an eyewitness account. Several codes on one worksheet could offer different reading levels or a choice of topics.
Benefits: Students move directly from the worksheet to the chosen animation without typing a web address or searching for the right video. Students working individually or in pairs can replay it while completing the diagram. Keeping the code on the worksheet also makes the animation easy to revisit during revision.
2. Reveal Worked Solutions at Maths Stations
Place a question such as 3/4 + 1/8 on a maths station task card. Add a QR code linking to a page showing the worked solution: 6/8 + 1/8 = 7/8. Ask students to attempt the question on paper, then scan the code to check their method and answer before moving to the next station.
General uses: Younger students could check addition using pictures of objects. Secondary students could follow worked algebra solutions. Beyond maths, codes could reveal corrected spellings, vocabulary definitions or explanations of science questions.
Benefits: Students receive feedback without waiting for the teacher to check each answer. A small code gives access to a full explanation without crowding the task card or placing the answer beside the question. Teachers can spend more time helping students who still need guidance after checking.
3. Play Student Recordings from a Classroom Display
Ask each student to record a 45-second explanation of their science poster. Save the recordings in a shared class folder, then place a QR code linking to each recording beside the matching poster. During a gallery walk, students scan the codes using classroom tablets and write one question for each presenter.
General uses: Younger students could describe their drawings or read a sentence aloud. Older students could explain a historical source, discuss an artwork or practise speaking in another language. Recordings could also accompany displays for a parent open evening.
Benefits: Visitors can hear students explain their own work without needing everyone to present at once. Each code connects a displayed project to the correct recording, adding detail without lengthy printed captions. Visitors can listen at their own pace and replay anything they missed.
4. Provide Video Help on a Homework Sheet
Record a short video showing how to solve a long-division problem, using different numbers from the homework questions. Upload it to the class learning platform and print a QR code linking to the video beside the first question. Students or parents can scan it at home to review the method before continuing.

General uses: Younger students could listen to letter sounds or hear homework instructions read aloud. Secondary students could watch a demonstration of balancing a chemical equation or hear the pronunciation of words for a language assignment. Codes could also link to homework submission forms or feedback explaining a common mistake.
Benefits: Families can see the method taught in class instead of searching for an explanation that uses a different approach. Help stays attached to the relevant homework sheet, and students can replay the demonstration whenever they get stuck.
5. Let Students Request Help from Their Desks
Create a short online form asking students to enter their name, question number and what they need help with. Print a QR code linking to the form on each desk. During independent work using classroom tablets, students scan it to request help while you monitor the responses and work through the queue.
General uses: Younger students could scan a code to hear task instructions or see the daily timetable. Older students could use codes to register attendance or book time with a teacher. A separate code could give relief teachers access to lesson plans and class routines.
Benefits: Students can ask for help without calling out or keeping a hand raised. Written requests show where they are stuck, helping you group similar questions or decide who needs attention first. A code on the desk opens the form without students searching through menus.

How QR Codes Support Classroom Learning
QR codes offer an efficient, clutter-free way to make learning more dynamic and engaging. They can be used strategically to connect students with explanations, feedback and extension activities when they need them.
For best results, remember to tell students when to scan and what to do next. For answer checks, ask them to attempt the question first. For videos, give them a question to answer or a diagram to complete so watching serves the lesson.
Don’t go crazy using QR codes however. They can become a distraction or waste of time when over-used. Short instructions are often better printed on the worksheet itself. Extra links and loosely related videos can also draw attention away from the activity.
