1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.
2. If their phone camera doesn't automatically detect and decode QR codes, ask students to
4. Cut them out and place them around your class / school.
1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.
2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.
3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!
4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.
Question | Answer |
| 1. Charlie goes to the shops and decides to have a lucky dip from sweets tray. Inside are 3 Wonka bars, 4 Chilly Chocolate Creme, 2 Triple Dazzle Caramel, and 1 Nutty Crunch Surprise.

His choices are Mr Bucket, Mrs Bucket, Grandpa Joe, Grandma Georgina, Grandpa George or Grandma Josephine. If someone was randomly selected, what would the chance be of Mr Bucket being chosen? Write your answer as a fraction. | 1/6 | 3. Charlie and Grandpa Joe have made it to the Chocolate Factory! At the gates, a reporter tells them that Veruca's father had opened exactly 3 million chocolate bars before finding the golden ticket. Since Charlie opened only 3, how many times more likely was Veruca to find ticket than Charlie? You can use a calculator for this question. | 100000 | 4. Veruca and Violet are arguing again! This time over the Oompa Loompas. Veruca decides that they should flip a coin three times to see who takes one home with them. Violet wins the game is three heads are flipped in a row. What is the probability of that happening? Use a tree diagram to work this out. Give your answer as a fraction. | 1/8 | 5. Mr Wonka shows the children the bubblegum making machine. They can choose between red, blue or yellow gum and then decided if they want a 1, 2 or 3-course tasting meal. How many different possible options are there?

He eats a red one. He then goes back for seconds. If he chooses an apple randomly, what is the chance of it being green? Write as a decimal. | 0.3 | 7. In the Nutting Room, Veruca decides she wants a squirrel to add to her 20+ pets at home. There are 100 trained squirrels in the room. If half are brown squirrels, 20 are red squirrels and the rest are a mixture of red AND brown squirrels. Veruca closes her eyes and randomly grabs one. What is the chance of it being a red AND brown squirrel? Write as a percentage. | 30 | 8. Mike TeaVee wants to be teleported. There are 10 flashing buttons in front of him. If 4/10 of the buttons are red and all the rest are green, what is the probability of him randomly pressing a green button? Write your answer as a decimal. | 0.6 | 9. Charlie enters the great glass lift. There were buttons everywhere! There must have been a thousand of them on each of the four walls, and another thousand on the ceiling! Charlie is allowed to randomly select a button. What is the chance that the button he selects would take him to the Fizzing Lifting Drinks room? Write your answer as a fraction. | 1/5000 | 10. Mr Wonka decides to give the factory to Charlie. He had planned to give it to one of the children all along. At the start of the day, what had the chance been that Charlie would win? Write your answer as a fraction. | 1/5 |
