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. Dr. Russell had 22 first grade students and 18 kindergarten students going on a field trip. She could only fit 10 students per bus. She used this number sentence to figure out if she could 22/10=2.2. Is Dr. Russel guilty of using the wrong number sentence or innocent because she used the right number sentence. Explain you answer. | Guilty. She should have added the number of students to find the total number of students getting on the bus.

He had to put the rest in to CD cases so that each case had the same amount. He knew each case could only hold 5 CD's. He used the number sentence 50 + 15 = 65, 65/5=15 to determine that he needed 15 cases. Is Derrick guilty or innocent. Explain your answer. | Derrick is guilty because he should have subtracted 15 CD's from his total number of 50 instead of adding. Then, he could divide by 5. He would need 7 cases. | 3. Shaunterrin planted a garden. She had 3 rows of strawberries. Each row had 4 strawberry seeds in it. When they were all ripe, she ate 5 of them.
