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. What is a hidden question? | a question that you must solve for but is not specifically written down | 2. What is a partial difference? | finding the difference by taking pieces of the subtrahend | 3. Write the steps to solve 284-123 | 284-100=184. 184-20=164. 164-3=161 | 4. Find the difference of 534-108 using partial differences | 426 | 5. KeShaun wants to find the difference for 716-294 using partial sums? What is his first step? (What does he subtract first?) | 716-200 | 6. Makai is answering 826-179 using partial sums on his test. He did 826-100=726. 726-79=646. Where does he go wrong? Should he have taken another step to make it easier on himself? | should've subtracted 726-26. 79-26=53. 700-53=747 |
