QR Challenge: Analysis
Teacher Notes
A. Prior to the lesson:
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
- Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
- Bring these devices into the lesson.
3. Print out the QR codes.
4. Cut them out and place them around your class / school.
B. The lesson:
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!
C. TIPS / OTHER IDEAS
4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.

2. Haunted house Ahhh and BOO! are 450km apart, on an east-west line. Richard is so scared and confused that he runs in a northeast direction from Haunted House Ahhh to Haunted House Creepy to grab Tianshuo. From HH Creepy he and Tianshuo run 359km on a bearing of 128° 40’ to Haunted House BOO! where they meet up with Purushottam. How far is Haunted House Creepy from Haunted House Ahhh? | 1

| | 4. A spooky hill slopes at an angle of 12.47° with the horizontal. From the base of the hill, the angle of elevation of a 459.0ft Tower of Terror at the top of the hill is 35.98°. Purushottam is too scared of the tower and he needs an escape route. How much rope will he need to reach from the top of the Tower of Terror to the bottom of the spooky hill? | 1
| 5.
| | 6. Tianshuo saw a ghost and started running due north. At a certain point the bearing of the ghost 12.5km away is N 38.8° E. Obviously Tianshuo keeps running. He then notices that the bearing of the ghost has become S 44.2° E. How far did Tianshuo run between the two ghost sightings. | 1
| 7.
| | 8. Richard wants to catch tricker treaters. He hangs a heavy basket of candy that is supported by cables attached to both ends of a camouflage beam, as shown in the figure. What angles are formed between the beam and the candy baskey?? | 1
| 9.
| | 10. Tianshuo and Purushottam are hiding from zombies at points A and B, respectively, which are 3.46mi apart on an east-west line, with A west of B. From Purushottam’s point of view, the bearing of a certain zombie is 47.7°, and from Tianshuo’s point of view the bearing of the zombie is 302.5°. The zombie picked up Purushottam’s scent at point A. Find the distance between Purushottam and the Zombie. | 1
| 11.
| | 12. Richard loves pumpkins and wants to make a triangular lot to put pumpkins in. A surveyor takes measurements and finds that two sides are 52.1m and 21.3m, and the angle between them is 42.2°. What is the area of the pumpkin triangular lot? | 1
| 13.
| | 14. Tianshuo loves math so much that he wants to be a triangle for Halloween. He wants to paint the cardboard triangle, so he measure the sides of the triangular costume to be 52in, 63in and 75in. How many square inches of paint will he need to paint the costume? |
| 15.
| | 16. What is the measure rounded to the nearest tenth degree of one of the larger angles of a parallelogram in the xy-plane that has vertices with coordinates (2, 1), (5, 1), (3, 5) and (6, 5)? | 1 |
