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

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.

Questions / Answers (teacher reference)

Question

Answer

1. The slide at the playground has a height of 6 feet. The base of the slide measured on the ground is 8 feet. What is the length of the sliding board? about 10.95
2. The bottom of a 13-foot straight ladder is set into the ground 5 feet away from a wall. When the top of the ladder is leaned against the wall, what is the distance above the ground it will reach? about 13.93
3. Amy’s television screen is in the shape of a rectangle. The height of the television screen is 24 inches and the width is 55 inches. What is the approximate diagonal measurement of the television screen? 60 inches
4. A 40-foot wire is attached to a pole and runs to the ground as shown below. The pole is 35 feet tall. 19 inches
5. Mr. Lopez has a rectangular classroom that measures 36 feet by 28 feet. What is the approximate diagonal measurement of the room? 46
6. A soccer field is 100 yards long and 60 yards wide. What is the approximate length from one corner of the field to the opposite corner of the field? 120
7. Bonus 1: In shop class, you make a table. The sides of the table measure 36" and 18". If the diagonal of the table measures 43", is the table “square”? (In construction, the term "square” just means the table has right angles at the corners.) it is not
8. Bonus 2: A baseball “diamond” is actually a square with sides of 90 feet. If a runner tries to steal second base, how far must the catcher, at home plate, throw to get the runner “out”? Given this information, explain why runners more often try to steal second base than third. 127.23
9. Bonus 3: Your family wants to purchase a new laptop with a 17” widescreen. Since the 17 inches represents the diagonal measurement of the screen (upper corner to lower corner), you want to find out the actual dimensions of the laptop. When you measured the laptop at the store, the height was 10 inches, but you don’t remember the width. Calculate and describe how you could figure out the width of the laptop to the nearest tenth inch. 13.75
