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. What Theorem can you use to find the third side length, given the other two lengths,of a right triangle? Add the letters of that word and go to the door of that room number.Pythagorean: room 11
2. What is the formula for the theorem? Go show the student assistant in the front office what you wrote down for your answer. (a^2)+(b^2)=(c^2)
3. What side of the triangle does "c" always represent in the theorem? Divide the number of letters by 5 and go to that floor. Take the stairs. hypotenuse: 2nd floor
4. The longest length of a triangle is a, b, or c in the formula? If a, go outside the bathrooms on the third floor. If b, go outside the bathrooms on the second floor. If c, go outside the bathroooms on the first floor. c: first floor bathrooms
5. Draw a triangle and label the sides a, b, and c. Go show the student assistant in Mr. Johnson's classroom. T.A. will have a pic of the possible correct answers: a, b are legs and c is hypotenuse.
6. Can you draw a right triangle where the side lengths are 15, 8, and 11? If yes, go to the wall of art ouside Ms. Tay's art class. If no, go to the announcements outside the front office. no: go to announcements outside the front office.
7. A right triangle has two legs with lengths 3 and 4. What must the length of the hypotenuse be? Add that number to 20 and go to the door of that room. 5:room 25
8. A right triangle has a leg with length 6 and a hypotenuse with length 12. What is the length of the other leg? Round to the nearest whole number. Go to the door of that room number. 10.39 round to 10: room 10.
9. A ladder rests on a wall. The ladder is 16 feet long and hits the wall 8 feet above the ground. How far from the wall is the bottom of the ladder? Draw a picture and solve. Round to the nearest whole number. Walk up that many stairs on the staircase by Mr. Holes room. 13.85 round to 14: 14 stairs.
10. Sabrina is building a slide for her son to play on. The stairs he will have to climb are 5 feet tall and she wants him to land on the ground 11 feet from where the stairs. How must the slide be? Draw a picture and solve. Round to the nearest whole number. add 26 to that number and go to that room. 12.08 rounds to 12. 12+26=38: room 38 (my room)
