QR Challenge: Triangles
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.
Questions / Answers (teacher reference)
Question | Answer |
| 1. Yesterday we learned the names of angles and how to classify (name) the angles. Today you will be looking at triangles. As you learn about triangles, see if you can connect your learning from yesterday to today. On QR Codes A-F, draw the triangle. If you need help on what the triangle looks like...ask your friend "GOOGLE". | R
|
2. Draw a right triangle. | a
| 3. Draw an obtuse triangle. | b
| 4. Draw an acute triangle. | c
| 5. Draw a scalene triangle. | d
| 6. Draw an isosceles triangle. | e
| 7. Draw an equilateral triangle. | f
| 8. On QR Codes 1-6, put the information that describes the triangle under the correct flap. | S
| 9. A right triangle has one right angle. | 1
| 10. An obtuse triangle has one angle that is greater than 90 degrees. | 2
| 11. An acute triangle's angles are all less than 90 degrees. | 3
| 12. A scalene triangle has no equal sides. | 4
| 13. An isosceles triangle has two equal sides. | 5
| 14. An equilateral triangle has all equal sides. | 6
| 15. Was what you learned yesterday helpful? Why? | 7
| 16. Get a pipe cleaner from the front table. Bend it to create a triangle. Take a picture of the trianlge and label the triangle. Continue doing this until you have a picture of all 6 types of triangles. | 8
| 17. Bend your pipe cleaner into the triangle of your choice and create a poster to display. The poster should have your triangle, put the name of the triangle, and what makes it that type of triangle. Place your name on the back and put it under a clothes pin. | 9 |
