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.

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. (1) Find the diameter of a circle with a radius of 6.5cm | 13cm |

2. (2) Work out the circumference of a circle with a radius of 6.5cm using the formula C = 2r x pi (pi = 3.14) | 40.82cm |

3. (3) Find the area of 1 face of a cube that is 15cm long | 225cm3 |

4. (4) Find the volume of a cube that is 14cm long & draw it in your book | 2744cm3 |

5. (5) What does the "2" mean after a measurement of area? | Squared for a 2D object |

6. (6) What does the "3" mean after a measurement of volume? | Cubed for a 3D object |

7. (7) Find the volume of a rectangular prism that is 12cm long, 13cm wide and 15cm high | 2340cm3 |

8. (8) A local swimming pool needs a cover to keep it warm. If the diameter of the pool is 27 feet, what size cover is needed? Use the formula A = pi x r2 (pi = 3.14) and round to nearest whole number. Draw and label the pool using a suitable scale in your book | 572ft2 |
