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.

17. On Thursday there were six times as many flowers as on Wednesday. On Friday another twelve flowers appeared. There were 36 flowers altogether. How many flowers were in the garden on Friday?6x + 12 = 36
18. Write an equation to represent the following problem (you can solve for the variable for a challenge): Martha had some questiosn for Maths homework. In history she got DOUBLE the number of questions she was given in maths. Then she went to English and was given 4 more questions. At the end of the day, Martha had 28 questions to do. How many maths questions was Martha given for homework3x+4=28
