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
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.

If there are 196 legs and 126 eyes at the dog show, how many people and how many dogs are present?

Then she picks up her pace and runs the last half of the race at 6 miles per hour. What is her average speed on the course? | The answer is not 4.5 miles per hour. Assume the course is 24 miles long. Louise needs 4 hours to run the first 12 miles (the first half of the course) and 2 hours to run the last 12 miles (the last half), meaning she needs 6 hours to run the total of 24 miles. Therefore, her average speed is 4 miles per hour. | 9. Marina, her sister, her daughter, and her son are playing volley ball on the beach. Marina's sister is directly across the net from her son. Marina's daughter is diagonally across the net from the best player's sibling. The best player and the worst player are on the same side of the net. Who is the worst player? | Marina’s sister | 10. Three clocks in the train station give the following readings: CLOCK A: 8:00 CLOCK B: 8:50 CLOCK C: 8:20. One clock is 20 minutes fast. One clock is slow. One clock is off by half an hour. Help the passengers figure out what time it really is. | 8:30 | 11. Jack and Jill were practicing batting. Jack's first time at bat, he hit 75 out of a hundred pitches thrown by Jill. Then Jill hit 75 out of a hundred pitches thrown by Jack. After a little break, Jack took a second turn at bat. Jill threw him 50 pitches, and he hit 35 of them.
