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. Given 16 matchsticks formed as directed (ask Ms. Ronco) move two matchsticks to make only four identical squares.
2. Construct 2 statistical graphs representing the cars in the lot in front of the media center. One graph for color, and one for type,(suv, sedan, etc).
3. If Ms. Ronco is teaching two AP statistics classes and ont he final exam, the 20 students in the first class averaged 92 while the 25 students in the second class averaged only 83, and the teacher decides to combine these two classes, what is the average of the final exam?
4. Using the following website: http://money.cnn.com/data/markets/nasdaq/ Find the information needed to construst a graph portraying the change in the market. Include any and all data used in an appropriate table.
5. Seven mature robins were caught and their wingspans were measured. The results, in centimeters, were: (23.1, 22.7, 22.1, 24.2, 23.9, 20.9, 25.2). Here are the corresponiding figures for seven mature house sparrows: (22.6, 24.1, 23.5, 21.8, 21.0, 24.4, 22.8). Find the mean and standard deviation of each species\' wingspan, and use these statistics to compare the two sets of figures.
