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.
Question | Answer |
1. 1.The correct answer is choice (C) (–2, –4). Point P is located 2 units to the left of the origin, which gives us a value of –2 for x, and 4 units down, which gives us a value of –4 for y. Choice (A) is incorrect because the signs of the numbers are ignored . Choice (B) is incorrect because the coordinates are interchanged and the signs are ignored. Choice (D) is incorrect because it interchanges the coordinates. | 1 | 2. 2.The correct answer is choice (C) $0 .52. The cost per print is equal to the total cost divided by the number of prints: $13.00/25 = $0.52. Choice (A) is incorrect because it is the result of subtracting 0 .13 from 0 .25. Choice (B) is incorrect because it is the result of adding 0 .13 and 0 .25. Choice (D) is incorrect because it is the result of dividing 25 by 13. | 2 | 3. 3.The correct answer is choice (C) R (4, –2) and S (–2, –2). The given coordinates form a trapezoid. From –2 to 1 on the y-axis is a height of 3 units. While choices (A) and (B) do give coordinates that form trapezoids, the heights are not 3 units. In choice (A), the height is 2 units. In choice (B), the height is 4 units. Choice (D) is incorrect because the given coordinates do not form a trapezoid. | 3 | 4. 4.The correct answer is choice (B) 5(5 + 9). A common factor of 25 and 45 is 5. 25/5 = 5 and 45/5 = 9. So, 25 + 45 = 5(5 + 9). Choices (A) and (D) are incorrect because they only factor one of the two terms. Choice (C) is incorrect because it is the result of subtracting 5 from each term instead of dividing by 5 | 4 | 5. 5.The correct answer is choice (A) –1 > –4 because –1 is to the right of –4 on a horizontal number line oriented left to right. Numbers increase in value moving from left to right along the number line. Since –1 is to the right of –4 on the number line, –1 > –4. Choices (B), (C), and (D) are incorrect because the location of the numbers was confused, the sign of the numbers was not considered, and the relative positions of the numbers on the number line was misstated. | 5 |
