QR Challenge: maths exchange

Created using the ClassTools QR Treasure Hunt Generator

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

• Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
• Bring these devices into the lesson.

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!

Questions / Answers (teacher reference)

Question	Answer
1. 2D (2 dimensional) shape is any shape that can be laid flat on a piece of paper. Examples of 2D shapes include squares, triangles,square,oval, star, circles oblong,hexagon, rectangles, octagons, and even hearts	1
2. Perpendicular lines are lines that intersect to make a right angle	2
3. Parallel lines are 2 lines that do not intersect or meet at any point	3
4. Right angle is an angle that measures 90 degrees	4
5. Straight angle is an angle that is 180 degrees	5
6. reflex angle is an angle that is greater than 180 degrees	6
7. obtuse angle is greater than 90 degrees and less than 180 degrees	7
8. acute angle is an angle that is less than 90 dgrees	8
9. Polygon A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides	9
10. Quadrilateral is a 4 sided polygon	10
11. Triangle is a 3 sided polygon	11
