## 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

• Bring these devices into the lesson.

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 The 3 ways to classify a triangle by its sides are? Scalene, Isosceles and Equilateral What is a polygon? A figure with more than 3 sides and NO curved sides How many degrees do the angles in the triangle add up to? 180 degrees How many degrees do the angles in the quadrilateral add up to? 360 degrees Which shape has 2 pair of parallel sides, opposite sides congruent and also right angles? Rectangle Which 2 Quadrilaterals have all congruent sides? Rhombus and Square I am a triangle with side lengths of 5, 7, 10 and angle lengths of 30, 50 and 100. Who Am I?? Scalene Obtuse Triangle I am a triangle with angles of 50 and 40. What is my missing angle? 90 degrees I am a triangle with sides of 10, 6, 10. The angles are 40 and 40. What is my missing angle and who am I? 100 degrees and I am an Isosceles Obtuse Triangle A square is _________________ (always, sometimes or never) a quadrilateral. Always Which of the following are NOT quadrilaterals: octagon, parallelograms, triangle and trapezoid? Octagon and Triangle There are 3 angles in a quadrilateral: 60, 60 and 120. What is the missing angle? 120 degrees Which has ONLY one pair of parallel sides? Trapezoid A triangle has angles of 15 and 15 degrees. What is it's missing angle? How would you classify it by the angles? 150 degrees and it is an Obtuse Triangle What is a closed figure? a shape where all the sides connect What is a Regular figure? What could you do to make a shape irregular? A regular figure is where ALL sides are congruent. To make a shape irregular you need to change some of the sides so that they are not equal. What am I? I am a 4 sided figure with 2 pair of congruent AND parallel sides. Parallelogram What is the missing side in the quadrilateral below. Three of the sides are 85 degrees, 95 degrees, 100 degrees. What is missing? 80 degrees What side is missing in the triangle? This given sides are 36, 84 and ?? 60 degrees ### Quadrilaterals and Triangles Review: QR Challenge Question 1 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 2 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 3 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 4 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 5 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 6 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 7 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 8 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 9 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 10 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 11 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 12 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 13 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 14 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 15 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 16 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 17 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 18 (of 19) ### Quadrilaterals and Triangles Review: QR Challenge Question 19 (of 19)
