QR Challenge: Algrebraic Expressions and Inequalities

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

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. Solve the equation using the solution set: (3,4,5,-3,-5): 4x-3=175
2. From the set (7, 12, 15), which value can be substituted for c to make the equation true? 90-2c=6015
3. From the set (5, 13, 23), which of the values can be substituted for me to make the equation true? 6+m=1913
4. What is the value for n that makes the equation true? n+7=2114
5. What is the value for t that makes the equation true? 4t=4812
6. Kellie bought 9 towels and spent $36.54. Each towel costs the same amount. Write an equation to solve this: 9t=36.54
7. Solve the equation: 8t=39.60
8. Cirrus clouds form more than 9,000 meters above Earth. Write an inequality to represent h, the height, of the cirrus clouds.h>9,000
9. Translate the following sentence into an inequality: It's colder than -14 degrees F outside right now. t<-14
10. Describe how I would graph m <0 on a number line. (I.e. open/closed circle, arror pointing to the left or right?)open circle, arrow to the left.
