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. Distance the number is from zero on a number lineAbsolute Value
2. 2 expressions that equal each other; separated by an =Equation
3. small number raised above a number or variable; means how many times that quantity is multiplied by itselfExponent
4. terms that have the same variables with the same exponentsLike Terms
5. All positive and negative whole numbersInteger
6. the horizontal axis on a graphX-axis
7. the vertical axis on a graphY-axis
8. a symbol(usually a letter) that represents an unknown quantityVariable
9. a number that remains the same even when the values of the independent and dependent variables change (y-intercept in slope-intercept formConstant
10. y = mx + b; form that an equation must be in to use y= on the calculator; m is the slope and b is the y-interceptSlope Intercept Form
11. terms that do not have the same variables with the same exponentsUnlike Terms
12. The answer to an addition problemSum
13. The answer to a subtraction problemDifference
14. The answer to a multiplication problemProduct
15. The answer to a division problemQuotient
16. The rate of change in an equation; rise/run; change in y/ change in x; the angle that the graph of a line slantsSlope
17. Where the graph crosses the y-axis; the constant in a linear equation; b in an equation written in slope-intercept form; where x= 0 in the table of an equationy-intercept
18. where the graph crosses the x-axis; where y= 0 in the table of an equationx-intercept
19. lines that intersect at a 90 degree (right) anglePerpendicular
20. numbers and variables combined with arithmetic operationsExpression
21. To solve and find an answerEvaluate
22. Makes a line; parent is y = xLinear
23. Makes a parabola; parent isy = x²; has an x² as the highest exponent in the equationQuadratic
24. x’s don’t repeat, each independent value is paired with exactly one dependent value; graph passes the vertical line testFunction
25. All x(independent) values in a set of dataDomain
26. All y(dependent) values in a set of dataRange
27. The variable that is used to calculate the answer; the x value; the value that cause the answer to changeIndependent
28. The answer that is being calculated; the quantity that depends on the other quantity; the y valueDependent
29. To make an expression easier to understand/shorter; simplified expressions ARE equal to the originalSimplify
30. Where a Quadratic Equation crosses the x axisRoots
31. where the equation crosses the x axisZeros
32. the bending point of a quadratic equationVertex
33. The way the values in a set of data are related; can be positive, negative, or no correlationCorrelation
34. Lines that never intersect; lines that have the same slope but different y- interceptsParallel
