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.

Question

Answer

1. Power: An expression that represents repeated multiplication of the same factorAn expression that represents repeated multiplication of the same factor.
2. Exponent: The number or variable that represents the number of times the base of a power is used as a factor.The number or variable that represents the number of times the base of a power is used as a factor.
3. Base: The number or expression that is used as a factor in a repeated multiplication.The number or expression that is used as a factor in a repeated multiplication.
4. Degree: The sum of the exponents of the variables in the monomial. The degree of a nonzero constant term is 0.The sum of the exponents of the variables in the monomial. The degree of a nonzero constant term is 0.
5. Monomial: A number, variable, or the product of a number and one or more variables with whole number exponents.A number, variable, or the product of a number and one or more variables with whole number exponents.
6. Polynomial: A monomial or a sum of monomials.A monomial or a sum of monomials.
7. Leading Coefficient: When a polynomial is written so that the exponents of a variable decrease from left to right, the coefficient of the first term is the leading coefficient.When a polynomial is written so that the exponents of a variable decrease from left to right, the coefficient of the first term is the leading coefficient.
8. Binomial: A polynomial with 2 terms.A polynomial with 2 terms.
9. Trinomial: A polynomial with 3 terms.A polynomial with 3 terms.
