In this puzzle students will practice solving problems about direct and inverse variation. In order to be successful with this activity, students need to be familiar with:
constants of proportionality
word problems that ask students to read and come up with an equation
Students find the answers to each of the ten questions and then add their answers together – this is the super secret number. After a bit of time, I tell them what the super secret number should be. If their super secret number matches mine, they probably did their problems correctly.
As an alternative, I have also included a page with a QR Code. This QR Code leads to the super secret number. To add excitement, students can scan the QR Code instead of just having the teacher tell the class the Super Secret Number.
