In this super secret number puzzle, students will practice working with finding approximations of the area between a curve and the x-axis. Students should be familiar with Riemann Sums (Left, Right, and Midpoint) and the Trapezoidal Rule.
Students find the answers to each of the six 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.
An answer key is included.
