AP Precalculus Standard Addressed
This semi-log plot mystery picture activity is designed for AP Precalculus students working on topic 2.15 (Semi-Log Plots).
According to College Board’s Course and Exam Description, students are expected to “Construct the linearization of exponential data.” This is accomplished by graphing the exponential data on semi-log graph paper.
This activity specifically helps students practice graphing various points on semi-logarithmic graph paper.
Semi-Log Plot Activity Instructions
Once students have been taught to graph coordinates on a semi-log plot, they should be able to complete this activity with relatively no further instructions.
Students are given a set of 17 ordered pairs which must be graphed on the semi-log plot which is provided. Students graph each point and connect them in order with a straight line.
I suggest having students use a ruler or straight edge to make straight, crisp lines between each pair of points.
I also highly suggest having students mark off each ordered pair as they graph it to keep track of where they are in the mystery picture process.
Once students graph all of the points and connect them in order, a mystery picture will be revealed.
To give students further practice with understanding semi-log plots, students are challenged to add a face to their mystery creation. Once adding a face, they must list the coordinates of the points they connected to form the face.

Puzzle Solutions
Puzzle solutions are available on a password-protected solution page. I do not openly post the puzzle answer keys because one of my goals as a resource creator is to craft learning experiences for students that are non-google-able. I want teachers to be able to use these puzzles in their classrooms without the solutions being found easily on the Internet.
Please email me at sarah@mathequalslove.net for the password to the answer key database featuring all of my printable puzzles and math worksheets. I frequently have students emailing me for the answer key, so please specify in your email what school you teach at and what subjects you teach. If you do not provide these details, I will not be able to send you the password.
Not a teacher? Go ahead and send me an email as well. Just let me know what you are using the puzzles for. I am continually in awe of how many people are using these puzzles with scouting groups, with senior adults battling dementia, or as fun activities in their workplace. Just give me enough details so I know you are not a student looking for answers to the puzzle that was assigned as their homework!
