Do you like mysteries? Do you like math, or need some support for pre-algrebra skills, such as those learned in 7th and 8th grade?  Join me as we learn pre-algebra skills and complete math mysteries. Join Collin, Owen, and Lilac, who run the school newspaper, as they search for stories to write and solve mysteries they find. This class will reinforce pre-algebra concepts, give students more practice, and encourage learners, all while focusing on solving a mystery.  Students who are math whizzes and students who need review are all welcome! Class sizes are limited to 5 students. Class ranges from 35-40 minutes.

Each class will begin with a question of the week and math related joke of the week, then we will read the case that we are working on. Cases may involve eliminating suspects or finding missing animals or people. Then I will present and model the math skill of the week. Students will work together to complete a few examples of the skill. Students are then given time to work independently or as a group to complete the math problems, which will spell out the clue for the day. Class ends with everyone sharing the clue and eliminating the suspect or marking on a map the next location for the missing animal. Most classes have 16 math practice problems to complete during independent work time. Most mysteries last 4 weeks, but students can join the class at any time. Students who join mid-mystery will be given clues that have already been discovered. At the end of the mystery, students are given a certificate for solving the case!
