Students in Mrs. Matsko and Ms. Fincher’s sixth grade classes are finishing up their unit on expressions. To review, the students had to complete four “missions” that included finding the LCM & GCF of sets of numbers, finding the prime factorization of numbers, writing algebraic expressions, and simplifying algebraic expressions. As each mission was completed, the students received clues to find out “who stole Mr. Stone’s keys” and where the perpetrator “hid them.” The students had fun reviewing and finding out “whodunnit?”
