Metric Murder Mystery: Teaching Math and Information Literacy in a Middle School Media Center

Needs Assessment For the last several years, 6th grade students scored poorly on metrics and measurement section of CRCT Teachers confirm that students struggle in this area Strategies rarely include performance-based but focus on teacher led, direct instruction

Methodology Metric Murder Mystery: math, media literacy, critical thinking, collaboration with peers, writing Used the steps of the Big 6 to solve a murder mystery and to answer math problems; also used Cobb Virtual Library databases Incorporated word problems, conversions, and measuring (areas of weakness identified by assessment and teacher observation)

PE Teacher, Mr. Kevin Goss, killed at Palmer Body found in media center As CSIs, students must solve murder

Placed in CSI Teams and taught Big 6 Given crime scene photos, current evidence, and suspects: four Palmer teachers in a notebook

Four labs: Murder Weapons, Water Bottle, Murder Scene, and Shoebox Must apply Big 6 steps to each lab in order to solve the murder

Lab #1: Murder Weapons Weapon must weigh 48 oz. to have caused deadly blow Weighed in pounds Converted Had to choose most logical measurement Explain choices and conclusions

Lab #2: Water Bottle Leaked from murder scene to media center at rate of 3.7mL per meter Find volume Convert mL to Liters Conclude murder scene

Lab #3: Murder Scene Blood found in three places Measure distance from body to three places Covert meters to kilometers Choose most logical

Lab #4: Shoebox Surface area of shoebox found Area of blue fiber items used to cover box and clean murder scene Convert feet to inches Draw conclusions

Murderer Identified! Used CSI Notebook Considered all evidence Wrote paragraph naming murderer and evidence to support

Instrumentation Pre and Post-Test Teacher and Media Specialist Observation Student Comments

Results (cont.) Question #6: No student work included Question #10: Interpreted the problem as one of area instead of perimeter Question #11: Majority of answers missed were the half and sixteenth measurements Questions #12: Struggle with which direction to move the decimal

Question #13: Big 6 “You can use the Big 6 in a math problem by identifying the problems, seeing what sources you can use to solve it, finding the information from the sources, using the information and evaluating the answer and then solving the problem.” “You can use the Big 6 to solve a math problem. You just follow the six steps. It works because one step tells you to read the problem and another tells you to make sure your answer is reasonable. So if you follow the steps you will have read, answered, and checked the problem.”

Observations “Awww, I don’t want to go yet!” “Well, I didn’t know what I wanted to be until just now with this lesson, but I want to be a CSI.” “This is so much fun!” and “That’s so cool!” Comments across the room could be heard, like “I remember in class yesterday and Mrs. Waters was saying…,” and “No, remember, the decimal goes this way…,” and “Let me show you. I took this….”

Teacher Comments “Wow! This was great!” Never seen their students so engaged in solving math problems and so intent on making accurate deductions One teacher mentioned wanting to do similar activities for other math units Another mentioned using the steps of the Big 6 in her class in an effort to help the students solve all math problems

Modified Action Plan Shortened amount of time between unit and mystery Additional labs to speed completion Include problems that address perimeter, 1/16” measurements, more conversions Time in media center for post-test More performance assessments needed overall

Overall, Metric Murder Mystery will return for a second season next year! PALMER
