  3. Introduction You will be participating in an excerpt from the a Math Day Murder Mystery put on by the Hawaiʻi Noyce Teacher Scholarship recipients at the Big Island Math Summit. Lesson plans for these activities can be found on the HiNTS website. http://www2.hawaii.edu/~hints/hints.html

  4. About the Big Island Math Summit • The Big Island Math Summit was • a one-day event, • scenario-based, and • an active learning professional development opportunity for Big Island teachers.

  5. WE’VE GOT A MURDER ON OUR HANDS!!! • A Mathematics Professor has recently been murdered. • Prime suspects include 5 HiNTS Scholars. • Through a series of activities, based upon 5 Texas Instrument activities, clues will be uncovered that will aid in the capture the murderer. • While 5 activities were conducted at the Math Summit, we will only be doing the first two here due to time frame constraints.

  6. Tracks of a Killer • Upon leaving the scene of the crime, the murderer left a trail of footprints. • You are to determine whether or not there exists a relationship between stride length or shoe size and height.

  7. Hit and Run • A stop sign was hit on the night of the murder and each HiNTS scholar has evidence of bumper damage. • You will attempt to recreate a hit and run and compare it to vehicle data retrieved from the scholars’ cars.

  8. Dropped at The Scene • The victim managed to put up a fight leaving the murderer with a bloody nose where drops were discovered at the scene. • CSI’s evaluated the blood spatter from the crime scene to predict the height of the murderer was between 5’ 7” and 6’1”.

  9. Suspect Radius • Suspects claimed they were all occupied the day of the murder which occurred in UCB 314. • The scholars got out of class in UCB 314 at 3:00 pm. • College Hall is on the other side of campus from UCB.

  10. T (temperature) 20° t (time) Hot Air, Cold Body • To confirm suspects’ alibi, time of death must be determined. • A healthy human being retains a normal body temperature of 98.6°F. • It was determined that the window for the time of death was between 4 and 5 pm. 100° 70° 30°
