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.
WEWE’’VE GOT A VE GOT A MURDER ON OUR MURDER ON OUR
HANDS!!!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.
Tracks of a KillerTracks 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.
Hit and RunHit 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.
Dropped at The Dropped at The SceneScene
• 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”.
Suspect RadiusSuspect 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.

Hot Air, Cold BodyHot 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.
