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.

Page 7: Math Day Murder Mystery

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”.
