8 Summer 2 Lesson 6


Description Crime Scene Investigation
This task uses a Problem-Solving Approach and is designed to take approximately 4 hours of teaching time.
The resource enables teachers to lead pupils through a crime investigation to help solve the problem of ‘whodunit?’ A theft has occurred and the only clue to identify the culprit is a footprint.The students work through the data handling cycle:

data cycle

Pupils will investigate how helpful the footprint may be in identifying the thief. They will use averages as well as histograms and scatter diagrams to explore the likelihood of various suspects being the culprit.  

As they may not have done averages since year 7, you may want to do some recap lessons (or use the year 7 lessons).

This will need varying amounts of scaffolding depending on the students within the group.  A writing frame would be useful to direct some students.
Data is available that has been collected from the Census at School website, for each of the ages.  The data is split by gender too.
Templates could also be used for putting data into frequency tables to make the process quicker.
If working in groups, you may have different groups working on different ages, and then comparing their evidence at the end.
