What To DO With a Handful of Pennies? Measures of Central Tendency

 
 
 
A good icebreaker to use when introducing Measures of Central Tendency (Mean, Median, Mode, etc) is to grab a handful of pennies from your vehicle and lay them out on a table and have your students work in groups to place them in order of date from least to greatest (if you have a large class you may need multiple handfuls of pennies).  
 
Next, start collecting data.
 
Mode can easily be seen by the largest stack.
Median, Range, Q1, Q3, IQR can also easily be found
Mean is slightly tougher unless you allow your students access to a calculator
 
Next, have your students create a dot plot of the data
 
Finally, have your students pick 5 pennies for their homework. Tape the pennies to their worksheet so that they can read the date (see pic below).
