UCLA Olga Radko Endowed Math Circle

10/9/2011 -- Early Elementary Circle: Meeting 3 (Melinda Speckmann)

This week we will be working again with balances but children will need to use reasoning to find a fake coin among a group of real coins with the help of the balance. They need to be able to understand the difference between worst/best case scenario and how the fake coin will not always be in the same place.
