Question from Loulou, a parent:

Joe and Chris each bought a six pack of cola. Joe gave 2/3 of his away and Chris gave half as many as Joe. how many more colas did Chris have than Joe

Hi Loulou,

The question is about thirds so ask Joe to place his cans of cola into three groups of equal size. How many cans are in each group? Joe gave away two of his three groups. How many cans of cola did he give away? How many does he have left? Chris gave away half as many. How many did Chris have left?
