We have been working in cooperative groups this week in math class.  Students have been working together to solve problems and explaining problems to each other.  This has been helpful since we have been working on converting units of measurement within  the customary system.  This can be a daunting task considering all of the different conversions that we have in our system (12 in.  makes a foot, but 3 feet makes  a yard, but we have 16 oz. in a  pound?! –to name a few)  I am beginning to see why most use the metric system!

What do you think of working in groups?  Are there advantages?  Disadvantages?
