More Decimals and challenge postponed

First, I will have the next challenge ready for Monday, so please check back for that.  I have to get the coins and can't make it to the bank until this weekend to get the "supplies."

Side question, what's different if you flip a penny from before 1982 and one after 1982?  Listen carefully when you flip them to get the answer.

After being in class this week we are able to add, subtract, multiply, and divide decimals.  

More to come later, also check out the upper right to see a new link to rush hour from math fun night.
