Will I have enough stuff?

Thursday, Aug 10^th, is National S'mores Day!

In my pantry I have one new box of Graham crackers, one bag of 6 full-sized Hershey bars, and one bag of marshmallows. Friends are meeting me at the beach for a bonfire and s'mores. What do I need in order to make enough sweet sandwiches with not too much left over?

Another activity to celebrate National S'mores Day!

Largest S'more ever - To help celebrate this strange new holiday, we've asked students to do some figuring to help quantify what is reasonable.  How many marshmallows are in this recipe?  How many people could this cookie feed? How many marshmallows could you eat?
