Escape!

Escape the Classroom

Your entire class has been trapped in the classroom.  You must find the keys to escape.  Those pesky Aliens are at it again and have somehow put us all in the classroom.  Who can find the keys?

Just like when we lose our keys at home, let's retrace the steps Joe took and see if we can find where he put them.  He claims he lost them but I think he is laughing, or is that an alien burp.   

You followed some crumbs.  No really, actual crumbs. Argh... He has eaten some of the class' brownies! There was 2/3 of a pan here at the start of class (okay, Mrs. Frier can't resist a good brownie), and it looks like Joe ate 4/5 of that! What is left for the class?


And then he ate some pizza!  Gosh, he is a hungry alien.  

Now where did he put that key?
