Measurement

When we studied non-fiction, one type of fact we learned about was the comparison fact. 

One day during our math stations, a group measured themselves with gingerbread (practicing measuring in different units) and discovered one of them was 18 gingerbread.  Then he measured the top of our table.  It was 18 gingerbread.  He shared with me that he was as long as the table.  Thought we could try it out and sure enough...he was pretty close!
