WCYDWT (What can you do with this): How Big is the Gorilla?

Here's a good slide to show to start a conversation about decimals with your class. The first question that comes to my mind is: So, really, how big is this gorilla? What are some of the questions that come to your mind?

Most textbookish review sections for decimals are pretty boring. How might this help? Putting a common idea in a interesting, surprising way will get the kids attention. Now how do achieve your math objective with that?
