dueling speakers


You are attending a teachers' conference focusing specifically on division of fractions.  

The first speaker says:  Here is an example for dividing:  I have  ft of lumber and I cut it into   foot-sized pieces, how many pieces can I make? (In essence:  How many  make ?)

The second speaker says:  Here is an example for dividing:

I have  ft of lumber and need four pieces. How long will each piece be?

Which speaker is right?

Identify each of their approaches to division and draw a corresponding
visual model.

   

Submit your idea for an investigation to InterMath.
