Prime, Composite, and Square Numbers

What happens when you give a group of fourth graders the challenge of teaching others about prime, composite, and square numbers?  Of course they create an educreations presentation!
 

The students in Ms Scott's class have been studying Factors in Chapter 2 in our new math program, Math in Focus.  They all did a remarkable job explaining these 3 types of numbers.
