Question

There are 25 students in Ms.Morris's class. She wants to divide the class into 3,4,or 5 equal teams with all students on a team. Which number of teams can Ms.Morris make? Explain.

Answer 1

Ms. Morris can divide the class into 5.
5 times 5 equal 25. 

Answer 2

5 equal teams:

3 doesn't go into 25 equally (unless you wanted to have a third of a child)

4 doesn't go into 25 equally (unless you wanted to have a fourth of a child)

5 goes into 25 equally 5 times, 5x5=25.
