Mrs. Peterson has green, orange, yellow, and red M&M’s in
her office. She groups one of each color to make sets of 4.
She has a total of 12 M&M’s. How many orange M&M’s does
she have? How do you know?
 3
 16
 8
 4
I can see that I have 12 m&ms
total. I can see that in groups
of 4 I would have 3 of each
color, so I can prove that I
would have 3 orange.
