Copy the problems onto different colored paper, one color per problem set
Cut the problems out and place into a ziplock bag or envelope
Place students into groups of THREE
Each person take out one problem of the same color out of your bag. Example is shown above.
Hold the problem to your head.
The person that is holding the bolded problem needs to add the other two polynomials together. This would be the third problem in the picture.
The other two people will check the answer and give help if needed.
Repeat previous steps until you run out of problems.
