After students have had practice with operations with polynomials in Algebra I, we completed this speed dating activity.  Each student was given an index card with a different expression.  They then had to find a partner and complete the given operation for their two expressions.  You could also have them meet in a group of 3 to complete more complex operations.  This was a quick and engaging way for students to practice the operations with different students while having fun.

A great follow-up that I used after this activity was this quizlet by amberlyroberts:  https://quizlet.com/_6wbp92?x=1jqt&i=1box8n

I had students work on this when finished with their speed dating review.
