Pair Share with a Twist
Topic Index | Algebra Index | Regents Exam Prep Center

 

Teachers are always eager to find news ways to engage students in meaningful activities.  The concept of "pair-share" sounded like a wonderful activity for engaging my students.  As with many things, I found the theory of the pair-share to be slightly different from the reality of pair-share at the high school level.

In a traditional pair-share, one student solves a problem and then waits for the partner to solve the corresponding problem.  Well, you guessed it -- teenagers wait for no one!

So, in an effort to maintain the idea of the pair-share, I added a twist.  Students can solve THEIR side of the worksheet as quickly as they wish.  The "hook" is that when both students are finished, they will have the same answers - but NOT in order.  A score of 100 requires the correct answers in the correct locations on BOTH sides of the paper.  This method creates an atmosphere where students actively discuss their solutions.  Mission accomplished!
