Oreo Stacking Challenge

Today we did our Oreo cookie stacking challenge!  Our class average was 16 cookies stacked!  As of today, 10,680 students throughout the world have participated and the average number of cookies stacked is 18!  18 is also the average number for 2nd graders who did stacking.  We had fun doing this project.  We compared our prediction to our actual results and did a couple math problems too.  We have a couple other activities to do to finish the project but didn't have time today.
