In this project, classrooms around the world try to stack as many OREOS as possible.  Students first make a prediction about how many they think they will be able to stack and then they have two tries.  We had Skype conversations with two classrooms, on in the USA and one in Canada about our OREO stacking technique.  This activity fit into our unit on Data Management as we used tally marks to record our results.
