For the second year in a row, our class is participating in the O.R.E.O. Project. O.R.E.O. stands for “Our Really Exciting Online” Project. It involves math, writing and making global connections. It also involves Oreo cookies!
First we estimated to predict how many cookies we’d be able to stack.Then we separated into teams to stack the cookies. The rule was that cookies must be stacked one at a time, and if even one falls over, the attempt is over. We each had two attempts, then we recorded our highest stacks. We made a spreadsheet and used it to make a bar graph showing our best attempts. We also calculated the mean of the attempts. Results:
The mean of our estimates was 25.
The mean of our towers was 21.
The greatest number of cookies one student stacked was 26.
We reported our results to the O.R.E.O. Project results page. Then we worked on word problems in our math journals that all related to Oreo cookies.
On Thursday we will be Skyping with Mrs. Schmidt’s class to compare our results. We have a few other classes lined up to Skype with over the next two weeks. We wonder which class will have the highest stack!
Here is a short video showing us stacking the cookies. Can you see that some kids tried some different techniques to get a higher tower?
Oreos are the number-one best-selling cookies sold in the United States. What are the most popular snacks in your country?
