It’s time for the OREO Project! This project connects us with other classes around the country and world who are talking about math using OREO cookies.

This year we divided into four groups to do our two official attempts at stacking, then just for fun we did a round-robin style tournament where the winners from each group went against each other. Congratulations to Darren, the winner of the tournament!

Then we did some calculations about our results. We determined that the mode of our data was 18, the median was17, and the mean was 16.65. Our highest stack overall was 20. In Mr. Maijala’s class next door, the highest was 22. We’re going to have to ask them about the techniques they used to get their stacks higher!

In our groups we did some more math with the nutritional data of Oreos. Did you know:

- There are more calories in a serving of regular Oreos than in a serving of Double Stuff. However, if you read the package carefully, you’ll see a “serving” of regular Oreos is 3 cookies, while a serving of Double Stuff is only 2!
- There are approximately 2,800 calories in an entire package of Double Stuff Oreos. That’s about 40% more calories than you’re supposed to eat in a whole day!
- A serving of regular Oreos contains 10% of the daily requirement of iron. You’d have to eat 30 cookies to get your whole daily requirement—probably not a good idea! We noticed there is more iron in regular Oreos than Double Stuff, so we assumed the iron must be in the cookie part and not the filling.
- One serving of regular Oreos contains 8% of the daily allowance of sodium. If you ate 12.5 servings, or 37.5 cookies, you would reach 100% of your daily allowance of sodium.

Many of us in this class did the Oreo stacking two years ago, and we noticed that our stacks this year were overall much shorter than the ones from that year; we had several stacks of over 20 that year and our highest was 25. We wondered why that was. Do you think something about the cookie design could have changed in the past two years? Some of us thought that we are just less patient than we were when we were third graders! We’re curious to watch the results page and see how the data from other classes matches our results.
