The O.R.E.O. Project


OREO project

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?


  1. This looks really neat!! I wonder who can make the highest stack! Did you guys get to eat the oreos to?


    • no we didn’t but i wish we did we didn’t eat the oreos because so many people touched the oreos and miss.Hamman didn’t want any people getting sick.thank you

      i love you

  2. Wow! That look like such an exciting activity, and well done to the student who stacked 26 Oreos, that’s a very impressive total.
    We eat Oreos in the UK too, but I think they are more popular in the USA.
    I hope you were allowed to eat the biscuits as reward for all your hard work!

  3. I remember doing this with my class. You had some really great stackers and I love how engaged the students were while others were stacking. I hope to blog with my class and maybe we can pen pal some things together. My school is in a suburb of Chicago. Great job to all the students!!!!!

  4. I really like what you have done with the Oreo project I like the idea of staking the oreo’s

  5. I like the maths lesson. I wish we did it to! I don’t know what the most poplar sweet/snack is. I look forward to blogging with you.

  6. Great job to all the stacker’s and how involved everyone was. I don’t recall learning to graph this way, but maybe we will have to practice this way at home.

  7. I really like the Oreo prodject I like Oreos so much!!!
    It is really cold her and my name is India bye!!!

  8. Hi I’m Jodie I am really excited to get quad blogging. I don’t actually like Oreos but I would love to have a go at stacking them up. I wonder how many Oreos I would stack up?

  9. Hi I’m Sophie I’m really excited to get started with quad blogging and I’m looking forward to learn about what your learning about this time also I like the idea of Oreo stacking and I’d like to find out how many Oreos you got in the end.

  10. Like the o.r.e.o stacking guys . My name is Alfie. Do you wish you ate the o.r.e.o.s … What grade are you in?

  18. Hello Mrs. Hamman and students!
    After our Skype conversation with you about the differences in our weather, we decided to go outside and take some pictures of what fall looks like on the Eastern coast of our country. We posted those pictures along with our favorite fall activities here.
    Hope you like them!

  19. Dear Mis.Hamman’s class,

    My name is Madison. I am in Ms.Myers class. I think that is a lot of Oreos. How many did you stack? My class stacked 28 oreos. Who had stacked the most in your class? I got one more question what was the hardest part of stacking? What did you do to get a lot? if you do i will be happy.
