O.R.E.O.
Our Really Exciting Online
Project
2007

Jennifer Wagner is once again adding a sweet touch to learning with her O.R.E.O. 2007. This project challenged us to see how high we could go, as we predicted, practiced number strings, worked with calculators, and were introduced to the world of balance and averages!

Our Assistants
We recruited four of our terrific parents to help with our project. Right: Mindy Davin

We thank them SO much! We couldn't have done it without them!

HOW HIGH CAN WE STACK OREOS? READ ON TO FIND OUT...
Our Work
How high can we stack oreos?

This was our first question to ponder. Each student took turns completing a chart of names and predicitons at his/her table.

The Stacking Begins

Everyone would have two attempts to see how high s/he could make the stack. Careful observation of others' attempts could help us when it was our turn again.

How high?

Andre certainly did a great job with his stack (right), but it couldn't beat our highest - 26 by Carl!

The cookie tumbles!

Of course, no matter how hard we try, there is going to be the inevitable tumble - which is just what happened as I tried to capture a picture of Sarah's stack!


Table Number Strings and Table Counts
After each student had two attempts, it was time to circle each person's best (highest).
Next number strings were written for the table and the sum found with the help of calculators.

Class Number String and Class Average
Once each table had found the sum of their best stacks, it was time to make a class number string.
Here it is:
92 + 91 + 108 + 75 = 366

Our final step was to find our class average by dividing 366 by 19 (the number of children stacking), which happens to be what our class average was - 19.

Explaining averages to second graders can be challenging, so to help them "see" what an average is I asked each person to write her/his best attempt number on a sticky note. Then we ordered ourselves from the least to greatest number. Here is our order:
14-15-15-16-16-16-18-18-18-19-19-20-20-22-23-23-24-24-26
What did we find? We found that 19 was right in the middle!

There will be more Math, too, as we use our predicitons and attempts to learn about
> greater than and less than <
as well as a challenge to find the differences between our predictions and attempts.

Let's Practice Greater Than/Less Than

Listen to a fun song about greater than/less than

Thanks, Jen, for another educational and fun-filled project!
