Old Dominion Freight Line is offering 2 free tickets to the next 3 World Series to the person who guesses closest to "How many baseballs are in this truck?". The contest end August 31^{st}, so do your figuring soon and submit your guesses. You need to be 18 years or older to enter, so get help from an adult. Submit your guesses here: Seats to the World Series Sweepstakes.

We have created a math activity so that students can reason and apply math to solve a true real world problem. Plus, they get to refine their estimates and increase their chances of winning World Series tickets! This could be a great way to get kids working together on an engaging problem early in the school year. Enjoy!

For members we have an editable docx, our Excel sheet of calculations, and solutions/tips.

*Caution: We don't know the winning solution. If we did, we wouldn't tell you! We've shown a few solution methods and a reasonable range of possible asnwers.
