In 2017, Old Dominion Freight Line offered 2 free tickets to the next 3 World Series to the person who guesses closest to "How many baseballs are in this truck?". Alas, the contest ended on August 31st, 2017.

We've created a math activity so that students can reason and apply math to solve a true real world puzzle.  

The math activity: How-many-baseballs.pdf

CCSS: MP1, 8.G.9, HSG.MG.A.1, HSG.GMD.A.3, HSG.MG.A.2, HSG.MG.A.3

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

Caution:  We still 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.
