Math Workbox: Twenty-One Elephants

In 1883, workers completed the Brooklyn Bridge, an incredible feat of 19th century engineering. Problem was, folks were scared to cross it. How did they know if the bridge would hold?

In 1884, circus legend P.T. Barnum crossed the bridge with 21 elephants to prove the span could withstand anything...even the likes of Jumbo. The story is told (and fictionalized to varying degrees) in two books, Twenty-One Elephants and Twenty-One Elephants and Still Standing.

I wrote up three Math Box Card activities for children to do after reading the books. Lessons include comparing/contrasting literature, problem solving/measurement, and history. You can download them, free! Enjoy and please leave me a note if you do the activity.


  1. Thank you for the free download and the books to go with it! Our daughter is a bit young for this but we will save it for when she gets older!

  2. Even though the cards are too advanced for my preschooler, the books sound fascinating. Thanks for sharing your ideas!

  3. My kids are too young for these activities also, but the books sound very interesting!

  4. What a great story - we'll have to find those books!


Thank you for leaving me a message. I love comments almost as much as I love chocolate! And I do LOVE chocolate. :)
