Happy 14th B'ak'tun!
Happy 14th B'ak'tun!

Luckily, we’ve passed 12/21/2012 and the world is still here and we’ve made it into the start of the next Mayan calendar cycle ... the next B’ak’tun.
The ancient Mayans had an interesting number system and phenomenal ability to guage time and planetary motion. Let your students learn a little more about this area of the Americas and their numerical skills as you study what all of the "end of time" fuss was about. Students review working with base 10 and learn about working with base 20 ... sort of. Enjoy the math and the history.
