Certain schools on the Yucatan Peninsula in Mexico are teaching native students the mathematics that was done by their ancient ancestors in the Mayan civilization. Check it out in the video above.

Watch the video and pay attention to how the Mayans write their numbers and conduct simple arithmetic. Answer the following questions.

How would you express the number 19 using the Mayan notation?

In the video, the news reporter shows how to do the arithmetic 16 + 7. Replicate that arithmetic using drawings.

Now create a drawing/notation using the Mayan method to conduct the arithmetic 18 + 6.

Explain at least three reasons why it is important for these children to be taught this method of arithmetic alongside the “typical” methods (like the way you learned to do addition, for example).
