Powers and roots (ESO 1st Course)

I haven't find many resources I thought interesting about powers and roots. And I finally had a problem when I tried to use them in class, because the computers need some plugins that are not easy to set up in the Guadalinex Laptops.

Anyway, here are the activities I would like have used about powers and roots:

• Game: Martian Math (Powers and roots)
• Activity: Powers and roots
