Sieve of Erathostenes (ESO 1st Course)

Pedro García Gil, a very interesting bilingual maths teacher suggested me this activity, I changed only a little bit. It is a worksheet to work in pairs.

• Sieve of Erathostenes.

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

Making experiments with probability (ESO 3rd Course)

After the unit about statistics, we were working with probability. I found a really interesting activity in order to understand the law of large numbers. It consist on making experiments with one die and two dice. Here you have the links:

• An experiment with one die
• An experimient with two dice

The students worked in pairs, they were writing the result of their experiments and finally they gave their work to the teacher. It was funny and  very learning too!
