Dice game

This post is something different, because I would like to recommend a book titled:

WORKSHOP ON STATISTICS AND PROBABILITY: GAMES AND WORK TO STRENGTHEN CONCEPTS. 

In my opinion it is a very interesting and useful book for teachers who do not know how to approach the concepts of probability and statistics. In it we can find countless activities and their respective explanations.
It's a free download book, so it's perfect for teachers looking for new resources.  What I like most about this book is that it has activities for all levels, from primary to high school, so that our students can continue to use it for a long time.

After reading the book and displaying several postings written by teachers, I would like to recommend the following activity: 

Dice game.
The class is divided into groups of 5 students and each group is given a couple of dice. Each group pulls 5 times the pair of dice coloring on each occasion the result and being understood by result the sum of the scores of both dice. When finished, the results are counted and recorded in the boxes of the corresponding numbers at the top, so that the students see which numbers are more likely to appear. Then, the teacher will detail all the possible cases that this experiment has, showing the reason why the numbers 6, 7 and 8 have been obtained normally more than the others. It is a good exercise to introduce the concept of probability of an event.
To reflect also the why the first two numbers have never come out.
