  Society is changing, has always changed, and will keep changing. However,
changes are becoming faster and what used to happen between generations, now
happens in the same generation. Computing Science is one of the reasons for
this speed and permeates, basically, every other knowledge area. This paper
(written in Portugu\^es) describes, briefly, the worldwide initiatives to
introduce Computing Science teaching in schools. As the paper's main
conclusion, it is essential to introduce Computing Science and Computational
Thinking for kids before they enter into a university.
