Teaching mathematics to children

Time and again grown ups want to teach mathematics to children and want everyone to get involved. There are plenty of funds for university professors to get involved and if you say that its not your career focus you are stigmatized big time. On the other hand if university professors are funded for getting involved in high school mathematics then they must teach a semester long course. That is the only way they make a real contribution. Just visiting schools and telling school teachers that they do not know how to teach is idiotic.
