Shows like 6! Setzen - Das Wissensduell Groß gegen Klein

There are 1 teacher (the host), 6 students (children aged 8-10 years), 3 socialites, and 600 grown-ups in audience in the "classroom". In every round, one student fights against one grown-up (always a socialite and a grown-up from audience in change) and both have to answer the questions which the teacher asks. If both have the right answer, then both win 2,500 Euros for his account. If only one has the right answer, he wins 5,000 Euros. The other one has to sit down and "gets" the school-grade 6 (US grade: F). If both give the wrong answer, it happens the same "sit down - 6", but they can save their money, if his team has given the majority of right answers. Then, in case of the contestant has to sit down, it's the next team member's turn. But further there is also a joker, to crib from another team member, he takes his answer without the knowledge, if this answer is right. When all 20 questions are answered, this team with the most money wins the match, and both teams get their own gained money for their project.
