Behaving exactly like the Commons people do
The Opposition's job is to scrutinise policies put forward by the Government.
Your Opposition will oppose the Government's idea. A main spokesman will put forward up to five points against it. As with the Government the rest of the Opposition can support their spokesman's points.
The Speaker must remain impartial during debate. Their job is to maintain order - this is Government not the playground. The child chosen to b the Speaker must be strong-minded and authoritative.Alternatively this could be the teacher.
The Government puts forward laws (the rules and policies that run our country). The Government chooses a spokesman to introduce a debatable issue with up to five main points in support. The Government has an even number of people to the Opposition. After the Opposition has replied, the rest of the Government can support their viewpoint via the Speaker.
This is the rest of the class. They are the undecideds and can be convinced by either side's arguments to vote one way or another.
Once the points have been raised the chair can invite questions from the undecideds. When there are no more questions to either panel the chair puts forward a vote from the undecideds who go to the 'no' door or the 'yes' door. Two children count the votes and the motion is either defeated or carried.
