This is a nice introduction to macro economics and a good session for students who are thinking of taking economics at A level or GCSE.
The PowerPoint is designed as a conversation starter - used to introduce the macro objectives and discuss what they mean/their importance.
The A3 sheet can be filled out separately or during the discussions. Ideally in groups to encourage sharing of ideas and a group work element to the session (rather than one sided teacher talk).
The main interaction will come from teacher examples and highlighting the macro objectives in real world application/scenarios to get students engaged,
