This presentation contains a whole lesson! Focus is on the additional purely A-Level topics that are not covered in IGCSE. This covers the Edexcel specifications, but maybe worth checking if you use a different specification for A-Level.
Specifically this lesson is for teaching ... marginal propensity to consume. It focuses mainly on the calculations, but also a bit of theory behind it. Most of the theory in terms of fiscal policy I teach in separate lessons. The mathematics is not the easiest especially for those who don't have a maths background.
I have used the PowerPoint slides to structure the lesson, specifically slides to prompt/force myself to ask those key questions at the right moments, slides to explain keywords with short and easy explanations, prompts for me the teacher when to use the different activities, games, handouts, articles etc... that make the lesson up as. All the teaching presentations, include starters and plenaries, normally a quick discussion, but sometimes something else and differentiated learning objectives. ALL 82 LESSONS are available as ONE BIG BUNDLE !!
I have to say that there is an excellent video on MPC done by the Khan Academy, which is also worth checking out and may be used in conjunction with your teaching.
