This sequence of lessons (roughly three) focuses upon the functions of money and specialisation/division of labour. There is also some reference to reasons for trading.
Resources included are:
Exemplar student answer for essay question and annotated mark scheme
Clear, colourful and engaging PowerPoint which links to the worksheets.
Worksheets that match-up with the slides and clearly link to the specification.
Edexcel-specific set of notes for the student (and teacher!).
All resources are an original creation, detailed and very thorough. These lessons focus specifically upon Edexcel A Economics, but the fundamental premise could be applied to any exam board.
