This is the first of a four-lesson series on proportion, which is also bundled together with two lessons on ratio at a reduced cost. This is a new more important focus area for the new 9-1 GCSE.
This lesson looks at exchange rates, exchange rate graphs and conversion graphs. It also includes a starter, plenary, plenty of excellent teaching slides, learning objectives and keywords. It also focuses on the difference between ratio and proportion (as most don't seem to know) and a matching activity to re-enforce that.
