This is a whole lesson specifically looking at how to increase or decrease by a percentage using a calculator. This is a classic more challenging exam question, involving real-life contexts like sales, tax, VAT, depreciation of cars etc... This builds on the understanding from lesson 3 and starts to look at the concept of the multiplier, which comes up in lesson 6 as well on compound interest. 15 slides + resources.
The lesson includes:
+ a starter
+ learning objectives
+ keywords (vital for lessons on percentages)
+ lots of excellent teaching slides
+ superb detailed examples
+ MWB activities
+ embedded questions with answers
+ specific exam questions as a worksheet with answers
+ helpsheet to support the least able (which looks great when being observed)
