This is my favourite way to introduce Pythagoras to students. Included is a worksheet with the required pieces, the larger one for students to cut up and rearrange, the smaller one to stick in whole to write notes about what they have discovered. The PowerPoints give the instructions for how to cut up the larger shape and what to do and then the answer and the explanatory notes that lead to Pythagoras' Theorem
The skill is to use a source for information and to develop the skill of using evidence from sources.
Starter activity of an 'Inference Grid&' - to develop the analysis of sources. (This is also available, here, as a powerpoint presentation). Main activity - Card Sort entitled ‘Causes, Symptoms & Treatments’, deciding what card goes where. Plenary ideas - &';post-it' notes on A3 sheet - labelled &'Causes, Symptoms and Treatments&';.
There is also a worksheet, entitled 'Symptoms of the Black Death&' to use as an extension activity of for homework.
