Maths KS3 / GCSE: Pythagoras
The short clip demonstrates the theory of Pythagoras by showing how to calculate the Hypotenuse of a right-angled triangle and by using numbers it proves that the triangle is right angled.
The clip progresses to show the practical applications of Pythagoras by calculating the height at which a ladder against a wall reaches, and solving the problem of what size TV will fit in a particular space.
This is from the series: Real Life Maths.
Teachers can use the video clip to demonstrate how to apply Pythagoras and help pupils solve potential exam questions.
The learners could be arranged in a carousel arrangement; where they tackle exam questions with different skills such as calculating the shorter side, and proving that a triangle is right angled.
Using the video clip as support, Pythagoras lends to a variety of practical solutions.
So we could place learners in groups of 3 and take pictures around the school; where they would have to solve problems using Pythagoras.
The learners could feedback in a presentation format to the class.
This clip will be relevant for teaching Maths at KS3/GCSE in England Wales and Northern Ireland. Also at National 4, 5 and Higher in Scotland.
This topic appears in OCR, Edexcel, AQA, WJEC in England and Wales, CCEA GCSE in Northern Ireland and SQA in Scotland.
