Topic: MS4.1 Perimeter and Area
Uses formulae and Pythagoras’ theorem in calculating perimeter and area of circles and figures composed of rectangles and triangles
Area and Perimeter Interactive
Investigate the perimeter and area of triangles, rectangles, parallelograms and trapeziums. Dimensions of the shape can be change to create many questions.
Bablyonian use of square root of two
Photographs and analysis of an 1800 BC Babylonian table showing the diagonal of a square and ancient knowledge of the value of square root of two – expressed in base 60. A great extension resource. No previous knowledge of Babylonian required, but will make more sense if students know about different number base system. Full mathematical analysis on the site.
Bronowksi demonstrates Pythagoras Theorem
From the 1973 BBC Series “The Ascent of Man”, Bronowski travels to Samos and shows how Pythagoras’ Theorem can be demonstrated geometrically. Students could be asked to replicate the proof after watching.
Buffon’s Needle simulation to generate Pi
A high quality Flash Animation to demonstrate Buffon’s Needle Theorem. Fire it up on your IWB and leave it running for a good while to get closer and closer to the value of Pi.
A great resource to use when introducing students to the surprising mathematics involving Pi.
Cell Phone Maths
An interactive whiteboard resource to encourage students to apply their maths skills to the real world. 2 types of real world questions can be generated by the resource: percentage discounts and area.
Exploring the Diameter and Circumference of Circles
This multimedia mathematics resource demonstrates how circles can be found all around us. An interactive activity allows students to explore the value of pi by investigating the relationship between circumference and diameter. A print activity is provided.
