A science teacher’s presentation of scientific numbers
How a science teacher presents scientific numbers – presented by a young energetic science teacher. Could either show the video or “borrow” the ideas on showing mass of the sun and mass of a proton as your lesson hook. Good question at the end for students to work out.
Adding fractions (animations)
Flash animations that show how we add fractions. Clear animated diagrams promote understanding and correct mathematical working is also demonstrated and explained. There are step-by-step explanations that can be turned off if you are presenting to a class. Free.
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.
Dividing decimals (animations)
A set of clear animations that explain division of decimal numbers. Recurring decimals are also included.
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.
Fraction Comparison
An interactive whiteboard resource. The students have 30 seconds to show which of a pair of fractions is greater than or less than the other by drawing on the appropriate signs.
Investigating Scientific Notation
An investigation of some real objects using Wolfram Alpha. The worksheets formed the basis of the investigation looking at the mass of a grain of rice, the diameter of the earth, the speed of light and the distance to Proxima Centauri (the star closest to earth).
