Resourceaholic
Resourceaholic is crammed with ideas and resources for teachers of secondary school mathematics.
Finding the Area of Compound Shapes
A good site on finding the area of a shape based on rectangles on a grid. Estimate first and then compare with the actual area of the shape. Good as an IWB demo tool for teaching how to apply the formula to compound shapes based on rectangles.
Cassowary Fractions
Design some zoo enclosures for sick cassowary birds. Good practise for equivalent fractions.
Fraction Fiddle
A fraction game where you need to meet orders in a cake shop. Match customer orders written as fractions to cakes that have been cut into segments.
Coordinate Alien Attack
Thwart an alien attack by using your knowledge of coordinates. Select either coordinates in the first quadrant or use all four quadrants.
Part-Part-Whole
This teaching tool is useful for demonstrating 'Part-Part-Whole Model' for addition and subtraction particularly on an interactive whiteboard. Select which manipulatives you want to use and easily change your choice by pressing the 'change' button.
Classifying Triangles by Angles and Sides
A video tutorial from PBS on how to classify triangles according to angle measurements and side lengths. It is likely to appeal to pupils because it is presented by a student.
Virtual Unifix
This is a manipulative which has virtual Unifix which can be snapped together. Better on desktop machines than tablets. Poor on iPad.
Spinner
Spinner is an interactive resource for generating random numbers up to 10. You can reduce the number of segments. Try this for generating equations.
Measuring Area
An animation from the BBC covering the concept of area, and different ways to measure and calculate the area of rectangles, triangles and composite shapes.
