A diagram is shown with a circle, centred on a rectangle with given dimensions.  Semi-circular arcs are drawn with the sides of the rectangle as diameters. The areas between the semi-circles and the circles form crescents. The task is to calculate the area of the crescents.

When working on the numerical...

This activity is based on the work being carried out at The University of Oxford where researchers are using x-ray tomography (CT scanning) to visualise and measure the 3D structures of fossilised organisms that are still encased in rock.

This resource, from the Maths Careers website, explores fractal geometry and was created in conjunction with More Maths Grads and the University of Leeds.

The activity involves making paper representations of fractals and gives the opportunity to investigate some of their mathematical properties.

The games, with their mathematical content, are: *Three in a row - strategy game using division with decimals *Halves...

Fraction Matcher gives students the opportunity to explore the concept of fractions. The “Fractions Screen” contains eight levels of matching fractions using fractions less than one up to improper fraction representations for fractions greater than one. The “Mixed Number Screen” concentrates upon fractions greater...

This resource from Defence Dynamics help students to understand the process of fractional distillation in the context of crude oil distillation. In the first activity, students consider the physical properties of different oil fractions. They then compare their boiling ranges and examine the relationship between...

The Fractions (General) resource here contains nine instant maths ideas exploring what is meant by a fractions, showing fractions by shading using squared paper and isometric paper, exploring what fraction of words are made up of one letter and investigating why some cancelling does work and others do not. There...
