A garden has the shape of a right-angled triangle. A fence goes from the corner with the right-angle to a point on the opposite side. How long is the fence?

Can you minimise the amount of wood needed to build the roof of my garden shed?

Do each of these scenarios allow you fully to deduce the required facts about the reactants?

Using compass points, can you describe up to ten paths on this map so that you bring as many gems back home as possible?

Eight lines are drawn in a regular octagon to form a pattern. What fraction of the octagon is shaded?

A number N is divisible by 10, 90, 98 and 882 but it is NOT divisible by 50 or 270 or 686 or 1764. It is also known that N is a factor of 9261000. What is N?

Introducing and developing STEM teaching in the classroom.

These tasks give learners chance to generalise, which involves identifying an underlying structure.

This feature will help you build up to generalising and, ultimately, proving.

Generalise the sum of a GP by using derivatives to make the coefficients into powers of the natural numbers.

Charlie Gilderdale discusses ways to encourage students to learn to function mathematically and use higher order thinking skills.

Sets of integers like 3, 4, 5 are called Pythagorean Triples, because they could be the lengths of the sides of a right-angled triangle. Can you find any more?

Can one example help us to perceive the generality?

Dip your toe into the fascinating topic of genetics. From Mendel's theories to some cutting edge experimental techniques, this article gives an insight into some of the processes underlying. . . .

This lower primary feature brings together activities which make use of geoboards.

This feature brings together activities which make use of a geoboard or pegboard.

This practical challenge invites you to investigate the different squares you can make on a square geoboard or pegboard.

Explore what happens when you draw graphs of quadratic equations with coefficients based on a geometric sequence.

Each interior angle in a quadrilateral (apart from the smallest) is twice the previous one. What is the size of the smallest interior angle?

This series of three articles discusses the development of geometric thinking.

Trigonometry, circles and triangles combine in this short challenge.

These articles, written for primary teachers, offer guidance on the teaching and learning of geometry.

This article offers advice on solving STEP and other advanced mathematics examinations geometry problems.

This article (the first of two) contains ideas for investigations. Space-time, the curvature of space and topology are introduced with some fascinating problems to explore.

This is the second of two articles and discusses problems relating to the curvature of space, shortest distances on surfaces, triangulations of surfaces and representation by graphs.
