This resource created by Shirley Fall has twenty mystery fact cards, each containing a statement about the features of straight line graphs and how they lie on a 3 by 3 grid. The rationale is for students to use the fact cards to discover the features of each graph - its gradient, its intercept, its graph and...

Straight Lines

This interactive file deals with...

This interactive excel program is about finding the equation of straight lines in the form ax+by+c=0. The first two sheets deals with the equation of the line through two given points and the equation of the line through a point perpendicular to a given line. The...

In this resource students are challenged to determine the equation of the line that goes through a given coordinate point and is also tangential to a circle centred on the origin. The final step is to determine the radius of the circle.

The solution involves determining the gradient of the tangent and also...

Two verticals masts on a horizontal base have ropes tethered to each other’s base. The challenge is to find the height at which the ropes cross. When working on numerical examples, it becomes...

Three addition calculations are shown using symbols instead of numbers. Can students arrange the symbols from smallest to largest? A second puzzle follows with four additions, including one with more than one symbol on each side of the equals sign.

Students are asked, in this resource from Defence Dynamics, to consider the importance of approximating and checking strategies in mental calculations and also of answers derived from a calculator. At each point they weigh up their answers against real-life results where unexpected factors have had to be taken into...

This Cre8ate maths activity draws on measuring stretchiness which involves the collection of real data, calculating percentages and experimental design. This resource models one way in which engineers use their knowledge of mathematics to investigate the properties of materials. Here students investigate the...

This guide, for more advanced users of LINUX, shows how BASH scripts can be used for operations on strings and for arithmetical operations. The syntax for BASH is clearly explained.

This is one of a set of resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within science, maths and design and technology. This resource focusses on testing how well different shaped structures perform under load.
