This activity is based upon addition and subtraction of integers, requiring students to find patterns and relationships, develop formulae and prove results.

The resource consists of printable worksheets, teachers' notes and solutions.

The activity can be extended by the use of algebra to explain...

This lesson develops the concept of adding and subtracting directed numbers. The activities address common misconceptions about the addition and subtraction of directed numbers. Students explain their reasoning using diagrams.

The activities use the ‘charge’ model of directed numbers. For example, a diagram...

A number line is used in this resource, from the Centre for Innovation in Mathematics Teaching, to illustrate how to solve a calculation involving negative numbers. To help correct misconceptions regarding these, the term taking away is used to represent minus and giving back for plus. Thus -8 +6...

This SMILE resource contains three packs of games, investigations, worksheets and practical activities supporting the teaching and learning of addition, ranging from simple number bonds to dealing with decimals in context.

Addition pack one contains fifteen work cards with activities on...

This activity, from the Institution of Engineering and Technology (IET), looks at how the boomerang works from design and scientific principles. Students explore how aerodynamic forces affect the flight of objects, relate the design features of the boomerang to its path...

In this activity, from the Institution of Engineering and Technology (IET), students explore the basic principles of aerodynamics by looking at familiar products that have been designed with speed in mind and identifying features common to these products....

This More Maths Grads resource, from the Maths Careers website, investigates the maths used in transport and is based on the travelling salesman problem.

Students are given a table containing information on the cost of air travel between nine different cities and asked to plan a route that visits each...

This engineering resource, produced by Mathematics in Education and Industry (MEI) for the Royal Academy of Engineering, asks the question: how can a camera, mounted on a helicopter, be used to track the location of a ground-based object? A number of discussion ideas are considered before using 2D and 3D...

Designed to improve confidence in mathematics, these resources from the Centre for Innovation in Mathematics Teaching, focus on algebra and were developed particularly for primary teachers and those non-specialists who teach mathematics in the lower secondary years.

Each section offers an overview of a...

The first of four RISP activities, Exploring Pascal's Triangle...

These National Strategies study units are for individuals or groups of teachers who are considering their teaching of algebra at Key Stage Three.

Unit 1: Using a grid method to multiply expressions - This unit discusses ways of using a grid method to help students to multiply a single term over brackets and...

This MEP resource from CIMT is taken from text book 8A which covers the mathematics scheme of work for the first half of year 8.

Algebra: brackets covers: expansion of single brackets, solving linear equations with brackets, finding common factors leading to simple factorisation and expansion of two...

This MEP resource from CIMT is taken from text book 7B which covers the mathematics scheme of work for the second half of year 7. Algebra: linear equations covers fundamental algebraic skills such as substituting numbers in expressions, the use of function machines and solving simple linear equations. The initial...

This MEP resource from CIMT is taken from text book 9B which covers the mathematics scheme of work for the second half of year 9.

Algebraic manipulation covers: the difference between equations, formulae and identities, solving equations, using formulae and testing for identities. The topic continues by...

Alien Invasion is a set of four interactive lessons about a full-scale alien attack that coincides with a class visit to Manford City. To set the scene and support the lessons, live television news bulletins, radio broadcasts and telephone messages help to develop the story line. The invasion leads to a series of...
