### Brackets

This resource contains two excel programs; ‘Removing and Collecting Like Terms’ and ‘Multiplying Out and Simplifying’, each containing a series of interactive spreadsheets designed to explore how to deal with brackets.

**Removing and Collecting Like Terms** begins with two...

### Finding a Formula

This resource contains three excel programs; ‘Chessboard’, ‘Chess Cube’ and ‘Painted Cube, each containing a series of interactive spreadsheets designed to explore situations requiring students to find a formula.

**Chessboard** is designed for the...

### Composite Functions

This excel workbook contains a series of sheets to help students explore different types of composite functions including linear, quadratic and reciprocal functions.

The first sheet allows students to input different numbers into a flowchart showing two different linear functions. Students work out and can...

### Conversion Graphs

This excel file starts with a series of five sheets which show conversion graphs involving metric and imperial measures for height and weight and graphs for money conversions. The two money conversions allow the exchange rate to be altered. Units used include stones, kg, feet, meters, miles and km.

There are...

### Formulae, Rearranging, Evaluating

This excel file contains a series of sheets which give practice in rearranging formulae and substituting values. Clicking on the subject of the formula reveals the rearranged form. The answers to the calculations are also available.

The topics of the formulae include dynamics, elastic strings, pendulum,...

### Circles - Equations and Graphs

This excel program contains a series of interactive spreadsheets related to the equation of the circle. The first sheets enable the student to alter the radius and centre of the circles centred at the origin and elsewhere. The program allows the student to view the graphs of the circles as they transform.

### Cubics (Factorising and Graphing)

This interactive excel program enables students to investigate cubic functions and the relationship between the factorised form and the graph.

The first activities require the student to use the factor theorem to factorise cubic polynomials and then to see the graphs. Alternatively students can toggle...

### Factorising

This resource contains two interactive excel programs which enable students to investigate cubic functions and the relationship between the factorised form and the graph.

**Factorising: Quadratics a=1**

This excel file gives practice at factorising...

### Gradient

This excel program contains a series of interactive spread sheets designed to explore the concept of a gradient of a curve.

The first activity illustrates that the gradient of a function, at a point P, is the gradient of a chord PQ as the length of PQ tends to zero. The equation of the quadratic can be...

### Graphical Solution of Equations

This resource is an interactive excel program to enable students to investigate the solution of polynomial equations up to cubics using a graphical method.

The program shows the graphs of cubic equations and the equivalent tables of values. There is a set of questions requiring students to solve equations...
