### Keeping Baby Warm

This Cre8ate maths activity investigates the ratio of surface area to volume in adults and babies and explains why we keep babies wrapped up in winter.

To calculate surface area and volume students make scale models of a baby and an adult. The models may be simple in nature, such as a single cuboid, or a...

### The Argand Diagram

This MEI interactive resource for complex numbers demonstrates the Argand diagram.

This flash file can be used to plot a point in the complex plane. In this plane on the horizontal axis are the real numbers and on the vertical axis are the imaginary numbers. The point can be picked up and moved into all four...

### Measuring

This Subtangent activity uses information from the Hubble space telescope to emphasise the need for accurate measurements and the costs involved when things go wrong.

There are demonstrations of measuring lengths and angles before asking the students to try for themselves.

An interactive ruler and...

### Rotational Symmetry

A simple animation from Subtangent presents examples of rotational symmetry in nature and demonstrates how to establish, using a centre of rotation, the order of rotational symmetry.

Students are given five shapes and invited to investigate their symmetry.

### Differentiation Exercise

This interactive resource, produced by the University of Leicester, is designed to enable students to explore the differential function of a polynomial and conclude by forming a generalisation.

An instruction page explains to students that they should draw a polynomial. Then by sliding the slider the...

### BP in Business Case Studies

This case study from BP Educational Service offers students aged 14-19 an insight into how a global business works. The study explores how BP's marketing team decides on place of sale, price and promotion for a product.

This resource is also suitable for Business Studies students.

### Manipulating Surds N11

In this resource from the DfE Standards Unit students identify equivalent surds and develop their ability to simplify expressions involving surds. Students should understand what a square root is and be able to remove brackets correctly. (GCSE grades A-D; AS and A2 level)

### Using Indices N12

In this resource from the DfE Standards Unit students are introduced to fractional and negative indices to enable them to evaluate numerical expressions using negative and fractional
indices and use the rules of indices with integer and fractional powers of variables. Students should have some knowledge of...

### Analysing Sequences N13

In this resource, from the DfES Standards Unit, students learn to define a sequence using the
general form of the nth term, define a sequence inductively, recognise and define an arithmetic and a geometric progression and to reflect on and discuss these processes. Students should have some understanding of...

### Interpreting Distance-Time Graphs with a Computer A5

In this DfE Standards Unit resource, students interpret linear and non-linear distance-time graphs using the computer programme Traffic. This program provides a simple yet powerful way of helping learners to visualise distance–time graphs from first principles. The program generates situations involving...
