This collection comprises of twelve sets of GCSE examination papers. They are in the styles of the AQA, Edexcel and OCR linear and modular examinations for the 2012-16 curriculum. These foundation and higher tier sets of papers are all accompanied by suggested mark schemes. They are suitable for practice...

This Catalyst article looks at how an internal biological clock within every cell of the human body helps to co-ordinate and organise human behaviour and metabolism into approximately 24-hour rhythms – allowing organisms to synchronise with, and anticipate, day and night. When the body clock is disrupted in humans...

Three advanced level lesson ideas from Susan Wall designed to explore the properties of circles and their equations. Each activity is accompanied by teacher notes suggesting how the activity could be delivered and possible extension ideas. The first activity requires students to match the equations of circles to...

This resource consists of four interactive excel files dealing with the circumference and area of circles and some of the main circle theorems.

This SMILE resource contains two packs of games, investigations, worksheets and practical activities supporting the teaching and learning of circle measurement, plus two other related resources.

Circle measurement pack one contains nine work cards with a wide variety of activities covering...

This task is designed to assess how well students understand

The initial problems shows a black circle with radius 2r, inside of who two smaller circles of radius r are drawn. Students must show that the fraction of the diagram that is black is equal to a half.

The initial problem is altered with four...

Act 1

A square and circle are shown. Initially the square...

This resource contains eight problems requiring students to explore the equations of a variety of circles. Many of the problems are open-ended in so much as there is not a specific answer. These problems present the opportunity for rich discussion as students attempt to justify their solution. Students are required...

This resource contains six activities for use in the classroom when exploring the properties of circles.

The Circle: Contains a variety of questions requiring students to calculate the circumference and the area of circles. Given values for the diameter or radius of the circle. The second...

These 15 instant maths ideas, ideal for use as starter questions, extension question or probing questions to assess understanding, require students to perform a practical experiment in order to estimate a value for pi, describe a circle over the phone, find a connection between the length of the radius of a circle...

This Excel file has a series of sheets which illustrate the link between the equation of a circle and the corresponding graph. It goes on to deal with the intersection of a circle with a straight line.

The first...

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...

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

Circles and Cylinders covers, an introduction to circles, naming the different parts of a circle, estimating the circumference of a circle, eatimating the area of a circle,...
