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 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 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 task is designed to assess how well students understand ratio and areas.

A diagram is shows a circle with one square inside and one square outside, both just touching the circle. The first task is to work out the ratio of the areas of the two squares.

A circle is then inscribed inside of the...

In this activity, students are presented with a series of different sized equilateral triangles each containing a number of circles, each of radius one unit. Students are required to find the exact area of each triangle.

The activity is extended into three dimensions by considering the volume of shapes...

Produced by the Maths Magic project, Circles with Whole Number Points provides teacher inspiration for investigating equations of a circle and Pythagoras’ theorem. The student task sheet refers to the use of Geogebra. The task consists of drawing circle, centre (0,0), radius 5 and finding all the points with...

This simulation allows students to build circuits with capacitors, inductors, resistors and AC or DC voltage sources, and investigate current and voltage.

Sample Learning Objectives include: *Build circuits from circuit diagrams. *Use an ammeter and voltmeter to take readings in circuits. *Discuss basic...

Work done in this Nuffield 13 - 16 module followed from the B unit called ‘Magnetism and electricity’. This S unit provided enough material for eight double periods during a single-certificate science course. The teachers’ guide included eight worksheets to supplement...
