This lesson develops the concept of converting between and ordering fractions, decimals, and percentages. The lesson uses area and linear models of fractions, decimals, and percentages to understand equivalence.

The main activity is a collaborative exercise. Students must collect together cards that show a...

This lesson develops the concept of translating between decimal and fraction notation, particularly when decimals are repeating. This is achieved by

• Creating and solving simple liner equations to find the fractional equivalent of a repeating decimal
• Understanding the effect of multiplying a...

The first two interactive sheets deal with selecting objects from two bags. The outcomes are shown on tree diagrams and the probabilities can be revealed.

The next interactive sheet deals with the problem of passing...

This activity is based upon a practical task to fit a set of similar triangles into a spiral. It is in two parts, the first of which is more accessible.

In Part 1 students are presented with a series of different sized similar triangles. These fit together to form a spiral and students look at how many are...

This task considers using metal rods to make a triangular framework. The metal rods have lengths that are whole numbers. Students must work out how many triangular frameworks can be made with the longest side being 7 metres. The solution involves being methodical in listing examples, and using inequalities to...

Produced by the Spode Group as part of the A-level mathematics support series, this booklet aims to show the practical importance of trigonometric functions. The booklet contains five case studies.

This short task contains two questions on applying trigonometry.

The topics covered are:

• Linking sine, cosine and tangent
• Using Pythagoras to determine a length in a triangle and then give the tangent of an angle in surd form
• Using the Pythagorean identity sin2(x) + cos2(x) = 1...

This resource is designed as a resource bank of questions to supplement the teaching element of the lesson. The questions require students to use Pythagoras' theorem in order to find whether a triangle is right angled and find the lengths of missing sides, and problems on 2D and 3D shapes.

The next section...

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.

Trigonometry covers: Pythagoras' theorem, trigonometric functions; an introduction to sine, cosine and tangent; calculating the length of sides of triangles and calculating the...

This RISP activity gives students four properties - one side is 3cm, one angle is 90 degrees, one side is 4cm and one angle is thirty degrees. Students are required to find as many triangles as they can which contain any three of these four properties. Once the triangles have been found, students are asked to find...

The first of two RISP activities, Radians and Degrees, students are set the task of finding an angle whose sine value is the same whether measured in radians or degrees....

Students are required to draw graphs to represent data and critique an incorrect interpretation of the data. Given the results of a survey, students draw a chart or graph of the discrete data provided to help explain why the interpretation of the results provided is incorrect and are required to draw their own...
