This lesson develops the concept of percentage increase and decrease. In particular students will develop their understanding of:

• Translating between percentages, decimals, and fractions.
• Representing percent increase and decrease as multiplication.
• Recognizing the relationship...

This resource from Susan Wall contains five activities designed to enable students to explore indices both numerically and algebraically. The resource features a number of activities dealing with negative indices and fractional indices.

Starter activities: contains two starter activities. In...

This resource contains two interactive excel files providing an introduction to indices, dealing with products and quotients involving indices and evaluating fractional indices (positive and negative). Each file contains the same further 16 sheets of questions which may...

From the Nuffield Foundation, the purpose of this module is to introduce students to index notation and standard form on the way to the determination of the size of a molecule. It builds up from simple rice-counting and paper-cutting to experiments in chemistry and...

This indices resource contains 21 instant maths ideas covering: basic understanding of powers, statements for which students are required to say whether the statement is sometimes, always or never true, a number of investigations including finding 'happy numbers', the number of squares on a chess board and the...

This MEP resource from CIMT is taken from text book 9A which covers the mathematics scheme of work for the first half of year 9.

Indices and standard form covers: index notation, the laws of indices, negative indices, standard form and fractional indices.

The initial file forms part of the textbook...

This RISP activity from can be used when either consolidating or revising ideas of curve-sketching and indices. The numbers phi, e and pi are used in this investigation where students are asked to estimate the size numbers generated when raising these numbers to different powers. It is suggested that a graphing...

This resource contains ten problems which require students to think, explore and explain the mathematical topic of indices and surds. The problems require students to not only be able to manipulate expressions containing indices and surds but also be able to explain and justify how conclusions are arrived at. A...

Carom Maths provides this resource for teachers and students of A Level mathematics.

This presentation starts with the inequalities associated with triangles and challenges students to develop proofs of the inequalities found in other situations, using the arithmetic, geometric and harmonic means.

The...

This resource from Colin Foster contains nine instant maths ideas containing an activity to assess whether students can use the less than and greater than signs appropriately, an activity using a number line on which to represent inequalities, a number of true or false activities and an exploration of quadratic...

This resource contains two excel programs with interactive spreadsheets dealing with linear inequalities in one or two variables.

This inquiry prompt contains the following mathematical statements:

43 + 21 > 12 + 34

432 + 1 > 123 + 4

Carom Maths provides this resource for teachers and students of A Level mathematics.

This presentation highlights the concept of infinity and its implications, as well as introducing the mathematician Georg Cantor and the arguments relating to infinity that he came up with.

The resource is designed to...
