In this activity students are asked to construct a simple mathematical model to help decide whether or not the umpire has made the correct decision. Students are required to revisit and test assumptions made in their initial model, make estimates of likely uncertainty and apply their model to similar situations....

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 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 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 inquiry prompt contains the following mathematical statements:

This resource looks at what properties of infra-red make it so useful in gaming technology? Students develop a working prototype of a simple infra-red electronic circuit, identify an input and an output and test the performance of the circuit. They then explain how the findings of their research could affect their...

Using the context of the Nintendo Wii, this starter activity develops an understanding of the terms system, input, process, output and signal, and asks students to identify these features in some common products which are shown in the presentation.
