This activity, from the Royal Observatory Greenwich, looks at Hubble’s law, whereby students use real data from the Sloan Digital Sky Survey to plot a graph from which they can obtain the Hubble constant. Students then look at the possible sources of error in their data and use this to calculate the uncertainty in...

The Duston school was one of one of twenty initial Lead Schools for Core Maths, providing support to a network of other schools as they look to deliver mathematics to all post 16 pupils.

Discover more about how Core Maths was delivered by a team of three teachers, working in close collaboration to develop...

This magic trick from the Computer Science for Fun team at QMUL shows that computing is about more than just programming and computational thinking is about more than just algorithms.

A simple mathematical approach is taken with dealt piles of cards – this allows the dealer to control the whereabouts of the...

This unplugged activity from the CS4FN team uses two examples – an insulting computer and one that can play snap – to look at simple computer programming, flow of control and logic. Everything is provided for this front-of-class activity, which would act as an effective starter for a lesson on programming concepts...

In this Core Maths task students are introduced to a new species of jellyfish that has been found off the Sussex coast and nicknamed ‘jellyblubbers’ by local people. It impossible to count how many ‘jellyblubbers’ are present, but some data has been collected and is being analysed for the purpose of answering the...

This RISP activity is ideal for introducing, consolidating or revising the idea of proof using a mathematical argument and appropriate use of logiocal deduction.

Students are asked to choose two triangular numbers and...

This report from Ofsted is based on a survey into the impact in schools of the government’s strategy for continuing professional development (CPD). The strategy was introduced in 2001 and subsequently relaunched in 2005. It aims to promote the benefits of CPD, help teachers make the most of the choices available,...

This resource contains a series of card tricks. Each trick is presented in two parts. In the first part enough detail is given so that the trick can be performed. A description of the desired effect is given followed by an explanation of the mechanics of the trick – actually what is done to ensure the trick works...

The Magic of Computer Science II begins with an introduction to the resource, explaining the basic concepts used in the book. There follows descriptions of how to perform seven tricks with explanations of how the trick works and the computer science concepts illustrated in the tricks.
