This resource, from the Maths Careers website, contains a quiz in which teams have to solve a different type of code of cypher in each round.

The topics covered include mobile texting, transposition of messages, pencil code, binary and frequency analysis.

The activity was written in conjunction with...

This activity from Cre8ate maths explores the rotational symmetry of carefully chosen crystals. Initially students work with plain and coloured nets of cubes may use trial and improvement methods to find different possible rotations of symmetry, before exploring ways to be systematic in their investigation. For...

This activity from Cre8ate maths explores Platonic solids, which are formed from regular polygons where all their faces are identical and all their vertices are identical too. Students are told that there are only five platonic solids, which they can build using triangles, squares and pentagons. Completing the...

In this activity, students learn about X-ray crystallography. As well as considering its importance (scientists have used the technique to elucidate the structures of over half a million substances) students use models to learn about – and...

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop the idea that substances in the solid state usually consist of crystals, even though...

This resource, from the Maths Careers website, contains data collected from 100 groups competing in a cube puzzle.

The information was collected as part of the Big Bang London Science Fair and includes a range of investigations to help explore the data. Areas covered include scatter diagrams, correlation,...

In this teacher presentation and collection of student worksheets, the area of each face of a cuboid is given. Students are then asked to calculate the volume.

Each student worksheet contains a different cuboid, but the solutions all have something in common. The teacher presentations highlights two possible...

Each student worksheet contains a different cuboid, but the solutions all have something in common. The teacher presentations highlights two possible...

This interactive excel file begins with a sheet showing the dimensions of a cuboid beside an oblique drawing of the cuboid. The student needs to calculate the area of the three different faces, the total surface area and the volume of the cuboid. The dimensions can be...

This activity is from the Association of Teachers of Mathematics (ATM) publication ‘Learning and Teaching Without a...

This role play activity illustrates natural selection, based on the cuckoo/host example of co-evolution. as well as providing opportunities for developing key scientific skills such as experimental design and research.

Examples of natural selection and evolution in secondary...

This podcast from the Natural Environment Research Council's (NERC) Planet Earth Online collection looks at the cunning tricks the cuckoo uses to get another bird to do the parenting, why researchers are studying snow in Sweden, and discovers an improved radiocarbon dating technique.

The cuckoo is a well-...

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.

Cumulative frequency covers: a recap of the three types of average, a recap of range, how to graph grouped data, how to find the average of grouped data, culmulative frequency,...

This resource is an introduction to conversion graphs and direct proportionality in the context of currency conversion, reading and plotting graphs and calculating gradients, including using a spreadsheet.

The resource is part of the Nuffield Maths Level 1 Foundation resource collection.
