This resource from Jonny Griffiths contains a range of puzzles designed for 14 to 17 year old maths students. In each puzzle, the digits one to six have been rubbed out and replaced with six squares labelled a to f. The task is to put the digits back in again correctly to make each statement true...

Dijkstra's algorithm finds the shortest path for a given problem. Dijkstra's algorithm can be used to find the shortest route between two cities. This algorithm is so powerful that it not only finds the shortest path from a chosen source to a given destination, it also finds all of the shortest paths from the...

This resource contains eight instant maths ideas designed to provide the opportunity for students to explore conversion graphs, compare imperial and metric units, estimate everyday measurements and explore the nature of different dimensions. The student resource sheet requires students to convert between different...

Published by the ARKive Project, this fun and interactive game explores food chains in a marine environment, predator-prey relationships and the fine balance of an ecosystem. The resources include teachers notes and students activity sheets.

Please note that the ARKive.org website is no longer available...

This Barefoot Computing animation project for primary school computing teaches the concept of sequencing within programs. Children use costumes and a range of commands in Scratch to produce purposeful multimedia. They are encouraged to debug and improve the program, and...

This interactive excel file has separate sheets which deal with direct proportion where the functions are linear, quadratic, cubic and square root.

Each sheet begins with a statement of the proportional relationship,...

This SMILE resource contains one pack of games, investigations, worksheets and practical activities supporting the teaching and learning of directed numbers, from reading directed numbers from a scale to multiplying and dividing directed numbers.

Directed Numbers contains eleven work cards...

In this activity, students develop a marketing strategy and advertising materials for a pure water product. Students mirror the design process within a ‘design consultancy’ and each team makes a pitch for the tender at the end of the project, presenting ideas to the...

This Study Plus unit from the National Strategies asks students to plan the relief aid for a fictitious tsunami along the South American Pacific coast. The project is centred on Concepción, Chile’s second largest urban conurbation. This was the scene of an actual tsunami in 1960, after an earthquake off the Chilean...

This suite of student activities, challenges and related resources aims to give students an insight into the roles of engineers following a natural disaster.

The short introductory activities increase students’ awareness of the range of types of natural disaster and the kinds of problems associated with them...

The aim of this resource is to give students the opportunity to investigate the RAF use science, technology, engineering and mathematics skills when delivering humanitarian aid. Students will design and make a lander for aid delivered by aircraft.

Welsh versions of the guidance documents are included.

In this activity, students are given a Venn diagram and asked to find eight different probability distributions, one for each of the eight regions in the Venn diagram. The notes give solutions for the regions that are possible.

This resource is part of the Making Stats Vital collection from Jonny Griffiths...

This exercise is designed to ensure that students know how to find the expected value, E(X), and the variance, Var(X) for a discrete random variable, and that the probabilities in a probability distribution always add to one. Students are given a selection of numbers and are challenged to establish those...

In this activity students examine how rolling a dice and doubling the score produces a different probability distribution from rolling two dice and adding the scores on the two die. This activity can be conducted experimentally, with the simulation on sheet two of the spreadsheet producing many trials with...

In this activity students are asked to investigate whether it is possible for a four-sided dice, with positive integer faces including odd numbers, to ever have expectation and variance the same. Sheet two carries a simulation with sheet three providing a search programme to find all possible solutions.
