This resource contains six activities for use in the classroom when exploring the properties of circles.

The Circle: Contains a variety of questions requiring students to calculate the circumference and the area of circles. Given values for the diameter or radius of the circle. The second...

These 15 instant maths ideas, ideal for use as starter questions, extension question or probing questions to assess understanding, require students to perform a practical experiment in order to estimate a value for pi, describe a circle over the phone, find a connection between the length of the radius of a circle...

This sub-collection of materials from the dy/dan collection contains three resources that bring mathematical storytelling to the classroom in the context of ‘circumference of a circle’. Resources comprise:

• Act One: a video or photograph to provide a ‘hook’ to the problem

• Act Two:...

In this resource from the DfE Standards Unit, students learn to name and classify polygons according to their properties, develop mathematical language to describe the similarities and differences between shapes and develop convincing explanations as to why combinations of particular properties are impossible. (...

These Cre8ate maths activities require the use of averages, ranges, percentages, histograms, stem and leaf displays, pie charts, and tables to make comparisons, interpretations, and conclusions. They also provide real data about pupils for analysis. Performing the “How far can you …?” events in the classroom will...

This collection from Teachers TV features videos, covering a wide range of mathematics topics, which are intended to be shown in class. Often ideal for use as as a lesson starter, some show practical applications of mathematical principles which pose problems for students to solve. Areas covered include:

*...

When you have a set of data the first thing you need to do is to check it out and eliminate any obviously wrong or false data. This is called “Cleaning the Data”.

Science and engineering represent great opportunities for magic. This book contains some amazing and easy-to-do magic tricks based on secret chemistry, physics, engineering and mathematics. The description of each trick explains the effect, how it works and hints and tips for performing the illusion. The illusions...

Because of the shape of the Earth’s orbit around the Sun, it is farther away from the Sun in July than it is in January. Still, we have colder days in January than in July. How is this possible? Through this mystery, students will investigate the orbit of the Earth around the Sun and its influence on solar energy...

In this Nuffield investigation these resources from AMP, co-funded by the Clothworkers and Nuffield Foundation, students investigate how many positive integers are less than and co-prime to any given positive integer. This activity requires some confidence with the co-...

This problem features a coil of tinplate being stored on a mandrel. In the first problem, students are presented with the diameter of the mandrel, the height from the floor, the width of the coil and the density of the steel. The problem is to calculate the maximum coil weight. A worked solution is included with...
