Graph Shots

This interactive game from the Association for Science Education (ASE) tackling the interpretation of distance/time graphs in the context of a football match. Graph Shots is an interactive game that develops students' understanding of distance/time graphs. Students compare graphs with written accounts and video...


This Subtangent activity uses information from the Hubble space telescope to emphasise the need for accurate measurements and the costs involved when things go wrong.

There are demonstrations of measuring lengths and angles before asking the students to try for themselves.

An interactive ruler and...

Rotational Symmetry

A simple animation from Subtangent presents examples of rotational symmetry in nature and demonstrates how to establish, using a centre of rotation, the order of rotational symmetry.

Students are given five shapes and invited to investigate their symmetry.

Straight Line Graphs

Straight line graphs from Subtangent demonstrates how to find points from an equation, plot those points and join them to make a linear graph.

Pie Charts

This animation from Subtangent shows students how to read, draw and interpret pie charts as well as highlighting when not to use them.

Students are shown how data, from a frequency table, is converted into a pie chart and clear guidelines for drawing and labelling the charts is given.

There is a...

Frequency Diagrams 1

This activity from Subtangent reviews frequency diagrams and includes examples of histograms, frequency polygons and stem and leaf diagrams.

Thorough descriptions of how to create a grouped frequency table and the details of the construction of the axes for histograms are included.

The advantage of...

Random Trig

This activity from Subtangent generates an endless sequence of trigonometry problems in right angled triangles.

Students can choose to focus on finding a missing side, angle or allow a random selection of questions.

The answers are given and, to support learning, include any necessary working out. An...

Linear Equations

This linear equation calculator from Subtangent allows students to target specific types of equations to solve, ranging from basic questions such as x+5=7 to those which have the unknown on both sides and negative coefficients.

Once a type of equation is selected, the calculator generates a specific equation...

Median and Quartiles

This animation from Subtangent offers a visual representation of median heights.

Students have to order a set of cartoon people according to their height and then use the baseline button, which allows the selection to be checked and the heights read accurately from the vertical axis.

Three arrow heads...

Coins and Dice

This probability simulator from Subtangent allows experiments with coins and dice to be performed quickly.

Students can choose from seven options, including whether to use one coin or two, one or two dice or a combination of both.

The simulation displays the results of the experiments but does not...
