Revise
These Subtangent resources are interactive and cover measuring length and angle, rotational symmetry, straight line graphs, linear equations, trigonometry, pie charts and frequency diagrams.
Movies and diagrams are used to demonstrate important concepts in rotational symmetry, straight line graphs and frequency diagrams (which includes stem and leaf).
Random questions are generated in the trigonometry revision activity in the Linear Equations resource which includes an on screen scientific calculator.
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
Measuring
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 protractor are provided in…
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. HEALTH and SAFETY Any use of a resource that includes a practical activity…
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. HEALTH and SAFETY Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed…
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 section which covers interpreting…
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 using frequency polygons…

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 on-screen scientific calculator…
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 and the student is…
