Subtangent
Subtangent is a website of free interactive mathematics resources. This collection includes interactive investigations, games activities to test mathematical knowledge and resources for printing.
The majority of the resources are suitable for Key Stages Two to Four. Some would be useful as whole class introductions or demonstrations on an interactive whiteboard.
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.
Investigations
These interactive investigations from Subtangent help to develop a systematic approach but require students to use their own recording methods. They can be used as a whole class introduction to an investigation or as individual tasks. There are additional resources with some of the investigations so that pupils can either work…
Games
This collection of games from Subtangent is suitable for students from Key Stage Two to Four. It includes mathematical variations on many classic games and activities. Transformation Golf, Maths Hangman, Mathionaire, Countdown and Broken Calculator are some of the games available in this resource, covering a wide range of topics…
Test Yourself
These Subtangent resources use an interactive format to set 10 questions on topics such as properties of number, Pythagoras theorem, quadratic equations and function machines. Each of the activities contains 10 questions which increase in difficulty as the test progresses. Once completed students can check their answers and identify…
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…
Simulations
These Subtangent resources contain a standard form calculator which will quickly change ordinary numbers into standard form and vice versa. There is also a simulation for probability outcomes involving coins and dice, as well as an interactive animation to demonstrate placement of the median and quartiles of a distribution.
Resources
Subtangent's resources for mathematics include different types of isometric grids which can be printed, a set of lesson starter activities, a variety of worksheets to practice arithmetic skills and graph paper with axes and different quadrants labelled, all of which can be printed freely. The lesson starters contain 30 challenges,…
