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.
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.
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…
Quadratics 1
This Subtangent test progresses from students identifying quadratic expressions, expanding brackets and factorising expressions to solving quadratic equations. Students are given four possible answers to choose from and there is an opportunity to review their choices before submitting their final answers. An explanation of…
Pythagoras' Theorem
This Subtangent test on Pythagoras' theorem gives students the opportunity to practice all aspects of this topic. Questions begin with simple calculations and progress to problems which are set in context as well as a complex 3-dimensional application. An on screen calculator with root, square and memory keys, is available. Students…
Properties of Numbers
In this Subtangent resource there are 10 questions of increasing difficulty starting with factors and multiples. Square and triangular numbers LCMs and HCFs complete the topics. Students are given four possible answers to choose from and a calculator is available for some of the questions. There is an opportunity for students…

Hexagons
Matching numbers in hexagons is the challenge in this Subtangent activity. Seven hexagons each with six numbers have to be placed on a grid so that the numbers match. The hexagons can be moved and rotated. Placing the central hexagon is the key to solving this puzzle and a hint is available to help to choose the correct one.…
Matching Game
Matching names of shapes to their drawings is the focus of this interactive game from Subtangent. Students need to remember the position of cards which have already been revealed to complete the task as quickly as possible. This game gives an opportunity to reinforce knowledge of the properties of shapes.
Broken Calculator
Is it possible to use the broken calculator in this Subtangent activity to make a given set of numbers? There are six levels of difficulty in this activity starting with whole numbers, then introducing negative numbers and decimals. The broken keys vary at each level giving the opportunity to use the memory function and power…
Decanting Puzzle
Students are challenged to measure a set quantity of liquid in this activity from Subtangent, using two jugs of different capacity.
