Interactive Maths Resources

Secondary (KS3/4 or K12)

Circle Solver

Input: any one of diameter, circumference or area

Output: the other two (circumference, area or diameter).

Circle / Cylinder Calculator

Output: circumference, area (of circle); volume (of cylinder).  Shows the steps of the calculation.

Straight Line Calculator

Input: coordinates (x1,y1) (x2,y2).

Output: formula of line, intercept, slope; formula of perpendicular and parallel lines also given.

Linear Equation Generator

TEST YOURSELF:  try to work out  m  and  c  when given a table of coordinate pairs for  y = mx + c .

Input: the three lengths of a triangle (calculated or measured).

Output: the area of the triangle, one of the angles; also, the area of the circumscribed and inscribed circles.

*Whole numbers - decimals can give unusual results in some browsers.

Teamwork

Input: the times taken by two individuals to complete the job.

Output: the time it would take for them to do it working together (assuming they don't fall out).

Input: a, b, c  for  ax2 + bx + c = 0.

Output: two solutions, or tells you if none exist (imaginary).

Pairs Quiz - practice your factorising skills

TEST YOURSELF:  try to work out  X  and  Y  when given the values of   X + Y  and  X x Y .

Stopwatch

Countdown  Countup  timers

Cubic Equation Solver

Input: real and imaginary coefficients of x3, x2, x and constant.

Output: all solutions, real and imaginary.

*Apologies that some of these don't render the way they should when using Linux / Firefox - we're working on it (popups are part of the problem).

Primary (KS2 or K6)

Fractions Calculator+

Input: any two fractions; add, subtract, multiply or divide them.

Output: the answer (simplified or not) - may give top-heavy fractions (does not calculate mixed numbers).

+ sometimes gives unusual results if the answer should be zero: click OFF the tick, and it works okay - we're trying to sort it properly !

A-maze-ing*

TEST YOURSELF:  generate your own maze, then try to solve it !

Two Spinners*

Choose your own spinner colours, then spin them to see what pairs of colours result.

The Green Crab Always Wins*

Choose a crab, then bet on it to see if it wins. Gambling is for losers I.

Transformations

Excellent Java-based interactive drawing boards for Tessellation, Reflection and Rotation.

Part of the site http://argyll.epsb.ca/jreed/math7/ which has lots of resources (untested by Briteschool).

Draw and Print Simple Shapes

Excellent whiteboard that allows you to print or save as a .gif what you have drawn.

Also, many pages of notes and exercises elsewhere on the above site.

Mathematics Attainment Test
1 hour online revision and tests useful for Key Stage 4 / GCSE revision, with instant feedback.

Revision and tests are randomised, so can be used many times.

Note: give answers in their simplest form (so not 2.6 x 10^3 but 2600, for example).
