Interactive Maths Resources
Secondary (KS3/4 or K12)
Input: any one of diameter, circumference or area.
Output: the other two (circumference, area or diameter).
Input: radius (circle); height (cylinder).
Output: circumference, area (of circle); volume (of cylinder). Shows the steps of the calculation.
Input: coordinates (x1,y1) (x2,y2).
Output: formula of line, intercept, slope; formula of perpendicular and parallel lines also given.
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.
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 .
Advanced (beyond KS4 or K12)
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)
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 !
TEST YOURSELF: generate your own maze, then try to solve it !
Choose your own spinner colours, then spin them to see what pairs of colours result.
Choose a crab, then bet on it to see if it wins. Gambling is for losers I.
From external sites:
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).
TEST YOURSELF: try to beat the top score !
