**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** (x_{1},y_{1})
(x_{2},y_{2}).

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
ax^{2} + bx + c = 0.

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

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 x^{3}, x^{2}, 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 !
