Here are the key things that we looked at...

__**30th May**__ SHAPE([])
 * 3D shapes, nets, area, volume**

Key words - Faces, edges, vertices (corners)

A //prism// is a solid shape with the same 'cross section' all the way through it. A //pyramid// has a flat base with an edge from each vertex meeting at a 'top' vertex

A //net// is a flat representation of a 3D shape, formed by cutting along some edges and 'flattening out' the shape

A //cuboid// is a 'rectangular prism' A //cylinder// is a circular prism

We also looked at triangular prisms and square based pyramids.

The area of a shape is the number of squares (often square centimetres) that fit inside the shape.
 * AREA**

The area of a rectangle is always width x length The area of a triangle is always base x perpendicular height ÷ 2

To calculate the //surface area// of a solid shape we need to add together the area of all the faces. This can be a lot easier if you have a net.

The volume of a shape is how many cubes (often cubic centimetres) that fit inside the shape.
 * VOLUME**

The volume of a cuboid is always length x width x height


 * __AVERAGES__**
 * (**[])
 * It's always a good idea to put numerical data in order**

MODE - the piece of data that occurs the most. If all the data is different then there is NO mode. You can have more than one mode... The adjective for 'mode' is MODAL

MEDIAN - the middle piece of data WHEN IT HAS BEEN ORDERED!! If there is an odd number of pieces of data there will be ONE number in the middle (easy!) If there is an even number of pieces of data there will be TWO numbers in the middle - the median is half way between them. (you can find this 'midpoint' by adding the two numbers and then dividing by 2)

MEAN - add the numbers together (write down the sum) then divide by how many there are.
