Surface area of Triangular based prism
This triangular based prism shown above has a triangle base. The area of this triangular base s ½ bxh and the perimeter of this triangular base is s1, s2, s3. Just add all the...
Surface of Circular based Prism
Here we have a circular based prism; It’s as though the prism has been extruded from the circle below the prism and that’s the general idea behind the prism surface area. The area of...
Surface area of square based pyramid
The following image shows a square based pyramid with labels. Deriving the Surface Area (SA) Let’s try to derive/prove the surface area pyramid above. It’s actually very simple. At the bottom of this pyramid...
Multiplying Decimals
In this chapter we shall be looking at multiplying decimal numbers together. This should be straight forward and simple. Work out 0.6 x 0.8 To work out this easily we’re going to make the...
Pythagoras Theorem
In this section we’re going to be exploring Pythagoras’s theorem. You will understand how to use Pythagoras’s theorem and be able to find the distance between 2 points in a coordinate grid. Pythagoras was...
Prime Factorisation
In this section we shall be looking at prime factorisation. You will be able to understand highest common factors and how to use factor trees to find the highest common factors HCF. What is...
Rounding off decimals
In this section we shall be exploring rounding off decimals. We shall look at rounding decimals off to whole numbers, rounding decimals to certain decimal places and making decisions whether to round up or...
Linear Equations
This is the first entry on equations. In this section we shall be exploring equations at a basic level. This is simply an introduction to linear equations. We shall look at using letters for...
Area of a circle sector
The following image shows a sector in a circle. We can work out the area of a sector by relying on the fraction and percentage of the angle of the sector to the 360o...
