In May 2015 the United Kingdom went to the polls. A Conservative Government was elected. The UK uses the “first past the post” electoral system. The country is divided into 650 constituencies. The candidate with the most votes from each constituency is elected.
Most other countries in Europe use various forms of proportional representation. This means that the number of MP’s for each party would be proportional to the number of votes that were cast for them. (There are many different forms of PR, but in this exercise, to keep it simple we are going to work out the number of MPs by dividing the vote for each party by the total vote and then multiplying by 650, which is the total number of MP’s in the House of Commons. )
First fill in the missing numbers in this table. You will need a calculator. Remember that to round to two decimal places you need to look at the 3rd decimal place. If this is 5 or more round the 2nd decimal place up. If it is less than 5 then ignore it. eg 34.349239=34.35 to 2dp. 2.983432909=2.98 to 2 dp.
If you got the first exercise correct I want you to illustrate your results with two pie charts. Use this table to work out the degrees for each party. You can draw them in excel or with a protractor and pencil.

If you have not yet tried Squares and Cubes do this first.
A square root is the opposite of squaring a number. The symbol for square root is √.
So if 3²=9 then √9=3
A cube root is the opposite of cubing a number. The symbol for cube root is ³ √.
So if 3³=27 then ³ √27=3
TrySquares, Square Roots, Cubes and Cube Roots to help you become familiar with the important examples of this.

To square a number you multiply it by itself. For example 3² =3×3=9
To cube a number you multiply it by itself three times. So 3³=3x3x3=27
If you are studying GCSE it is very helpful to learn the common squares and cubes to save you time in the non calculator exam. This exercise will help you do that-don’t be tempted to use a calculator! For Functional Skills students you can use a calculator. Look for the x² and x³ buttons on your scientific calculator and use these.
Each time you do this exercise you will get a different selection of questions. To do it again click the refresh icon on your browser.

Here is a dominoes activity to revise sequences and terms. Cut out the dominoes shapes then arrange them so that each question is followed by the answer. If this is hard try this activity first.

A jigsaw to revise linear graphs and their equations. Do you remember y=mx+c? m is the gradient, c is the intercept on the y axis. If you have forgotten this look here first.
Some of these equations need re-arranging so you can find the gradient and intercept, but others are already in the y=mx+c format.
I think this is one of the best jokes yet! Do you get it?

This jigsaw will help you revise simplifying expressions, inequalities, expanding brackets and factorisation. Is this the worst joke yet?

Here is a jigsaw to help practice simplifying surds. This is a Higher GCSE topic. If it is too difficult watch the video first. Hope you like the joke!

Here is a video to help with GCSE revision. The questions come from the second half of a non calculator Foundation paper. These questions were also at the beginning of the Higher paper. They cover important topics you need to be confident with to be sure of getting a Grade C. I strongly recommend you attempt the paper yourself first and then watch the video to see if you got them right and to learn from your mistakes.
