This video from Aljazeera explains the origins of Algebra and how important it is for us today.
When you’ve watched the video try these questions.
Here is a complete lesson with 18 activities and some exam questions at the end to see if you have understood.
Drag the numbers to the right place in the Venn Diagram.
Drag the numbers to the right place in the Venn Diagram. If the number is in both sets, make sure to place it in the intersection, where the sets overlap. If the number is not in either set, place it in the box at the bottom.
Drag each statement to the correct box.

A very common mistake in maths exams is to forget to label the axes of a graph. Here are 10 graphs without labels on the y axis. Can you use your skill and judjement to work out what they should be? Click on the graph to enlarge it.

For those of you revising for Paper 2 and 3 GCSE Maths then this site is a must. You will find predicted papers that have been carefully written considering what topics have already been tested in Paper 1. You get immediate feedback on your answers and can see what grade you would potentially get if you do the same in the real exam. If you get stuck there are video explanations of each question. A great way to revise.

A letter to the Sheffield Star
As someone who teaches maths for a living it saddens me when I see mathematical errors in your paper.
In a letter about Council Tax increases (21.2.18) Ron Sanderson claimed that last year’s 5.99% rise combined with this year’s 4.99% rise made a total increase of 10.98%. He has added the percentages, ignoring the fact that this year’s increase is 4.99% more than the new total for last year.
For every 100p you paid in Council Tax in 2016, you paid 100 x 1.0599 in 2017.
In 2018 you will pay 100 x 1.0599 x 1.0499 which equals 111.28p or an increase of 11.28%
Understanding percentages is vital when working out things like Council Tax rises, pay claims, credit agreements or interest earnt on investments. People who don’t understand percentages and APR’s are much more likely to be ripped off.
