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. 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.

This activity is based on an original idea in “Thinking Through Mathematics. Strategies for Teaching and Learning. Maths4Life”, published by the National Research and Development Centre.

A letter to the Sheffield Star

Dear Editor

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 yearâ€™s 5.99% rise combined with this yearâ€™s 4.99% rise made a total increase of 10.98%. He has added the percentages, ignoring the fact that this yearâ€™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 donâ€™t understand percentages and APRâ€™s are much more likely to be ripped off. If you need help with maths visit my website at www.mathswithgraham.org.uk where you will find free activities, some with a Sheffield theme such as the Sheaf Valley Maths Trail, to help people of all levels, from the very basic up to Higher GCSE.

Yours faithfully
