This is one in a large series of short videos from NCETM showing how people use maths at work. See the others here.

When you have watched the video see if you can convert time into decimals and work out how much employees should be paid.

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.

If you can factorise a quadratic that is the easiest way to solve it. Some quadratics don’t factorise, so then we can use the formula. This video from jayates shows how to do it. If you are studying GCSE Higher you are currently given the formula in the exam so you don’t have to learn it off by heart, but don’t forget to refer to the formula sheet at the front of your exam paper when you need it.

 

Maths is fun explains this well but don’t worry too much about the “imaginary numbers” at the end. If you are doing Higher you don’t need to know that yet.

Here is a worksheet that you can print off and practice solving quadratics with the formula.
