Opening up the chapter with Algebra as a focus it seems like a good idea to review the work which has gone on in previous years. This video looks at defining what terms are, coefficients, equations and expressions, factorising and much more. The excitement gets too much!
Two words in the same title which normally strike the fear of spiders in people but worry not! I take the time to go all the way back to Year 6 and show you how fractions are pretty simply really! I add a sprinkle of algebra and out comes another great video for Year 10 students.
This video looks at the excitement which can only be described as adding and subtracting algebraic fractions. Does mathematics get any more exciting than this? Well, I take some time to look at the techniques used to add and subtract fractions using algebra. The key message: make sure you can do it with numbers first!
This video shows what a linear function is and how to solve a whole range of them. Lots of examples are given (even though I can't seem to count above 8!) and discussion around which is the best way to do each example. There can't be much more fun had in Mathematics.
This video reviews the work from Year 9 where we use the gradient/intercepts form and intercept form to sketch straight line graphs. We look at what a relationship is, how to tell if a point lies on a line and how to sketch straight lines, including the "special lines".
This video looks at finding equations of straight lines given certain information. I look at how to find the equation when given the gradient and intercept, two points, and a gradient and one point. There is a practical example at the end which shows how the questions might be structured around the theory.
This video shows how to find the length of a line segment when given two co-ordinates. It then moves on to finding the midpoint of the line segment. It shows an example both forwards and backwards when algebra is thrown into the mix.
This video looks at the link between parallel and perpendicular lines. It helps you identify how to see whether lines are parallel or perpendicular to each other and how to find the equations of lines which might be parallel and perpendicular to each other.
This video looks at solving simultaneous equations using substitution.
Following on from the last video, this looks at the method of solving simultaneous equations by the method of elimination.

These are the videos which are available in each chapter. You will notice that some are free and some are for subscribers only. Making and hosting these videos costs a little bit of money. To help pay for the hosting fees I have no choice but to hide some of the videos and make them for subscribers only.
