This video is part of the Year 8 series of videos which also covers the module on Real Numbers. Have you every wondered how to find the circumference of a circle? Well, this video is going to show you how to do it. There are a number of worked examples which are fully explained in an easy to understand way. One of my best videos to date!
This is another video in the Year 8 Maths series which also deals with the content area of Real Numbers. In the previous video I looked the circumference of a circle and introduced some key points. Now I'm going to show you how easy it is to find the Area of a circle! One formula. Lots of worked examples. Tips and tricks we use to confuse you. And it's all explained in an easy to understand way.
This is another video in the Year 8 series of Mathematics videos which cover the module of Real Numbers. In the previous video I looked at Areas of whole circles. There were some examples of simple sectors in there too which leads nicely onto this video where I show you how to find the area of any size sector. It's all using one formula. I use lots of examples which are clear and easy to understand.
This video is part of the Using Units of Measurement part of the course and looks at the surface area of a prism. Finding the areas of basic shapes is important (and has been covered in a previous lesson). We can use the information to find the area of all the surfaces of a shape. The easiest shapes to find the surface area of is a prism. So, I take some time to look at what a prism is. There are a number of worked examples which frame the theory which I explain in an easy to understand way.
Imagine making a box and wanting to fill it with chocolate but not knowing how much chocolate to fill it with. This would seem like a pretty large problem to have. Not if you know how to find Volumes of Rectangular Prisms and Cylinders. This video lets me (once again) look at all the things I love in life. Maths, chocolate and ... Jelly Tots!!!! I look at how to find the volumes of prisms and cylinders using lots of different methods. Areas of cross sections are also covered as well as doing Mathematics both forwards and backwards.
Did Pythagoras really come up with his Theorem or did he murder to get it? Such is one of life's mysteries which are discussed in this awesome video! I even do some role play to help get the point across. When I'm not talking about murder (alleged) I am telling you how the rule was discovered and can be used to determine if a triangle has a right angle or not. I ponder how Pyramids were built and about the formula for Pythagoras' Theorem and the wonderful subject of Pythagorean triples and how they can be found. We also look at similar triangles and how they can be used to find Pythagorean Triples. I even do a little bit of Michael Jackson! It really doesn't get much better than this.
Having completed a lesson knowing where Pythagoras' Rule (or Theorem) comes from (and whether it was actually by the man himself or stolen!), we now look at how we can use the Theorem to find the lengths of sides. I start by recapping the theory and then moving onto the idea of how Pythagorean Triples are defined. We look at examples where the sides are whole number lengths and then finish by looking at sides which can be expressed in surds. I know this is the first time that lots of viewers will have met surds and so I look at why writing answers in EXACT FORM (Surds) can be so useful to us. I even take a look at rounding errors. With this knowledge in hand, it's time to look at a couple of examples including where there are questions which are designed to trick us! All in all ... a video I am pretty proud of.
