These are some basic angles rules and cases. I created these for my year 8 Maths class as many of them were struggling with remembering the various types of angle questions and rules.

I keep talking to lots of classes and also my grandkids about multiplying decimals and I keep seeing the same errors and misunderstandings. Even today I took someone else's year 7 Maths class and very few students could accurately multiply very simple decimals. I have been 'dreaming' about how I could make this video and I am very happy with the end result. By the way, many many older students (and adults) could find this helpful.

Discrete Probability Distributions cause difficulty for many students and this content specifically covers discrete data from a Table of Values and calculating the average or Expected Value. After 40 years of enjoyable and rewarding teaching, I still love and continue to teach. It still amazes me how I continue to still think of better ways of teaching mathematical concepts and I also continue to discover methods of explaining things that help students 'better' understand and become more successful at remembering the concepts. A word of warning from what I have repeatedly seen over the years - most of my videos are placed in a logical or reasonably sequential order and if you watch the first or second video in a playlist and feel comfortable with the concepts, please go to the last video in the playlist to check if you really are okay. Each video in a playlist usually becomes progressively more complex and the 'latter' or 'last' video will often contain common assessment questions where students are known to make errors. I also often include some revision / consolidation / mixture videos in the playlist which I know are crucial to assist with student success in assessments. I hope that you find this very helpful and a blessing in your studies.

This is a second simple example where many students misunderstand and make simple errors. Discrete Probability Distributions are covered in the many countries with Grade 12 students. This content specifically covers discrete data from a Table of Values. After 40 years of enjoyable and rewarding teaching, I still love and continue to teach.

Discrete Probability Distributions are covered in many Grade 12 courses around the world. This content specifically covers discrete data from a Table of Values. So many students struggle with Probability and this is a fairly simple introduction with Discrete Probabilities. You can also find my videos on Youtube under Robert Prestwidge.

This is my second video on Collecting Like Terms with Algebra. I made it this year for my year 8 Math class. I am also on Youtube if you want to see my videos grouped into Topics (playlists) and Years/Grades/Courses.

This is an introduction to the basics of Collecting Like Terms with Algebra. I made it this year for my year 8 Math class. I am also on Youtube if you want to see my videos grouped into Topics (playlists) and Years/Grades/Courses.

My son caught this amazing moment on video. Why did one Chihuahua decide to 'discipline' his brother for continuing to jump over the restraints for trying to temporarily stop him from going into the garage?

This further develops the simple 'tricks' that I have developed over more than 40 years of teaching and fantastic student feedback. You can also find me on Youtube in topics/playlist with much more under Robert Prestwidge.

At the very end of the walk to Delicate Arch, there is this crazy narrow ledge that everyone walks along. I also have a lot of videos on Youtube under Robert Prestwidge, included many Math videos.

My Bella wanted some of my food and made this amazingly cute sound that I'd never heard before. She even did it 3 times after I turned my camera on.

This was made for my year 8 maths class and it goes through some simple examples and a choice of methods and ways to think. Please check me out on Youtube as Robert Prestwidge

Simplifying ratios causes grief to a lot of students. Using the approach in the video, I have seen most students become comfortable with the basics. I also have many videos grouped into topics (playlists) and years/grades on Youtube under Robert Prestwidge.

I further develop in this video some more of the basic understanding that I have found has helped many students cope with Ratios. I also have many videos grouped into topics (playlists) and years/grades on Youtube under Robert Prestwidge.

In this video I go through some basic understanding that I have found has helped many students cope with Ratios. I also have many videos grouped into topics (playlists) and years/grades on Youtube under Robert Prestwidge.

I created this video for and with some of my year 8 students. Trapeziums/trapezoids cause so many problems for students that I created this further video which deals with some of the ways that we can change the appearance of the shape, which causes students to make mistakes in assessments. Sorry about the visuals - I was experimenting with using a data projector, but I still decided to keep the video. I also have playlists (videos in topics) on Youtube under Robert Prestwidge and many other videos.

Kites and Rhombuses both use the same method/formula to calculate their area. I created this video for my year 8 students. I also have playlists (videos in topics) on Youtube under Robert Prestwidge and many other videos.

I created this video for and with some of my year 8 students. So many students struggle with 'remembering' how to get the area of circles. Sorry about the visuals - I was experimenting with using a data projector, but I still decided to keep the video. I also have playlists (videos in topics) on Youtube under Robert Prestwidge and many other videos.

I created this video for and with some of my year 8 students. Trapeziums/trapezoids cause so many problems for students that I created a further video on other cases later on. Sorry about the visuals - I was experimenting with using a data projector, but I still decided to keep the video. I also have playlists (videos in topics) on Youtube under Robert Prestwidge and many other videos.

Some students understand Parallelograms as 'Pushed over Rectangles'. Again, I work on students understanding the basics and help them to memorise the concepts and revise the formulas of the area of a number of shapes. You can also find many more of my videos on Youtube, sorted into topical playlists.

This is my first attempt to make a video with my year 8 class and I also trialled using the information projected onto the whiteboard, which was sometimes washed out, but I think it is still easy to see. This is the first of the Area videos, starting with the Area of a Triangle.

This is part two of my lesson on Transforming Graphs. Many students struggle with transforming graphs. Basically moving them up and down, left and right, reflections and ‘stretching’ them out – called dilations. This is my fun way of talking about it and helping students to better understand and remember the concepts. After 40 years of enjoyable and rewarding teaching, I still love and continue to teach. It still amazes me how I continue to still think of better ways of teaching mathematical concepts and I also continue to discover methods of explaining things that help students 'better' understand and become more successful at remembering the concepts.

Repeated revision and consolidation are so important to student success. This is a brief video in just repeating the basics of the Equation and details of graphing a circle. If they struggle with the Algebra involved with 'Completing the Square' it causes students to doubt their understanding. I have especially produced a separate video on 'Completing the Square' for this purpose. After 40 years of enjoyable and rewarding teaching, I still love and continue to teach.
