About Me

My name is Jonathan Robinson and in Autumn 2012 I launched Mr-mathematics.com with the aim of sharing the teaching and learning resources I use in the classroom every day.

I have been ateacher of Mathematics for over twelve years and graded as Outstanding four times by Ofsted. In 2008 I took on the role of Head of Mathematics at a failing school in the South East. Leading my team with a dedicated focus on teaching and learning the department's results improved from 27% A* to C in GCSE Mathematics when I took on role to 78% four years later.

In September 2013 I was awarded a Masters of Education degree from the Open University specializing in Research in Mathematics Education and Leadership and Management in Education.

Creating pace and challenge in every lesson where every student is fully engaged in understanding mathematical concepts is central to how I teach. As Head of Mathematics and as a Teacher Trainer one of my greatest joys is empowering others to teach their classes so more and more students appreciate the beauty of mathematics. This website is a way for me to continue to do this.

Central to each interactive teaching resource is the premise of Assessment for Learning as a means to encourage teacher and student interactions. In this ever changing and technological world inspiring the young mathematicians of tomorrow has never been more important. Therefore, the lessons, independent learning activities, interactive files and Qwizdom PowerPoint presentations are designed with pace of learning and challenge of thought in mind

Pythagoras Theorem in 3D Shapes

Many problems involve three-dimensional objects or spaces.  Pythagoras Theorem in 3D Shapes can be used as much with these problems as those in plane shapes. Knowing when to use Pythagoras Theorem The starter recaps applying Pythagoras Theorem as part of a larger problem involving the perimeter of a trapezium and square.  The aim of this […]

Drawing Frequency Trees for GCSE Maths

Drawing frequency trees for GCSE maths is a new topic and appears on both the higher and foundation curriculum.  I’ve taught this lesson a couple of times, once to Year 10 and once to Year 11 and I have to say the kids really enjoy it. What is a frequency tree? Frequency trees can be […]

How to calculate speed using ratio notation

Whenever I teach how to calculate speed as a measure of distance and time I either use the formula or the triangle method.  In my experience most students are know about the triangle method from their science lessons.  For this reason I would have expected speed to appear either within the algebra or shape and measures strands of […]
