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 fifteen years and graded as Outstanding many 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 group work tasks are designed with pace of learning and challenge of thought in mind

Calculating the Volume of a Pyramid

When calculating the volume of a pyramid we can substitute the values of the length, width and perpendicular height into the formula V = 1/3 lwh.  In my experience this is often provided for the students with little explanation as to why a volume of a pyramid is exactly one third the volume of a […]

Solving 3D Problems using Trigonometry

When teaching solving 3D problems using trigonometry we begin the lesson with a recap of Pythagoras’ Theorem and the three trigonometric ratios.  We do this by matching the ratio and equations to the respective right-angled triangle.   Students are encouraged to work in pairs and to show the diagrams as part of the working out on […]

Rounding to a significant figure

When I teach rounding to a significant figure, I ask the class to discuss in pairs or small groups a definition for the word significant.  It is a word that all the students have heard before but not all are able to define. After 2 or 3 minutes of conversation I ask the students to […]
