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

How to Simplify Surds

When learning how to simplify surds students need to understand the difference between a rational and irrational number. Rational numbers include integers and terminating and repeating decimals. They can be written as a fraction with both the numerator and denominator as integers. An irrational number is a number which, in its decimal form does not […]

Sharing an Amount to a Given Ratio

There are three common methods for sharing an amount to a given ratio.  Depending on the age group and ability range I am teaching I would choose one approach over the other two. The three methods are: Using fractions Unitary method Using a table In this blog I will demonstrate each of the three methods […]

Plotting Scatter Graphs and Understanding Correlation

To introduce plotting scatter graphs and understanding correlation I ask students to think about the relationships between different variables and to describe how they might be related. Here’s my starter activity which students discuss in pairs then present to me on mini-whiteboards. When the students have had time to discuss the matching pairs we talk […]
