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

Solving Problems with Angles in Parallel Lines

Solving problems with angles in parallel lines is like solving a murder mystery.  One clue leads on to the next and the next until the murderer is found.  However, it doesn’t end there.  The detectives need to explain their reasoning in court using the relevant laws and procedures should the murderer plead not guilty.  If […]

Solving Two Step Equations using the Balance Method

An equation is when one expression, or term, is equal to another.  To solve an equation means to find the value of the variable (represented by a letter) that makes the two expressions equal.  There are two types of equations for secondary school mathematics, linear and none-linear.  In this blog I write about how I […]

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 […]
