Schemes of Work for Maths Teachers and Schools

Schemes of Work for Maths Teachers As a Head of Maths I understand the importance of a detailed, flexible and simple scheme of work.  I designed the Key Stage 3 and GCSE schemes of work for maths teachers available at to be just that.  They are fully aligned with the current  specifications and are […]

Solving Problems with Non-Right-Angled Triangles

Solving Problems with Non-Right-Angled Triangles Solving problems with non-right-angled triangles involves multiple areas of mathematics ranging from  complex formulae to angles in a triangle and on a straight line. As the GCSE mathematics curriculum increasingly challenges students to solve multiple step problems it is important for students to understand how to prove, apply and link […]

Factorising algebraic expressions with powers

When factorising algebraic expressions with powers students often struggle to identify the highest common factor when it involves an algebraic term. For example, factorising 3h + 12 as 3(h + 4) is attempted correctly much more often than factorising 3h2 + 12h as 3h(h + 4). In this lesson students learn how to identify the […]
