The first lesson in the series of: “1. order positive and negative integers, decimals and fractions; use the symbols =, ≠, <, >, ≤, ≥”, taken from the DfE GCSE content and assessment objectives/ Numbers/ Structure and Calculation.

A comprehensive maths mastery lesson introducing KS3 students to the word ‘integer’. This lesson helps students to recognise integers including positive and negative integers and apply this to familiar and unfamiliar contexts. An ideal use may be for teachers of year 7 to assess prior knowledge and build upon their understanding and application of simple arithmetic calculations, negative numbers and greater than and less than (inequality) symbols, alongside the key learning objective (WALT), “Understand the meaning of the word ‘integer’”.

Using principles of teaching for mastery…, this lesson uses the Do It, Twist It, Deepen It structure, to secure, challenge and deepen children’s understanding. Much thought has been given to the question choice and structure of the lesson. Prerequisites are used alongside the Teacher, Together, On My Own structure, to scaffold and model new concepts. Questions are chosen based on small incremental changes to difficulty and to encourage connections.
