The second 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 where KS3 children must apply their understanding of inequality symbols to compare and order positive and negative integers. This lesson helps students to recognise the value of positive and negative integers through use of the number line. 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 and negative numbers or as a follow on lesson from lesson one in this series which can be found in my resources.

Prerequisites (taken from the national curriculum)…

• Read, write, order and compare numbers up to 10 million and determine the value of each digit
• Use negative numbers in context, and calculate intervals across 0
• Understand the meaning of integer and apply it to solve maths problems (not NC)

.

Lesson criteria…

• Apply equality and inequality symbols in contexts involving negative integers
• Appreciate and apply that a negative number with a greater magnitude is less than a negative number of smaller magnitude e.g. -10<-2

.

NEXT LESSON…
Follow on with the next lesson in this series, ‘Compare and Order Fractions and Decimals’ in my resources.

.

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.
