The third 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 equal and inequality symbols to compare and order decimals and fractions. An ideal use may be for teachers of year 7 to assess prior knowledge and build upon their understanding of ordering decimals and ordering fractions to make comparisons between a mix of decimals and fractions less than one. This lesson follows on from lesson two in this series which can be found in my resources.

Prerequisites (taken from the national curriculum)…

• Read and write decimal numbers as fractions (for example, 0.71 = 71/100)
• Read, write, order and compare numbers with up to 3 decimal places
• Compare and order fractions, including fractions > 1
• Associate a fraction with division and calculate decimal fraction equivalents (for example, 0.375) for a simple fraction (for example, 3/8)
• Identify the value of each digit in numbers given to 3 decimal places
• Recall and use equivalences between simple fractions, decimals and percentages, including in different contexts

.

Lesson criteria…

• Make comparisons between decimals and fractions using equal to or inequality symbols
• Order decimals and fractions using equal to or inequality symbols

NEXT LESSON…
Follow on with the next lesson in this series, ‘Compare and Order Fractions and Decimals > 1’ 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.
