Maths for Key Stage 2: a teacher's guide to making the abstract more concrete.

## What is taught in Maths for Key Stage 2?

The term Key Stage 2 (KS2) is used for a child's second stage of primary education. It encompasses the class years 3, 4, 5 and 6. In KS2, children are generally aged between 7 and 11 years. Key Stage 1 is about building up basic knowledge and skills and introducing subjects to a child and Key Stage 2 develops these skills further and builds on a deeper understanding of the topics. We have provided details of what your child will be studying in Mathematics for Key Stage 2.

In KS2 Maths, children gain much more confidence and accuracy in knowledge of Mathematics: they learn to add, subtract, multiply and divide. Also, they solve problems and do mental maths using money, time, and other mathematical concepts. Disadvantaged pupils might benefit from concrete, pictorial, abstract methods of teaching. More confident pupils might be able to take on the curriculum without any additional scaffolding. Using concrete approaches can certainly help reduce pupil misconceptions and are encouraged to be used in Maths up into key stage 3.

KS2 Students will also start to build connections between what their previous learning and more complicated mathematics such as decimals and fractions. Key mathematical teaching methods you might want to try include:

- Quick-fire practice Maths questions

- SATS-style practice papers

- Edtech programs that 'gameify' the learning experience

## Lower key stage 2 Mathematics – Years 3 and 4

The primary focus of teaching mathematics in primary schools lower key stage 2 is to make children increasingly fluent with the four operations and whole numbers,  including the concept of place value and number facts. At the lower key stage 2  –  years  3  and  4 children develop valuable written and mental mathematics methods and do calculations correctly with increasingly large whole numbers. Children build their ability to solve a wide range of problems, including decimal place values and simple fractions. Children in primary schools should draw with increasing correctness and build mathematical reasoning so they can evaluate shapes with their properties, and correctly demonstrate the relationship between them. Children learn to use measuring instruments correctly and make connections between numbers and measures. Before year 4 ends, children are expected to have memorised their 1 to 12 multiplication tables. Their work needs to demonstrate fluency and precision. Using their increasing knowledge of spelling and word reading, KS2 students must spell and read mathematical vocabulary with accuracy and confidence.

## Upper key stage 2 Mathematics – years 5 and 6

The primary focus of teaching maths in upper key stage 2 is to extend students' understanding of the place value and number system to include larger digits. At this level, students build connections between division and multiplication with percentages, decimals, ratios and fractions. At the Upper key stage 2 level, students build their skills of problem-solving using complex arithmetic and mental methods of calculation. Depending on the arithmetical understanding, students are introduced to the concepts of algebra which to solve a variety of problems. Teaching algebra and geometry extend and consolidate students' conceptual knowledge of numbers. While teaching students, classroom teachers need to make sure that the students categorize shapes with highly complex geometry - properties and geometry - position that they must know the vocabulary they need to define them. By the end of studying upper Key Stage Two Maths in year 6, students must gain fluency in written techniques for all of the four operations, including long division and multiplication, and in using decimals, fractions, and percentages. Pupils must pronounce, read and spell mathematical terminologies correctly.
