Maths overview

At Derwentwater, our maths curriculum has been designed with the intention of developing fluency, reasoning and problem-solving skills in every child. We have adopted a Maths Mastery Approach to teaching mathematics. At the centre of this approach is the belief that all children have the potential to succeed and develop a positive attitude towards maths.

All children have access to the same curriculum content and opportunities to master the concept being taught through small coherent steps based on previous learning. Teachers differentiate through levels of support rather than different tasks.

Key Stage 1

In Key Stage 1 students explore numbers up to 100 and beyond. Students count forwards and backwards in ones, multiples and using their knowledge of place value begin to compare numbers.

By the end of Year 2, students should know their number bonds to 20 and be able to recall these facts when solving increasingly challenging addition and subtraction problems.

Using various concrete resources, pictorial representations and skip counting students begin to learn their multiplication and division facts.

Students begin to find fractions of objects, shapes or basic quantities. In Year 1 students learn about halves and quarters. This is extended in Year 2 when students learn about thirds.

In Year 1, students begin to learn about comparing units of measurements through using mathematical vocabulary such as: longer/shorter, heavier/lighter. In Year 2, students are expected to recognise formal units of measurement and use these when estimating and measuring. Students are taught about money and are expected to combine different coins and notes.

Students should be able to recognise and name 2D and 3D shapes. In Year 2, students are expected to describe shapes using properties such as lines of symmetry and edges.

Students are formally assessed at the end of each term using White Rose Hub End of Term Assessments, Teachers also use White Rose Hub End of Block Assessments throughout the term.

Key STage 2

In Key Stage 2 students explore the place value of numbers beginning with three digit numbers and gradually progress to numbers over one million. Students round numbers to various powers of ten and count forwards and backwards in multiples of 10. Negative numbers are explored and by the end of Year 6 students complete calculations with negative numbers.

Students use concrete materials, pictorial representations and formal methods to develop their understanding of the four operations. By the end of Key Stage 2, students calculate using four-digit numbers of beyond and apply these skills to problems involving inverse operation, estimation and multi-step word problems. In Year 4, students embed  all multiplication and division facts. In Year 5 and 6, students learn about multiples, factors, prime numbers, squared and cubed numbers.

In Year 3 and 4, students count forwards and backwards in fractions, find fractions of amounts and add and subtract fractions with the same denominators. This is extended in Year 5 and 6 when students compare fractions, convert between improper and improper fractions and calculate with fractions with different denominators.  By the end of Key Stage 2,  students recognise  equivalent fractions, decimals and percentages.

Using various units of measurement, students compare, calculate and convert between different units of measurement.  Students calculate the perimeter and areas of various 2D shapes. In Year 3 and 4, students explore time further, learning about 24-hour time, duration of events and converting between units of time.

Students are able to classify 2D and 3D shapes based on their properties. Using the properties of 2D shapes, students make deductions about missing sides and angles. Students use protractors to measure and draw angles. Using grid coordinates, students translate and reflect 2D shapes.

Students solve comparison, sum and difference problems using data presented in various graphs and tables.
