Year 4

Year 4 is a vital year in your child's mathematical development. Concepts learnt here form the basis of algebra, the ability to manipulate fractions and decimals and more advanced calculations. Key areas for the year are:

  • fluency in mental and written calculations, including multiplication and division

  • all multiplication tables to 12 x 12 taught and required to be learnt by the end of the year

  • decimals are linked to fractions and included in calculations

  • place value knowledge progresses to include decimals and negative numbers

  • converting between units of metric measures

  • knowing the names and properties of common 2-D shapes

Below are the expectations of the Walhampton mathematics curriculum for Year 4. These form the basis of the 'expected' attainment grade. It is expected that some children will be able to exceed these objectives and explore the topics in more depth.


Number and Place Value Skills

Children will learn to:

  • identify, represent and estimate numbers using different representations

  • read Roman numerals to 100 (I to C) and know that, over time, the numeral system changed to include the concept of zero and place value

  • round any number to the nearest 10, 100 or 1000

  • solve number and practical problems that involve all of the above and with increasingly large positive numbers.

Calculation

Children will learn to:

  • count in multiples of 6, 7, 9, 25 and 1000

  • count backwards through zero to include negative numbers

  • estimate the answer to a calculation and use inverse operations to check answers

  • add and subtract numbers with up to 4 digits using the formal written methods of columnar addition and subtraction, where appropriate

  • solve addition and subtraction two-step problems in contexts, deciding which operations and methods to use and why

  • recall multiplication and division facts for multiplication tables up to 12 x 12

  • use place value, known and derived facts to multiply and divide mentally, including:

    • multiplying by 0 and 1

    • dividing by 1

    • multiplying together three numbers

  • recognise and use factor pairs and commutativity in mental calculations

  • multiply two-digit and three-digit numbers by a one-digit number using formal written layout

  • solve problems involving multiplying and adding, including using the distrubutive law to multiply two-digit numbers by one digit, integer scaling problems and harder correspondence problems such as n objects are connected to m objects

Fractions and decimals

Children will learn to:

  • count up and down in hundredths; recognise that hundredths arise from dividing an object by one hundred and dividing tenths by ten

  • recognise and show, using diagrams, families of common equivalent fractions

  • add and subtract fractions with the same denominator

  • solve problems involving increasingly harder fractions to calculate quantities, and fractions to divide quantities, including non-unit fractions where the answer is a whole number

  • recognise and write decimal equivalents of any number of tenths or hundredths

  • recognise and write decimal equivalents to one-quarter, one-half and three-quarters

  • round decimals with one decimal place to the nearest whole number

  • compare numbers with the same number of decimal places up to two decimal places

  • find the effect of dividing a one- or two-digit number by 10 and 100, identifying the value of the digits in the answer as ones, tenths and hundredths

  • solve simple measure and money problems involving fractions and decimals to two decimal places

Algebra

Children will learn to:

  • solve problems involving missing number problems.

Measurement

Children will learn to:

  • convert between different units of measure

  • estimate, compare and calculate different measures including money in pounds and pence

  • read, write and convert time between analogue and digital 12- and 24-hour clocks

  • solve problems involving converting from:

    • hours to minutes

    • minutes to seconds

    • years to months

    • weeks to days

  • measure and calculate the perimter of a rectilinear figure in centimetres and metres

  • find the area of rectilinear shapes by counting squares

Geometry

Children will learn to:

  • compare and classify geometric shapes, including quadrilaterals and triangles, based on their properties and sizes

  • identify lines of symmetry in 2-D shapes presented in different orientations

  • identify acute and obtuse angles and compare and order angles up to two right angles by size

  • identify lines of symmetry in 2-D shapes presented in different orientations

  • complete a simple symmetric figure with respet to a specific line of symmetry

  • describe positions on a 2-D grid as coordinates in the first quadrant

  • describe movements between positions as translations of a given unit to the left/right and up/down

  • plot specified points and draw sides to complete a given polygon

Statistics

Children will learn to:

  • interpret and present discrete and continuous data using appropriate graphical methods, including bar charts and time graphs

  • solve comparison, sum and difference problems using information presented in bar charts, pictograms, tables and other graphs.
