## Year 4 Maths

**These ’I can’ statements are what the children should be able to do at the end of year 4. They are organised into foundation learning (key maths facts) and conceptual learning (key maths concepts). **

Foundational

- I can read and write Roman numerals from 1 to 100 (I to C)
- I can count backwards through zero to include negative numbers
- I can recognise the place value of each digit in a 4-digit number (thousands, hundreds, tens, and ones), round any number to 10, 100 or 1 000 and add multiples of 10, 100 or 1 000 mentally
- I can add multiples of 10, 100 or 1 000 to any number up to 9 999 mentally
- I can use column addition and column subtraction to add and subtract numbers with upto 4-digits
- I can recall and use multiplication and division facts including recognising factor pairs for multiplication tables up to 12 x 12
- I can 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; doubling and halving any number
- I can multiply or divide 2-digit and 3-digit numbers by a 1-digit number using efficient written methods
- I can recognise show and name, using diagrams, families of common equivalent fractions including tenths and hundredths
- I can count up and down in hundredths
- I can recognise and write decimal equivalents of ¼, ½ and ¾, n/10 and n/100
- I can round decimals with one decimal place to the nearest whole number
- I can read, write, compare and order numbers with the same number of decimal places up to two decimal places
- I can compare and classify geometric shapes, including quadrilaterals and triangles based on their properties and sizes
- I can identify acute and obtuse angles and compare and order angles by size up to two right angles
- I can identify lines of symmetry in 2-D shapes presented in different orientations, and complete symmetry diagrams for specific lines of symmetry
- I can recognise and say what is the angle of turn associated with movement between any of the eight compass points
- I can convert between different units of measure for length, mass, capacity and time (including between the 12- and 24-hour clocks)
- I can measure and calculate the perimeter of a rectilinear figure (including squares) in centimetres and metres

Conceptual

- I can identify, represent and estimate numbers using different representations – for example measurement scales
- I can estimate the answer to, and solve, number and practical problems that involve making decisions about applying number facts, place value, rounding and estimation with increasingly large positive numbers
- I can explain how the number system has changed over time to include the concept of zero and place value
- I can solve addition and subtraction two-step problems in contexts, deciding which operations and methods to use and explaining why
- I can estimate the answer to, and solve problems, involving multiplying and adding, including the distributive law and harder multiplication problems such as ‘which n objects are connected to which m objects’
- I can recognise that hundredths arise when dividing an object by a hundred and dividing tenths by ten
- I can solve problems involving increasingly harder fractions to include non-unit fractions where the answer is not a whole number
- I can add and subtract fractions with the same denominator
- I can explain, using place value knowledge, the effect of dividing any number by 10 and 100 on the number and the digits in the number
- I can estimate the answer to, and solve simple measure and money problems involving fractions and decimals to 2 decimal places
- I can interpret and present discrete data using bar charts and continuous data using appropriate graphical methods, including bar charts and time graphs
- I can solve comparison, sum and difference problems using information presented in bar charts, pictograms, tables and simple line graphs
- I can describe positions, and movements between positions, on a 2-D grid, and as coordinates in the first quadrant
- I can describe movements between positions as translations of a given unit to the left/right and up/down
- I can plot specified points and draw sides to complete a given polygon
- I can estimate, calculate, and compare the area of squares, rectangles and related composite shapes using standard units, including centimetre squared (cm2) and metre squared (m2)
- I can solve problems including converting from hours to minutes; minutes to second; years to months; weeks to days
