Maths

At the end of Year 3, children are expected to achieve the following objectives in maths:

 

Number and Place Value

Addition and Subtraction

  • count from 0 in multiples of 4, 8, 50 and 100; find 10 or 100 more or less than a given number
  • recognise the place value of each digit in a three-digit number (hundreds, tens, ones)
  • compare and order numbers up to 1000
  • Know that 10 tens are equivalent to 1 hundred, and that 100 is 10 times the size of 10; apply this to identify and work out how many 10s there are in other three-digit multiples of 10.
  • Secure fluency in addition and subtraction facts that bridge 10 through continued practise.
  • identify, represent and estimate numbers using different representations
  • read and write numbers to at least 1000 in numerals and in words
  • solve number problems and practical problems involving these ideas.
  • add and subtract numbers mentally, including:
  • a three-digit number and ones
  • a three-digit number and tens
  • a three-digit number and hundreds
  • add and subtract numbers with up to three digits, using formal written methods of columnar addition and subtraction
  • estimate the answer to a calculation and use
  • inverse operations to check answers
  • solve problems, including missing number problems, using number facts, place value, and more complex addition and subtraction.

Multiplication and Division

Fractions

  • Divide 100 into 2, 4, 5 and 10 equal parts, and read scales/number lines marked in multiples of 100 with 2, 4, 5 and 10 equal parts.
  • recall and use multiplication and division facts for the 3, 4 and 8 multiplication tables
  • write and calculate mathematical statements for multiplication and division using the multiplication tables that they know, including for two-digit numbers times one-digit numbers, using mental and progressing to formal written methods
  • solve problems, including missing number problems, involving multiplication and division, including positive integer scaling problems and correspondence problems in which n objects are connected to m objects.
  • count up and down in tenths; recognise that tenths arise from dividing an object into 10 equal parts and in dividing one-digit numbers or quantities by 10
  • recognise, find and write fractions of a discrete set of objects: unit fractions and non-unit fractions with small denominators
  • recognise and use fractions as numbers: unit fractions and non-unit fractions with small denominators
  • recognise and show, using diagrams, equivalent fractions with small denominators
  • add and subtract fractions with the same denominator within one whole (e.g. 5/7 + 1/7 = 6/7)
  • compare and order unit fractions, and fractions with the same denominators
  • solve problems that involve all of the above.

Measurement

Geometry: properties of shape

  • measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml)
  • measure the perimeter of simple 2-D shapes
  • add and subtract amounts of money to give change, using both £ and p in practical contexts
  • tell and write the time from an analogue clock, including using Roman numerals from I to XII, and 12-hour and 24-hour clocks
  • estimate and read time with increasing accuracy to the nearest minute; record and compare time in terms of seconds, minutes, hours and o’clock; use vocabulary such as o'clock, a.m./p.m., morning, afternoon, noon and midnight
  • know the number of seconds in a minute and the number of days in each month, year and leap year
  • compare durations of events, [for example to calculate the time taken by particular events or tasks].
  • draw 2-D shapes and make 3-D shapes using modelling materials; recognise 3-D shapes in different orientations; and describe them
  • recognise that angles are a property of shape or a description of a turn
  • identify right angles, recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn; identify whether angles are greater than or less than a right angle
  • identify horizontal and vertical lines and pairs of perpendicular and parallel lines
 

Statistics

 
  • interpret and present data using bar charts, pictograms and tables
  • solve one-step and two-step questions [e.g. ‘How many more?’ and ‘How many fewer?’] using information presented in scaled bar charts and pictograms and tables.
