Maths Year 3
By the end of Year 3 most children should be able to:
Number and Place Value
- count from 0 in 2s, 3s, 4s, 5s, 8s, 10s, 50s and 100s
- 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
- identify, represent and estimate numbers in different ways (objects, money, tallies etc)
- read and write numbers up to 1000 in numerals and in words
- solve number problems and practical problems involving these ideas
Addition and Subtraction
- 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 column addition and subtraction
- estimate the answer to a calculation and use inverse operations to check answers (e.g. using addition to check a subtraction number sentence)
- solve problems, including missing number problems, using number facts, place value, and more complex addition and subtraction.
Multiplication and Division
- recall and use multiplication and division facts for the 2, 3, 4, 5, 8 and 10 times tables
- solve multiplication and division number sentences using the times tables they know using mental methods.
- solve multiplication number sentences, including two-digit numbers multiplied by a one-digit number, using a formal written method.
- solve problems, including those with missing numbers, scaling up and down (e.g. making 3 times bigger), 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 set of objects, including unit fractions and non-unit fractions with small denominators
- recognise and use fractions as numbers, including 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 [for example, 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.
- 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 and hours; 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
Properties of shapes
- draw 2-D shapes and make 3-D shapes using modelling materials; recognise 3-D shapes in different orientations and describe them
- recognise angles as 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.
- interpret and present data using bar charts, pictograms and tables
- solve one-step and two-step questions [for example, ‘How many more?’ and ‘How many fewer?’] using information presented in scaled bar charts and pictograms and tables.
