Numeracy in Years 3 and 4

Year 3 numeracy 

Key objectives to be achieved

Ø      Read, write and order whole numbers to at least a 1000; know what each digit represents

Ø      Count on or back in tens or hundreds from any two-or three digit number e.g. count back from 156 in 10s

Ø      Recognise unit fractions such as ½, 1/3, ¼, 1/5, 1/10, and use them to find factions of shapes and numbers e.g. 1/3 of 6=2

Ø      Know by heart all subtraction and addition facts for each number to 20 e.g. 14+6=20, 6+14=20, 20-6=14, 20-14=6

Ø      Add and subtract mentally a near multiple of ten to or from a two-digit number e.g. +19 by adding 20 then subtracting 1

Ø      Know by heart facts for the 2, 5, 20 multiplication tables

Ø      Understand division and recognise that division is the inverse of multiplication e.g. There are 19 books on the top shelf and 32 books on the bottom shelf. 24 of the books are removed. How many books are left?

Ø      Identify right angles, 90 degrees, quarter of a turn

Ø      Identify lines of symmetry in simple shapes and recognise shapes with no lines of symmetry

Ø      Solve a given problem by organising and interpreting numerical data in simple lists, tables and graphs e.g. solve a problem such as: What is our favourite sport? Respond to questions such as; How can we find out? What information should we collect, and how shall we organise it?

Year 4 numeracy 

Key objectives to be achieved

Ø      Use symbols correctly, including less than <, greater than >, and equals =

Ø      Round any positive integer (whole number) less than 1000 to the nearest 10 or 100

Ø      Recognise simple fractions that are several parts of a whole e.g. 1/4, and mixed numbers e.g. 5 ¾; recognise the equivalence of simple fractions e.g. 4/8 equals 2/4

Ø      Use known facts and place value to add or subtract mentally, including any pair of two-digit whole numbers e.g. 27+64

Ø      Carry out column addition and subtraction of two integers less than 1000, and column addition of more than two such digits e.g. 625

            48

          +57

Ø      Know by heart facts for the 2, 3, 4, 5 and 10 multiplication tables and quickly work out division facts

Ø      Find remainders after division

Ø      Know and use the relationships between familiar units of length, mass and capacity e.g.

Ø      1 kilometre = 1000 metres

Ø      1 metre = 100 centimetres

Ø      1 centimetre = 10 millimetres

Ø      1 litre = 1000 millilitres

Ø      Classify polygons (2-D shapes), using criteria such as number of right angles, whether or not they are regular (all sides the same length), symmetry properties

Ø      Choose and use appropriate number operations and ways of calculating (mental, mental with jottings, pencil and paper) to solve problems
