Mathematics Year 5 – Number skills and concepts to keep practising
It is not about achieving each thing once, but regular practise –So that it becomes learnt and is retained for the long term.
Being confident at and able to explain these skills is a good starting point for achieving at year 5.
If you have any questions or would like further explanation please come into school and speak to your child’s class teacher.
1.
Read, write, order & compare numbers to at least 1 000 000 and determine the value of each digit.
7,546,209 – ‘The value of the 5 is 500,000’
‘The value of the 9 is 9’
‘The value of the 6 is 6000’
2.
Count forwards or backwards in steps of powers of 10 (10/100/1000) for any given number up to 1 000 000. Round any number up to 1 000 000 to
the nearest 10, 100, 1000, 10 000 and 100 000
E.g. adding 100
345,657 – 345,757 – 345,857 – 345,957 – 346,057
(Include crossing barriers – the next 100 or 1000)
E.g. Round to the nearest 100: 342,675 becomes 342,700
3.
Multiply and divide whole numbers and those involving decimals by 10, 100 and 1000. (Move up or down in place value)

4.
Add and subtract whole numbers with more than 4 digits, including using formal written methods (columnar addition and subtraction).
72638 + 28543
65421 - 23884
5.
Multiply numbers up to 4 digits by a 1- or 2-digit number using a formal written method. Divide numbers up to 4 digits by a 1-digit number using
the formal written method of short division.
3628 x 4
2435 x 36
4000 ÷ 6
6.
Identify, name and write equivalent fractions of a given fraction, represented visually, including tenths and hundredths.
7.
Compare and order fractions whose denominators are all multiples of the same number. Add and subtract fractions with the same denominator
and multiples of the same number.
8.
Recognise mixed numbers and improper fractions and convert from one form to the other and write mathematical statements > 1 as a mixed number.
9.
Multiply proper fractions and mixed numbers by whole numbers, supported by materials and diagrams.
10.
Round decimals with two decimal places to the nearest whole number and to one decimal place. Read and write decimal numbers as fractions (e.g. 0.72 = ⁷²∕₁₀₀).
e.g.
Round to the nearest whole number:
Round to the nearest one decimal place:
4.56 becomes 5
4.56 becomes 4.6
11. Read, write, order and compare numbers with up to three decimal places
