PROGRESSION THROUGH CALCULATIONS FOR DIVISION
Knowing and using number facts
(ongoing)
Using multiplication facts
Year 1 Count on or back in ones, twos, fives and tens and use this knowledge to
derive the multiples of 2, 5 and 10 to the tenth multiple;
Recall the doubles of all numbers to at least 10
Year 2 Derive and recall multiplication facts for the 2, 5 and 10 times-tables and the
related division facts; recognise multiples of 2, 5 and 10;
Derive and recall doubles of all numbers to 20, and the corresponding halves
Year 3 Derive and recall multiplication facts for the 2, 3, 4, 5, 6 and 10 times-tables
and the corresponding division facts;
Recognise multiples of 2, 5 or 10 up to 1000
Year 4 Derive and recall multiplication facts up to 10 10, the corresponding division
facts and multiples of numbers to 10 up to the tenth multiple
Calculate doubles of multiples of 10 and 100 and derive the corresponding
halves
Year 5 Recall quickly multiplication facts up to 10 10 and use them to multiply pairs
of multiples of 10 and 100;
Derive quickly corresponding division facts
Year 6 Use knowledge of place value and multiplication facts to 10 10 to derive
related multiplication and division facts involving decimals (e.g. 0.8 7, 4.8 6)
Using and applying: To support planning, refer to the renewed framework and
curricular targets on using and applying multiplication and division strategies.

YR Related objectives: Count repeated groups of the same size; Share objects into equal
groups and count how many in each group, e.g.
Add trays with small compartments for sorting to the making area. Add collections of
things: bottle tops, sequins, threads, tiny pieces of fabric, etc. Model sharing out the
objects equally. For example: do you all want sequins? I'll put 5 each on your trays. Can you
give everybody the same number of these? Have you got the same?
Page 2 of 13
Hang up 3 bags outside for making collections. Put a number 2 on each bag. Encourage the
children to collect 2 of any treasured object in each bag, for example fir cones or smooth
pebbles. The collections could be used inside and outside in the learning environment for
different purposes, for example as a gallery of natural objects or for adding to the making
area.
Y1 Related objectives: Solve practical problems that involve combining groups of 2, 5 or 10, or
sharing into equal groups
Children will experience equal groups of objects and will count in 2s, 5s and 10s. They will
work on practical problem solving activities involving equal sets or groups,
e.g. If the frog hops in 2s, how many hops will there be
before he lands on 10?
Here are 20 counters. Arrange them in equal rows. Is there
a different way to arrange them in equal rows?
15 children sit at 3 tables. There is the same number of children at each table. How many children sit at each table?
Millie had 6 toffees, she gave half to her friend. How many toffees do they each get?

Related objectives: Represent repeated addition and arrays as multiplication, and sharing
and repeated subtraction (grouping) as division; use practical and informal written methods
and related vocabulary to support multiplication and division, including calculations with
remainders
Use the symbols , -, , and to record and interpret number sentences involving all four
operations; calculate the value of an unknown in a number sentence (e.g. 2 6, 30 - 24)
Children will develop their understanding of multiplication and use jottings to support
calculation:
Sharing equally
Use sharing to answer division questions; Suppose 15
pencils were to be shared out between three children.
How many pencils would each child get? Explain to me
how you could work it out.
Experience divisions that give rise to remainders, such as:
Three friends share 16 marbles equally. How many marbles does each friend get? How many marbles are left over?
Grouping or repeated subtraction
Use practical equipment or objects to answer questions such as: How many 2s make 12?
Relate this to the division 12 2.
Use objects or a number line to support, record or explain this.
For example, starting from 12, jump back in steps of 2, or starting with 12 counters, keep
on taking away 2 counters.
Record this as repeated subtraction and as division:
12 - 2 - 2 - 2 - 2 - 2 - 2 0
12 2 6
12 divided by 2 equals 6
Children explain how they use equipment, objects or a number line to carry out division.
Or count forward, e.g. How many tens make 80?
Page 4 of 13
Repeated subtraction using a number line or bead bar
Show me on a number line how you could do: 12 ÷ 3 = 4
3 3 3 3
The bead bar will help children with interpreting division calculations such as 12 ÷ 3 as ‘how
many 3s make 12?’
Using symbols to stand for unknown numbers to complete equations using inverse
operations
÷ 2 = 4 20 ÷ = 4 ÷ = 4
A number of marbles
divided between 2 groups
gives each group 4 each
20p is divided between some
children. Each child gets 4p.
How many children are
there?
On a number line, I do four
equal jumps. What numbers
could I land on?
Y3
Related objectives: Multiply one-digit and two-digit numbers by 10 or 100, and describe
the effect;
Use practical and informal written methods to multiply and divide two-digit numbers (e.g.
13 3, 50 4); round remainders up or down, depending on the context;
0 1 2 3 4 5 6 7 8 9 10 11 12
Page 5 of 13
Understand that division is the inverse of multiplication and vice versa; use this to derive
and record related multiplication and division number sentences;
Sharing
Children understand division as sharing. They solve problems such as:
42 crayons are divided equally between six pots. How many crayons are there in each pot?
Three children want to buy their grandmother a present costing 1.50. They each give the same amount. How much does each child give?
An 80 cm length of ribbon is cut into four equal pieces. How long is each piece?
Repeated subtraction
Children review multiplication as repeated addition and division as repeated subtraction
by counting hops on a number line. For example, they find how many fours make 24, either
by counting on or back 6 hops of 4.
Children divide a number of objects by using grouping . They understand that one way
to find 30 6 is to find how many sixes there are in 30 . Through practical experience,
they understand that some division calculations have a remainder, for example 13 4 3 R 1:
Grouping ITP may be a useful resource
Children understand the relationship between multiplication and division . For example,
they state two multiplication sentences and two division sentences that relate to a
particular array, for example: Multiarray ITP
5 2 10, 2 5 10
10 2 5, 10 5 2
Page 6 of 13
They use the image of an array to explain why, for example, 2 5 gives
the same answer as 5 2. They also use the image to show how many fives
make 10 and how many twos make 10.
Children should use number lines or bead bars to support their understanding.
0 6 12 18 24
Remainders
Children work out calculations that divide exactly and those that give rise to remainders.
They discuss the images in the ITP 'Remainders'.
Children decide whether to round up or down to answer word problems such as:
We have 21 building block wheels. How many four-wheeled cars can we make?
Peaches come in packs of six. I want 20 peaches. How many packs do I need to buy?
How many 30 cm lengths of ribbon can I cut from a ribbon measuring 2 metres?
Children model such problems with objects or draw a sketch to help them. They discuss
their answers and give reasons why they decided to round up or down.

Related objectives: Multiply and divide numbers to 1000 by 10 and then 100 (whole-
number answers), understanding the effect; relate to scaling up or down
Develop and use written methods to record, support and explain multiplication and division
of two-digit numbers by a one-digit number, including division with remainders (e.g. 15 9,
98 6)
Children will develop their use of repeated subtraction to be able to subtract multiples of
the divisor. Initially, these should be multiples of 10s, 5s, 2s and 1s – numbers with which
the children are more familiar.

Leading to mental division using partitioning
Informal recording in Year 4 for 84 ÷ 7 might be:
In this example, using knowledge of multiples, the 84 is partitioned into 70 (the highest
multiple of 7 that is also a multiple of 10 and less than 84) plus 14 and then each part is
divided separately using the distributive law.
Another way to record is in a grid, with links to the grid method of multiplication.
As the mental method is recorded, ask: ‘How many sevens in seventy?’ and: ‘How many
sevens in fourteen?’
Could also be recorded vertically, for example:
When dividing 64 by 4 children approximate first. They recognise that the answer must lie
between 40 4 10 and 80 4 20, and use this approximation to do a calculation such as:
64 ÷ 4 = 16
40 (4 x 10)
24 (4 x 6)
And similarly for remainders

For 81 ÷ 3, the dividend of 81 is split into 60, the highest multiple of 3 that is also a
multiple 10 and less than 81, to give 60 + 21. Each number is then divided by 3.

The carry digit ‘2’ represents the 2 tens that have been exchanged for 20 ones. In the
first recording above it is written in front of the 1 to show that 21 is to be divided by
3. In second it is written as a superscript.
The 27 written above the line represents the answer: 20 + 7, or 2 tens and 7 ones.

Answer: 32R 4
To find 196 ÷ 6, start by multiplying 6 by 10, 20, 30, … to find that 6 × 30 = 180 and
6 × 40 = 240. The multiples of 180 and 240 trap the number 196. This tells us that the
answer to 196 ÷ 6 is between 30 and 40.
Start the division by first subtracting 180, leaving 16, and then subtracting the largest
possible multiple of 6, which is 12, leaving 4.

Short division of HTU ÷ U
For 291 ÷ 3, because 3 × 90 = 270 and 3 × 100 = 300, we use 270 and split the dividend
of 291 into 270 + 21. Each part is then divided by 3.
291 ÷ 3 = (270 + 21) ÷ 3
= (270 ÷ 3) + (21 ÷ 3)
= 90 + 7
= 97
The short division method is recorded like this:
90 7
3 290 1 3 270 21
This is then shortened to:

The carry digit ‘2’ represents the 2 tens that have been exchanged for 20 ones. In the
first recording above it is written in front of the 1 to show that a total of 21 ones are
to be divided by 3.
The 97 written above the line represents the answer: 90 + 7, or 9 tens and 7 ones.

How many packs of 24 can we make from
560 biscuits? Start by multiplying 24 by
multiples of 10 to get an estimate. As

the answer lies between 20 and 30 packs.
We start by subtracting 480 from 560.

By the end of year 6, children will have a range of calculation methods, mental and
written. Selection will depend upon the numbers involved.
Children should not be made to go onto the next stage if:
1) they are not ready.
2) they are not confident.

Children should always be encouraged to approximate their answers before calculating.
Children should always be encouraged to consider if a mental calculation would be
appropriate before using written methods.
