Use patterns of
last digits when
counting in
multiples.
(see recording)
Count on / back

Derive multiples of
2, 5 & 10
Relate to x facts

Doubles of
numbers to 20
Doubles of
multiples of ten to

Use double facts
Use
multiplication
facts to solve
repeated
addition and
array problems
ie. recognise that
there are 15
sweets because
there are 3
packs with 5 in
each
Count in 2s, 5s
and 10s using
counting sticks,
ITPs, apparatus
Derive / recall 2, 3,
4, 5, 6 and 10 times
tables
Use doubles,
knowledge of
even numbers,
Use knowledge
of multiplication
facts,
Counting in 2s,
3s, 4s, 5s, 6s
and 10s from
any multiple of
the above.
Count on (and
back) in
hundreds from
multiples of one
hundred or any
two digit number.
Solving
multiplication by
partitioning ie. 36
x 3 = 30 x 3 plus
6x3
Use knowledge
of multiplication
facts and place
value ie. 70 x 8 =
560
Counting
forwards and
backwards in
1s, 2s, 3s, 4s,
5s, 6s, 7s, 8s, 9s
and 10s starting
and stopping at
various points
X numbers by

Support with the use of rods, numicon

where necessary. As should the use of
number lines.
Recall quickly facts
to 10 x 10
Use facts to
multiply pairs of
multiples of 10 /

involving multiples
of 10 / 100 (eg
80 x 30) and
decimals (eg 0.8 x

Identify factor pairs
and prime numbers
Derive squares of

Multiply by 4 or 8
by repeated
doubling
Form an
equivalent
calculation e.g to
multiply by 5,
multiply by 10
then halve
Use knowledge
of doubles
Use place value
to solve
multiplication
problems ie. 30 x
40 = 1200
Use knowledge

Use knowledge
of multiplication
facts and factor
pairs
Use knowledge
of multiplication
facts to scale up

three oranges
cost 25p six will
cost 50p, 12 will
cost £1 etc.,
Select the most
