Calculate mathematical statements for
multiplication and division within the
multiplication tables and write them using
the multiplication (x) and division (&divide;) and
equals (=) signs.
Examples?
Write and calculate
mathematical statements for &divide;
and using the x tables they
know progressing to formal
written methods.
Examples?
Multiply 2-digit and 3digit numbers by a 1digit number using
formal written layout
5 frogs on each lily pad
5 x 3 = 15 (showing multiplication as groups of)

written method,
including long
multiplication for 2- digit
numbers.
Multiply multi-digit
numbers up to 4
digits by a 2- digit
whole number using
the formal written
method of long
multiplication.
Multiplication (x)
With jottings
Or mental
calculations
Examples
Solve one step problems
involving multiplication and
division, by calculating the
objects, pictorial
representations and arrays
with the support of the
teacher.
Show that multiplication of 2 numbers
can be done in any order
(commutative) and division of one
number by another cannot. Solve
problems involving multiplication and
division, using materials, arrays,
and multiplication and division facts,
including problems in contexts.
Write and calculate
mathematical statements
for multiplication and
division using the
multiplication tables that
they know, including for TO
x O, using mental methods.
Use place value,
known and derived
facts to multiply and
divide mentally,
including: multiplying
by 0 and 1; dividing
by 1; multiplying
together 3 numbers.
Mulitply and divide
numbers drawing
mentally drawing
upon known facts.
Perform mental
calculations,
including with
mixed operations
and large
numbers.

To multiply by 25 you
multiply by 100 and
then divide by 4. Use
this strategy to solve
