How we support Maths in school
Making maths interactive – Whiteboards,
Interactive games, times tables CDs
Place Value
What do we mean when we talk about Place Value..?
Simply – recognizing that the value of a digit is determined by its place
in a number.

. Tenths

Hundredths
Zero…to hero!
If the answer is 1002, what was the
question?
Qu: Write the number one hundred and two
in digits...
Children need to understand that in
102, there is one lot of one
hundred, zero lots of ten and two
units. Zero ‘holds’ the place of the
tens.
Common mistakes…
• Writing ‘one hundred and thirty six’ as
10036.
• Thinking that 6,000 is one more than
5099.
• Thinking that 3.153 must be larger than
3.35 because it has more digits in it.
• Thinking that 0.75 is smaller than 0.203
because 75 is smaller than 203.
Partitioning
What does the word mean..?
Breaking a number up according to its place value.
(typically to make addition and multiplication easier).
3276
3000+200+70+6
So 52 x 3 becomes
50+50+50 and 2+2+2 …

Q. I have 28 apples in one hand and 57
apples in the other. What have I got..?

Mental Warm-up 3
Q. Sam has £1 in his pocket and apples cost 30p each. How many
apples can Sam buy? Show how you got your answer.
Times tables
• Finally! Some old fashioned Maths
teaching!
• Nothing has changed... Children need to
learn their times tables.
• Without their times tables they may know
the method for multiplication, but still arrive
at a wrong answer.
• Rote learning
Mental warm-up 4
Qu. One of these numbers below is a
multiple of 5.
Put a ring around it.

Division
• Bus stop method
Division - Chunking
• 1311 ÷ 23 =
Everyday ways to improve your
child’s (and your!) maths
• A prominent clock in the kitchen – ideally analogue and digital.
• Display a traditional calendar.
• Board games that involve dice and spinners – helps not only with
counting but with the concepts of chance.
• Traditional playing cards – simple games such as snap are a natural
way of learning about sorting and chance.
• Dominoes – to help with number combinations.
• A calculator.
• Measuring jugs with scales / kitchen scales.
• Dried pasta…or Smarties! – useful for counting large collections to
investigate remainders etc.
• Tape measure and ruler – involve your child in ‘real life’ situations.
• An indoor / outdoor thermometer.
