Maths Workshop for Parents
The question that some parents dread…
Can you help me with my
homework?
Aims of the workshop:
• Understanding how maths is taught at Highfields;
• Making maths interactive – Whiteboards,
Interactive games, times tables CDs;
• Ways in which you can help your child with their
day to day maths;
• Practical opportunities for hands-on maths at
home.

Place Value
What do we mean when we talk about Place Value..?
Simply – recognising that the value of a digit is determined by its
place in a number.

Zero…to hero!
If the answer is 1002, what was the question?
Q: 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 …

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
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.
