# Visualisation in Mathematics Aims

```Visualisation in Mathematics
Aims
• To reflect on current practice in providing
opportunities for developing visualisation
• To engage in a number of activities that
involve visualisation and reflect on the key
skills and attitudes involved
• To explore ways that visualisation can be
incorporated into classroom practice
• To consider resources that might be useful
Warm up!
Describe a route from Calcot to
Birch End.
A Powerful Force
‘Imagery is a powerful force for perception
and understanding. Being able to “see”
something mentally is a common
metaphor for understanding it. An image
may be of some geometrical shape, or of a
graph or diagram, or it may be some set of
symbols or some procedure.’
Open University
Current Practice
• Consider the visualisation opportunities
you offer your children in your
mathematics lessons.
Activity
• Numbers –
Eight, five, four, nine, one, seven, six, ten,
three, two
• Months –
April, August, December, February, January,
July, June, March, May, November, October,
September

Nets
What shape does this net make?
Which face is opposite GHJK?
Which edge meets IL?
Which points meet at A?

100 square
100 square
• A hundred square has been printed on
both sides of a piece of paper. One square
is directly behind the other.
• What is on the back of 100? 58? 23? 19?
• Can you see a pattern?
Time to Imagine....
• Imagine a clock with hands, on the wall
in front of you.
• The long hand is pointing to 4. The short
hand is pointing between 11 and 12.
• What time is it?
• Now imagine the clock is behind you
and you can see it in the mirror.
• The hands look as though they are
saying twenty-five to three.
• What time is it really?
• Now imagine a digital clock behind you.
In the mirror, it looks as though the time
is 10:11.
• What time is it really?
Points to consider
1. The ability to visualise representations,
pictures or images and then adapt/change
them is an important tool in learning
mathematics.
2. Children need extensive practical
experiences in all aspects of mathematics.
3. Visualisation is not about blue-sky thinking.
4. Visualisation activities in YR might look quite
different to visualisation activities in Y6.
Implications for Teaching and
Learning
Teach children
how to visualise
familiar 3-D
shapes in a
variety of
contexts.

Key Messages
• Visualising is a critically important skill in
developing mathematical understanding.
• Visualising does not tend to appear in
published schemes.
• As teachers we need to ensure that we are
very aware of all the processes of
mathematics and so we must always attempt
to know what our students are visualising.
