4. In the classroom
There are many possible strategies for making more use of visualisation within the mathematics classroom. There are several visualisation activities for you to experiment with in Activity 3. One teacher's approach to incorporating visualisation is given in the following case study and three-part video clip.
Case study
In a secondary-school classroom, the teacher, Peter Gates, is working with fourteen-year-old students on a topic in which they are exploring aspects of circles. This particular activity involves working out distances around a race-track.
The school is Brindley Hall, at Stantonbury Campus, Milton Keynes. Peter has a class of 27 mixed-ability students. They are his own class for pastoral purposes and he teaches them mathematics. They work on an individualised scheme, the Kent Mathematics Project (KMP) for roughly half of their mathematics lessons and participate in whole-class projects, such as the one on circles, for the other lessons. These projects help to prepare students for their GCSE coursework that they will have to undertake in subsequent years.

The students are encouraged to devise their own approaches to problems and to follow their own ideas and questions. Peter is concerned to involve the students in the mathematics they encounter, so that it becomes as meaningful as possible for them. He uses a number of devices in order to achieve this, one of which invokes their mental imagery to help them ‘see’ into a problem. Use of practical apparatus and calculators is also important to their way of working.
Activity 3
Visualisation is an important facet in all areas of the curriculum. Many people argue that we visualise what we have seen, but all our senses may be important. There are many resources that actively promote visualisation in the classroom.
In the classroom activity illustrated here the students design a solid from a few coloured cubes and then describe it. The others in the group then try to visualise the configuration and make their own.
You might like to try this activity in your classroom.
