The groups have completed their task and are now required to report back and to listen to each other’s problem solutions.

Again Dr Jodie Hunter reminds the children of the mathematical and real life problem they are solving as they transition back to the whole class context. In this way she reminds everyone of the purpose, maximises engagement and keeps the children’s thinking focussed on the mathematics.  Throughout the lesson there are examples of ‘cognitive activation’ by Dr Hunter to keep children thinking more deeply about their learning without imposing answers or leaving the children to make sense of the mathematics without support.

The Sharing Back enables all the children to hear the three different generalisation strategies of all three groups and to realise that each generalisation works.

‘I wanted them to see that you could see this pattern as growing in multiple ways  because I think it’s really important for children to be able to look at each other’s perspectives and acknowledge that there are different ways of solving a problem and different ways of seeing things.’

The whole class Sharing Back session prepares the children for the final crucial session in the DMIC lesson sequence: The Connect to the big mathematical ideas.
