is very useful when you want to give pupils opportunities to explore number patterns in their own way. There are various ways of exploring this activity with no particular 'right' way.
The way in which you introduce this activity will depend on the children you are working with. It would be helpful to show the arrangement of numbers in the problem on a board (if a big group) or on paper (if a small group).
Some more experienced pupils may be asked "Why are these sequences like they are?"
Less experienced younger pupils can be asked simply "What do you notice about the answers we've got?"
Generally you can ask "What could you do now?"
An extension may be suitable for some pupils that comes from comparing the results from the sequences that we get when the houses are grouped.
Some pupils may need number cards in front of them and calculators to free them up to think creatively.
