the children to create number sentences to generate their own special
numbers. For example they could use their date of birth to create
their own special number, e.g.
(Year) - (Day) + (Month) -> 88 - 26 + 5 = 67
How many different special numbers can they create by forming different
number sentences using the same generator numbers. What other numbers
can they think of in their life that have special significance?
(e.g. house number, age they were when they went to Disneyland etc.)
Can they use these to create special numbers? Lots of possible discussion
