'Sitting Round the Party Tables' printed from http://nrich.maths.org/
We had some really good ideas sent in, some
that were illustrated well using the computer. From Kent College we
had Primrose and Charlotte, Sophie and Nia, Stephanie, Nandini
Well here we have a superb piece of work, sent
in by Abi and Charlotte from the same school, that I would advise
people to look at for working investigatively on this activity.
When we first looked at the problem we decided to test the
difference between the amount of sweets each table needed, and we
came up with these results.
We looked at the results to see if there was a pattern in the
difference between the amounts of sweets. Despite the fact there
wasn't a pattern there we were determined to find a pattern. So we
looked further into the problem and saw a pattern between the
From that we could guess the next two amount of sweets
When we saw this we thought of why it could have happened.
Then we realised that a square has four sides and four squared is
$16$ so to get proof we checked with a triangle.
There is a pattern. So the difference between the difference
between the difference is always nought.
