Let's suppose that you are going to have a magazine which has 16
pages of A5 size. Can you find some different ways to make these
pages? Investigate the pattern for each if you number the pages.
This challenge is to design different step arrangements, which must
go along a distance of 6 on the steps and must end up at 6 high.
Can you design a new shape for the twenty-eight squares and arrange
the numbers in a logical way? What patterns do you notice?
I was with a class of children in Bromley near to London, when I
suddenly came up with this idea, and I put it to the youngsters at
the school. They did a lot of work on it so I thought I'd share it
It's all about $64$!
Lots of you know that $64$ is $8$ times $8$. So if you were
asked to write down all the numbers up to $64$ you might decide to
do eight lots of $8$ . [It's a bit like $100$ in that you may well
write ten lots of $10$ to get up to $100$ and produce a $100$
I suggested to them that they tried writing the numbers up to
$64$ in an interesting way so that the shape they made at the end
would be interesting, different, more exciting ... than just a
square. Here are the ones that some of them came up with to show
that the numbers could be arranged in an interesting way.
Most of them, as you see, ended up with shapes that were not
squares. Those that did end up with an $8$ by $8$ square put the
numbers in an interesting order into the shape.
When they did that they were then asked to made a tile [or
frame] that was made up of four squares.
Here are some examples:-
The idea now was to place one these tiles/frames somewhere on
the table of $64$ so that it covered four numbers. [The tiles were
made so that the squares were the same size as the squares on each
of the numbers in the $64$ table.]
The numbers underneath the tile/frame were added up and
recorded. The tile/frame was then moved around the table of $64$ to
different positions and each time the total of the four numbers
underneath was recorded.
Well that's what you need to do. It's fun creating new $64$
tables in different shapes.
Now comes the investigative part ...
Explore by looking at the totals that you've found and and think
about any relationships that you notice.
You then need to think about why these sets of answers are
occurring. The youngsters at the Bromley school found lots of
things out ... now it is your turn to do the same.
Lastly of course you need to ask, "I wonder what would happen if
