IT’S NOT FAIR!
Mr Asher gave us a
problem. He said “It’s not
fair! My favourite colour of
Smarties (red) always
seems to have the least
number of sweets in each
tube. Is it true?” In pairs,
we counted all the
Smarties in a tube (lots of
Smarties – over 450 in the
classroom!). Then we sorted
them in different ways.
After we had sorted
them, we put the
information into a
spreadsheet and used
the ‘SUM’ function to
find a total.
