Find a great variety of ways of asking questions which make 8.
Can you design a new shape for the twenty-eight squares and arrange
the numbers in a logical way? What patterns do you notice?
Can you work out how many flowers there will be on the Amazing Splitting Plant after it has been growing for six weeks?
Lots of you sent in your solutions to this
problem - unfortunately far too many to mention everyone. Most of
you worked out the plant's height each day, which is a very good
way of approaching the problem. Here is an example of this method
from Tom who goes to Linden Primary School:
This is very clearly recorded - well
done Tom. Hannah, Grace and Ellie, who were attending Royal
Institution masterclasses, sent a very similar solution. So did
Oliver from Webbers School, Livvy (who didn't say which school she
is from) and someone from St Joseph's School in Harrogate. Ha Young
from Wesley College wrote down the same calculations in a slightly
different way, showing that doubling means multiplying by
Some pupils from Queens Crescent School also
wrote down something a little different. Rather than recording
multiplication, they representated the calculations as addition,
In other words, doubling a number, or
multiplying it by two, is the same as adding it to itself. Very
well done all of you.
