Boiling Eggs
So, if one egg that takes 6 minutes will 6 eggs take six times
longer? No, six eggs will take 6 minutes, says Nick , a pupil at
Wesley Preparatory School as well as Mithran from Mill Park
Heights Primary School , both schools in Melbourne, Australia.

Birds on a Scarecrow
Joanna and Becky from Dalwood Primary School think, "There are no
birds left sitting on the scarecrow's head". Mithran from Mill
Park Heights Primary School, Melbourne in Australia agrees. But,
why ever not? "Because the others will escape (fly away)",
explains Basak of Mef School in Turkey. Quite right, scared birds
don't stay around to be captured!
Writing Numbers
No, of course eleven thousand, eleven hundred and eleven is not
written as 1111011! It was hard to fool you with this one. As
Simon from Tattingstone Primary School showed 11,000 + 1100 + 11
= 12111. An answer shared by several other mathematicians.
Apples in a Bowl
If you took 2 from 11 apples how many apples would you have? Are
you subtracting to find a difference, or are you taking apples??
Thomas and Lewis , from Dalwood Primary School, thought carefully
about this and came up with two possible answers. "If it's your
bowl you would still have 11 apples but 2 would be out of the
bowl. But, if it isn't your bowl, you would you would only have
the ones you had taken. So you would have 2!" Can't fool these
friends!
Pennies in a Dozen
There are indeed 12 pennies in a dozen. In this problem we didn't
have 96 dozen and one half dozen but 96 pence and six pence.
There were many solutions to that problem and all with the same
answer! That's quite unusual to have total agreement.
Laying Eggs
Several ways to solve this problem were evident from the work
sent in. Simon of Tattingstone Primary added 11/2 hens and eggs
four times to get six eggs from six hens in a day and a half.
Then as Simon says, "Do it all again!" Therefore, six hens take
72 hours or 3 days to lay a dozen eggs, calculates Mithran from
Mill Park Heights Primary School. What do Hens Say? Was the
answer 12 or was it 20? These were sonme of the possibilities
sent in. Or, if we take the question literally, is Marion of
Tattingstone Primary School correct? "None of the hens can say
they have the same colouring as another - because hen's can't
speak!" I'm with you on that one Marion. Thank you, also, to
Jackson from Wesley College which is in Melbourne, Victoria in
Australia and to Joanna from Dalwood Primary School.
What Day?
This was a tricky one to unravel as the different answers showed.
Was it Thursday, Friday, Saturday or Sunday? Yesterday's tomorrow
is today. It seems that today is Friday. So, tomorrow is
Saturday. The day after tomorrow's yesterday (which is today -
Friday) must be Saturday. I think!!! The people who worked on
that confusing muddle of days need mentioning: Roger, Rebecca and
David, Matthew and Chris, Mithran, Simon and Marion , as well as
Zoe and Winston .
Coins in a Bag
You knew there was catch to this one. "Make 1 of the children
give the coin back to you and put it back in the bag", was one
suggestion. But if you want the children to each have a coin you
could do what Marion from Tattingstone Primary or Joe and Frances
from Dalwood Primary School suggest: "If there were six children
you could give one coin to five children and give the one that's
left to the sixth child - still in the bag!"
