'Name the Children' printed from http://nrich.maths.org/
Many of you sent in your answer to this
problem, but very few of you told us how you did the problem.
Remember, it is important to tell us what you did to solve the
challenge so that someone else could follow it if they were stuck.
Georgie C from St George's School did send us details:
I started by writing down all the features the anonymous children
had (i.e child 1 has black hair and a green top) and wrote down all
the possible names each child could have.
The first clue said that Ella and Fred had fair hair. I crossed off
the names Ella and Fred leaving me with 2 fair headed children who
were going to be Fred and Ella. As one is a girl's name and another
a boy's, it was easy to tell which name belonged to who.
Next, it said Ali, Baxter and Greta have black hair meaning that
the 3 black haired children were Ali, Baxter and Greta but you
don't know which is which.
The next clue tells us that Ali, Chris and Danny have red game
shirts. We have already worked out who Ella and Fred are, leaving
us with Ali, Chris and Danny. In the previous clue it said that Ali
was a child with black hair and as there is only one child with a
red t-shirt and black hair, this must be Ali.
In the fourth clue it tells us that Baxter and Ella are taller than
the others. We know who Ella is, leaving Baxter to be the other
person which then means Greta is the one with black hair at the
start of the line.
The final clue says that Ali, Chris and Helen are smaller than the
rest. We know who Ali is, leaving Chris and Helen. It said earlier
that Chris wore a red t-shirt leaving the other small person to be
Finally, Chris has to be the smaller one out of him and Danny
leaving you with the following line up:
GRETA CHRIS BAXTER DANNY ALI FRED ELLA HELEN
Well done, Georgie. Well explained solutions
were also sent in by Azure from Hanoi International School and Plum
from Ardingly College Junior School.
