There is an accompanying grid of 11x11 squares with each letter of the
alphabet randomly (apparently) located on intersections of squares. Hard
to describe in short but hopefully someone will know what I mean.
I tried going across 1, down 5 and down 1, across five and so on - but
generally struck no letters on the grid. I also tried 1x5=5 then counting
5 squares and so-on but again, no luck. I tried 1+5=6 then counting and
this too provided no hint. The question gives no clue as to how to
approach it (my son is home sick so I don't know if he's missing something
that may have been discussed in class in his absence).
I've scoured the net for info on codes and ciphers and by now I'm feeling
confident I could reliably hack into NASA - but I haven't got a clue where
to begin with these primary school questions! Any pointers anyone?

For a nine-year old I can't imagine that it's anything more complicated than
a row/col reference. If this doesn't match, your best bet is to ask the
teacher. Alternatively, you could try posting the entire grid and questions
for someone here to have a quick look at.

There are 4 starting corners and 2 orders for which is horizontal and which
is vertical. If none of those 8 pan out, there's also the distant
possibility they numbered the rows and columns starting with 0.
Got a scanner? You could post the actual grid...

The above may not (yet) represent the opinions of my employer.
Yep. I'm a dill. I tried counting from top left, bottom right and even
from the centre - but not from the bottom left. Guess where the origin
was??!!
Thanks anyway.

Yep. Problem solved. I'd tried a bunch of starting points except the
bottom-left corner as it turns out. It was one of those things where the
solution was blindingly obvious yet for some reason I didn't choose THAT
corner as a starting point.

I know you have the answer, but this reminded me of a cipher I used to use
as a child of about that age which fooled absolutely everyone. I highly
recommend it to parents of children who are into codes. In fact, I'm going
to present it as a puzzle (I doubt it'll take too long for people here to
crack, but still!) I'll give the easiest version here - there were cleverer
variants. So: can you decode the following text? (A hint follows after the
puzzle and some spoiler space)

Hint after spoiler space...
It's a very simple substitution cipher.
Danny
No replies to this one, so I'll give the answer (original puzzle is spoiler
space)
The cipher is about as basic as you can get:
A= 1, 0
B= 2, 0
C= 3, 0
...
Y= 5, 2
Z= 6, 2
.= 7, 2
,= 8, 2
?= 9, 2 (although it doesn't appear in the above text)
The first and last digits are arbitrary and just decoys. So the first word
is 8, 0; 1, 0; 3, 1, or HAM.
As I say: a very good cipher for kids because it's so satisfying :)
