The year 3 and 4 Mathematics Extension group at Lumen Christi Primary School in Australia sent in their excellent work in a Word Document. Here is a part of it:


The remainder can be found here:  LumenChristiSolutions.doc or LumenChristiSolutions.pdf

Aaron, who goes to Stockingford Primary School sent the following good description for the first set of dominoes:

I worked it out by putting all the zeros first like 0-0, 0-1 and so on, then putting the ones next: 1-1, 1-2 and so on.
I did that until I got all of them put together.
But I had to remember that there is only one 0-0, 0-1, 0-2 and till you get to 0-6, but you can switch the numbers round. There were 28 dominos all together.

There were a number of other emails sent in describing their work but unfortunately there were a number of slip-ups, that so easily happen with this kind of challenge. 
Thank you to everyone who sent in their suggestions.
