Alistair and Jessica at Randlay School in England said:
We did this by finding the largest number 6/6 and then finding another domino with six and any other number on it. Over to Jess.
We found interesting patterns and also played a game of dominoes. Alistair wasn't sure at first but I soon taught him!
