Nicole from Eastwood Primary wrote to tell us how she tackled this jigsaw:

First I got all the numbers down the side which were $1, 2, 3, 4, 5, 6, 7, 8, 9, 10$ and then got the numbers for the top which were the same and put them where they were meant to go!
After that I timesed them and I then put the other pieces where they were meant to go!
