Harriet sent in this solution. Well done!
She has explained her method in the middle of the grid.
Can you see how she did it?
Is this the only solution using her method?
Early in 2015 we had a solution from Ciaran and Alfie in year 5 at Petts Hill Primary In the U.K.
Thank you for this latest solution and the way it was illustrated.
At the beginning of 2016 we had two more solutions. These came from Collaton St. Mary School
Finley and Charlie sent in the first and Archie, Harrison, Huw and Younes sent in the second one.
Thank you very much for these, they're both excellent solutions. They may inspire more to come from elsewhere.
It maybe did inspire others because this email came from st. Patrick's Primary School, Sunderland
From Year 3 at Saint Patrick's Primary in Sunderland who worked together to find a solution:
