My school entered a maths competition and (although I was in year 5 and they could enter year 6s) they chose me to enter. 3 other children entered who, like me, were in year 5. This was because the year 6s aren’t as clever.
We went to Explore Learning and were told what the puzzle was. It seemed easy but it was actually hard. The puzzle was “You have an 11×11 grid like this:”
“And you have to cover as many tiles as you can. You have to touch the black tile once you have finished.” Easy? Think again. “You can’t go on more than 2 of the same colour tiles until you touch a different colour tile and you cannot move diagonally.” Here is an example:
We covered 116 tiles which was better than the question writers (Cambridge University). I bet you can’t beat 116.
(A fellow blogger Diaaaana, did this with 119 moves until I noticed that I had forgot to mention the “no moving diagonally” rule. I have now added this above. Please everyone, try again and try to beat 116).
The question was a lot harder and we came 16th in the country. At least we were the youngest so we are probably the best mathematicians for our age.
