Jo, Ollie, Rudi, Freya, Oliver and Joseph tackled the problem. They worked in pairs moving a counter around the board. To begin with they just said how many moves they could do it in but hadn't recorded it. They then came up with the method of moving the counter and recording the jumps on a piece of paper.
The least number of jumps they all did it in was 11 with no jumps backwards.
+3 +3 +1 +3 +2 +2 +4 +4 +2 +1 +4 (everyone got this solution)
Joseph and Oliver investigated starting with +1 followed by +4 but this resulted in 12 jumps. The last 8 jumps are the same as the first sequence of jumps but they have 4 moves before this rather than 3.
+1 +4 +1 +1 +3 +2 +2 +4 +4 +2 +1 +4
Jo was quick to spot that you didn't want to land on the box with 2/0 in it in the bottom row as going forward 2 put you on a 0/0 box. Going back 2 put you on 2/4 box so you then had to go back 4 and so on therefore adding in lots of extra jumps!
They discussed the possibility of doing it in less than 11 moves but realised that in each case bar one they had moved the maximum number of spaces. They had to choose 3 moves instead of 4 moves at the bottom of the first column to avoid the situation described by Jo above.
