Olivia and Poppy from St Mary's School, and Yanqing from Lipson Community College all suggested that the smallest total they could find is 8 using the route: 1-2-1-1-1-1-1.
Eva who goes to Benenden School sent in the largest total and describes the route:
1 (right to) 2 (right to) 1 (right to) 2 (down to) 1 (left to) 3 (left to) 3 (left to) 2 (down to) 1 (down to) 2 (right to) 1 (up to) 1 (right to) 1 (down to) 3 (right to) 1 Total = 25
Eva also sent in a path that made 12:
1 (right to) 2 (down to) 3 (down to) 1 (right to) 1 (down to) 3 (right to) 1
Emma from Maryhill High School found a different route that also has a total of 12:
Children at New Earswick Primary School found some other solutions to make 12:
Perhaps one of the last two is the same as Emma's - but well descibed, Alex, Ben and Josh.
