Knight Moves

Pupils aged 11 & 12 were asked to solve a simple maths problem. This Scratch app was used to help the less able find a way into the problem in a fun way.

The question posed to the pupils was:

On a 10x10 board, what is the fewest number of moves needed to visit every squared, cubed or series of numbers of your choice? Easy, except you may only move as a Knight moves on a chess board. Is there any pattern in the number of squares to visit and the least number of moves and what routes did you take?
