First we decided to make a cube to physically test our theories and
ideas.
We spotted that there were two impossible routes. These were: the
rotating $4$s down the middle and the $1, 4, 1$ combination going
across.
These are impossible because you can't have two $4$s next to each
other as there is only one four on the dice. The other is
impossible as to get from $1$ to $4$, and then to $1$ again, you
would have to double back on yourself.
Next, we had to think of a route that bypassed these two impossible
combinations. We thought that we could start our route with the $4$
in the impossible $1, 4, 1$ combination so that we didn't have to
complete the whole impossible combination.
We checked that our theory was correct by rolling our cube along
the grid. As we rolled it, we wrote the next number in the grid as
a reflection on the next face of the cube. We tried starting at the
top $1$ and the centre $4$ and we found that this route works both
ways.
Thank you Hanaho and Emilia for explaining how
you did it and what your thoughts were and well done all of
you!
