We had some good solutions sent in and
here are just some of them. Many pupils from Bradon Forest in the
U.K. sent in solutions. Hannah produced a Powerpoint presentation
for the solutions she found. Well done Hannah - here are her
Georgia, also from Bradon, sent in a
Word document with pictures to show the solutions. Here is what she
In the case with the three obstacles, the dog starts at the
kennel and walks on the path that leads to the signpost.
When he gets to the signpost, he goes down the path straight

In the second case, you start at the kennel and proceed to the
Next, you carry on until you reach the signpost.
Next take the path pointing at the lamppost, until you reach
Turn and head back to the signpost.
Then, you take the path round to the kennel and, when you
reach it, go down the path to the lamppost, then turn and reach
your final destination, the tree.
In the third case you start at the big tree, and go to the
Then, you continue on the path to the kennel.
Once you reach the kennel, you go to the signpost.
Then, back to the big tree and take the last path going away
from the tree.
You then go on the unused path to the kennel, and loop back to
the small tree.
To finish off, you go from the little tree directly to the
