Many of you sent in solutions to this problem and some of you were very creative! Remember that the paths were drawn looking from above, not the side, so the second one is not stairs.
Isabelle, aged 10, suggests:The first walk is straight. I think this could follow a pavement alongside a straight road. This might be someone walking from their house in town along the pavement to a shop.
Henry from Cardiff High School had some different ideas, but just as good:I think that path number one, you must have walked in a straight line because you were in a narrow corridor or in a narrow area or you must have been in a very straight line waiting for something like a film or something like that.
Will from Shrewsbury House School suggests:1. You are going on a straight path, maybe down a Roman Road?
I'm sure you can invent more of your own, but thank you again to those who did send in descriptions.
