The challenges are the trial and error for the route. There were gaps in between which caused the balls to get stuck. We overcame the challenge by finding a solution to cover up the gaps using more cut up toilet rolls.

We also thought of how the children can see the process of the ball running through the toilet rolls so we made a slit in the toilet rolls.

Things to improve:

Instead of using masking tape, we should use scotch tape to reduce the fiction caused by the rough texture of the pompom and masking tape.

To make it more interactive, we can wrap the board with felt cloth or contact paper, to allow the children to explore, create, and construct their own path.
