One of the POWs (problem of the week) we did was called Pathfinder. The objective of this POW was to go from one point in the upper left corner of a 4x4 and 5x5 box and find as many paths as I could that went to the point in the bottom right corner. While working through this problem, I came across a few challenges. One of those challenges was finding a path and then getting stuck on the same one for 10 minutes and then finding another one then getting back to that confusion. The way I solved this was that I went back and categorized each path by starting grid height. When I looked at each grid height, I was able to find missing components in the paths that were a specific grid height. Below is a picture of the Problem of the Week.
