Marshall still has school despite the holiday. Here he is learning to jump according to a direction. Although you can't see another jump on the right hand side, Marshall was seated between two jumps and directed to take the jump on the left.
While this is a fun game now, it builds the foundation for searching for a child. If a child gets lost, a parent can direct the dog which direction to search by pointing.
Marshall still needs to learn "go out" which is another element of a search assignment...go out and search for (child).
Lots of small building blocks for a hopefull future.
