Obstacle courses should be changed frequently to continue to build skills, use a variety of muscles, and build a variety of neurological pathways. If there is a particular challenge it is fine to keep it again in your next course until better mastery is achieved. You will have fun seeing improvement happen.
Ask an occupational or physical therapist to point out important details that will help skill building be complete and effective.
BTW You can easily work in keyboarding and tracing (see printable under OT school writing section).
If you have created a new course, share it with the team. If you like this, you will like the eBooks on obstacle courses. Check them out!
