This first grader is trying to get a marble to travel down a steep incline onto a flat track and then turn a corner. Repeated opportunities for testing and observation lead him to make numerous adjustments to his structure. He finally notices the problem as he removes the extraneous pathway and moves the incline over to the longer pathway. He lowers the point of release until he gets the marble to successfully turn the corner. He persists in solving the problem without appearing frustrated. Experiences with Ramps and Pathways fully engage children’s interest and determination to succeed.
