Walking around the class has another advantage of easy improvement of the class in addition to prompt additional instruction.
For example, if there is need for additional instruction for the entire class, you can alter your class plan and make additions to the planned explanations before work. If the pace of the lesson is slower than planned, find out the cause while walking around the class and improve the class plan.
Most improvements found during walking around the class are small instruction points that were not noticed when developing the lesson plan. A collection of a large number of such small points will form knowhow for instruction that will have a big impact on class development. Thus, walking around the class is the first step for discovering your own knowhow for instruction.
