My teaching strategy mainly focuses on going from beginning step by step making sure that the previous step is completely accomplished then go to more advanced levels. I also focus on the most abstract forms of the concept then add the details gradually and slowly till we reach the full and accurate form. For me example after each concept is necessary to make sure that no misunderstanding happened, and in between simple questions to support the understanding. Also teaching the student what does the error he sees mean, how it occurred and how to fix it by himself.
