Sir it seems it is easy to do what u r doing but pracrical is alttogether different.It needs lot of experiance, patience and humour like u.
I like to keep my students "loose". School is hard work... especially if you do not learn like the "typical" learner. For many, it can be so stressful, that they lock up and are unable to learn or perform at their peak level.
Regarding this part, i had so far only seen a handful of teachers who kept me loose in class nd honestly speaking , i still remember lectures by class 9th teacher who was of the same category but have forgotten some taught recently otherwise.
