About pupil

As a whole, pupil are lively and tend to make interesting ideas.
Sometimes they are so infantly.
The number of boy students and the number of girl students is ill-balanced. (boy 23, girl 13)
This becomes my attention in managing the class.
It is difficult for pupil to concentrate on learning. If one of them starts jesting, it infects to the rest.
There is a student who is not good at speaking in the presence of others, though his voice is rather loud.
There are many students who dare not raise hands for answering though they can answer.
I keep trying to change this disposition in them.
In the mathematics class, pupil are better at number calculation than at solving problems expressed in words.
There is a student who is very quick to calculate.
There is a student who does not have completed the multiplication table yet.
