The man was a subject teacher, and he entered their classroom to teach them. So after they nodded their heads to his statement, his voice resounded again,
"Let's get straight to today's teaching".
And that was exactly what happened, he walked to the front of their classroom properly, then the teaching began.
The first thing he did was to write today's topic on the board, then some other things followed, before he began explaining. As he was explaining, he wrote some more things on the board.
Then it got to a time when he told all of them to transfer everything he'd written on the board into their books, which they didn't waste time to begin doing.
He explained, wrote things on the board which they were transferring into their books, and before he left their classroom, he asked some questions regarding what he taught which he received correct answers to.
