Teachers who do not pay attention to assignment which is been giving to our children.

Dear Boom buddies I saw this yesterday in a student assignment which show that some teachers do not pay attention to our children. It was written in the student book one kilogram thirty minutes.
Instead of the teachers marking the student wrong they rather marked the student correct which means that the student never did a correction to show that the work was wrong. After asking her who marked the book the student then explain that the work was given to them by their teacher and when he sent the homework to the teacher he didn't pay attention to it and at that moment, he marked the homework. This explains that some teachers are damaging the brains of children. I am writing this because some parents do not look at their children assignment please do check and correct them.
