The school in the past

Here's a text about the school in the past....

First of all at the school in the past the libraries were small in a dition there weren't computers, smartphone, tablet and interactive white board, so it was difficult to study without these instruments. The classes were full of students, in each class there almost forty students. The students used to have a good hand writing, were respectful with teachers, there were strict rules for example the students talk with the classmate, they must respect the teachers and during the lessons they cannot ate a chewing gum. If they didn't respect these rules, the teacher punished them getting hit with the ruler, a come on sit them in a corner for a short time with a hot on their head. The students won't to school on a foot or by bike, there wasn't male teacher especially in the primary school, the students are can uniform, they used to have only a book and they wrote with a ink pen. The desks were of wood, they were very eavy , the classes was just for boys and for girl. They used the abacus because didn't exist the calculator. Finally they learned by heart.

Pay attention
Consider the grammar and lexical mistakes...


First of all, IN  the school OF the past  libraries were small.
In ADDIdition, there weren't ANY computers, ANY  smartphoneS, ANY tabletS OR interactive whiteboardS, so it was difficult to study without thOSE instruments. 

Classes were full of students, in each class there WERE almost forty students.  Students used to have a good handwriting, and were respectful TO teachers, 

There were strict rules, for example  students DIDN'T USE TO  talk with theIR classmateS, they HAD TO respect teachers and during the lessons they COULDN'T  eat  OR  CHEW gum. If they didn't respect thOse rules, the teacher punished them, hitting them  with a ruler, or forcing them to sit in a corner for a short time with a HAT (a DUNCE CAP) on their head. 

Students USED TO GO to  school on  foot or by bike, there were  male teachers for boys and female teachers for girls,  especially in the primary school, 

WHAT's MORE,   students WORE uniformS, they used to have only a book and they wrote with aN ink pen. 

The desks were MADE  of wood, they were very heavy , classes were just for boys or  for girlS. They used the abacus because theRE WERE NO  calculators . 

Finally students  learned mainly  by heart.
