Many schools were built between 1837 and 1901. There were several kinds of different of schools for the poor. The older usually went to a day school on Sundays. As for the younger ones a local woman in a room of her own house usually taught them. Other schools were organised by churches or either by charities. Among these there were the ragged schools, which were for orphans and very poor children. The classrooms had little fresh air because the windows were built high in the walls so the children could not be distracted by whatever was going on outside. Schools would last until 5pm with a 2hr lunch break. There would be as many as many as 70 or 80 pupils in one class, especially in cities. The teachers were very strict. The most important lessons were about the three R's Reading wRiting and aRithmetic.
