    A man in Pakistan is now working to help children get an education. When he was a child, he did not go to school because he was too poor.

    It is reported that Pakistan has 25 million children who do not go to school. That is the second ­highest number in the world. Only Nigeria has more. Many Pakistani children must work to support their families.

    Mohammad Ayub was once one of those children. He is now a firefighter. He also manages a small school. VOA recently visited the school in the capital Islamabad.

    Ayub started with just one student in 1982. He saw a boy cleaning cars for days. He asked him, "Why don't you go to school?" The boy answered that his parents were dead and he had to work to help support his five brothers and three sisters.

    Ayub was also an orphan and he, too, had to work to help support his five brothers and three sisters. He said, "When my father died, everyone who came to the funeral said they were sorry, but no one helped." He sold newspapers and did other work to earn enough money to pay school fees for his brothers and sisters.

    Ayub wanted to help the young boy who washed cars, but he did not have enough money to pay the boy's school fees.

    Today, Ayub teaches many children at his school in a public park. Some of the children attend other schools in the morning, but come to Ayub in the afternoon to get help with their homework.

    Ayub has helped a large number of poor children since he began teaching. Many of them come from very poor areas near the park.

    Ayub said," I used to argue with kids who worked ' Why are you washing someone's dishes or their clothes? Why don't you study? ' "

    One of the children he advised to attend classes was Farhat Abbas. Ayub found him working with his friends about 12 years ago. "He followed us back home. He told our parents he wanted to teach us and asked them to send us to his school, "Abbas said.

    Today, Abbas is taking classes at a college and is helping Ayub.

    Many children are out of school, and those who do attend classes often get a poor education. Information gathered by an organization shows half of all Pakistani children in the 5th grade do not understand basic mathematics and cannot read a story in their language.
