A good friend of mine gave me THIS book a few years ago and I just love it.
If the World Were A Village: A Book about the World's People.
Here is an excerpt about the world's school:
Schooling and Literacy
A school bell calls young people of the village to school. But for some children, there is no school to go to, or they must work instead, to help feed their family.
How many people in the village of 100 go to school?
There are 38 school-aged villagers (ages 5 to 24), but only 31 of them attend school. There is 1 teacher for these students.
Not everybody in the global village is encouraged to learn to read, write and think. Of the 88 people old enough to read, 71 can read at least a bit, but 17 cannot read at all. More males are taught to read than females.
And it's so sad because its realistic.
