AN UNUSUAL SCHOOL
Sudbury Valley School in Massachusetts, USA, is an unusual school. Do you hate maths? At Sudbury,
if students hate maths, they don't study it. They go to another class, such as history or science!
Students at the school can study a lot of different subjects, like science, history, geography and art.
Students can choose to do homework, but some prefer not to do any! If students don't want to go to
any classes, it isn't a problem. There are lots of other activities at Sudbury. For example, some students
go to drama practice. Some students play instruments, and some go to the ICT room. In that room,
they can check emails or play games. They can even make their own lunch in the canteen. Pizza and
pasta are the favourite meals. Some students prefer healthy salads! Students can't leave the school, but
they can walk or play sports in the school garden. There is always something to do!
There are a few rules at Sudbury. Students can't do anything dangerous, and they can't stay at home
every day! But students are usually very happy at Sudbury. It's a popular school!
