School Life for a British Schoolboy

I leave home at 6:45 and walk 20 minutes to catch a bus to school. The journey
takes an hour because the bus has to keep stopping to pick up other students along
the way. On arriving I collect my Tablet PC from the Learning Centre and go to
my Tutor Room for registration at 8:30.
We do our early morning work while our class teacher takes the attendance
register. The attendance of every child is recorded in a special registration book
each morning and afternoon. The teacher reads out each child’s name in turn, a
child replies and the teacher writes down in the book whether the child is in school
or not.
At about 8:50 we leave our Tutor Room to go to the Assembly Hall. In the hall
we listen quietly to the music playing. Each week has a different musical theme
and the children are asked to listen out for particular things.
Every day I have a different first lesson. Normally it is English but I also have
Maths, Computers, Drama and Music and French on other days.
Every student carries a swipe card. We swipe into every lesson to let the school
know that we have attended that certain lesson and to know where we are when
something happens.
The children can bring a snack from home to eat in the playgrounds. It is usually a
packet of crisps, fruit or a couple of biscuits. We play games on either of our two
playgrounds, adventure playground or in the large playing field.
Lunch time is from noon to 1:10 p.m. Some children will have a school dinner
cooked in our school kitchen. In the afternoon the lessons resume with reading
activities. The rest of the afternoon is spent learning one or two of our other school
subjects. Afternoon lessons continue until 3:15 p.m. when we go home.
