TERM 1 (2014/15)
Year group: Year 8
Subject: Physical Education
Year 8 Homework 2014‐2015
Homework is essential part of the learning
process. Grange School has a consistent
homework policy across all subjects and
we look for parental support in helping to
make sure homework and assignments are
completed when required.
Homework is important because it:
• Helps to consolidate and extend what is
learnt in the classroom
• Helps teachers to assess student's
learning
• Develops individual learning
responsibility
• Develops research skills
• Prepares KS3 students for IGCSE study
Homework Marking
Students receive a grade for each piece of
homework. The marks are then used as
part of the overall assessment of the
student’s individual progress.
Marks are from 1 to 5:
5 – Outstanding
4 ‐ Very Good
3 – Good
2 – Satisfactory
1 ‐ Poor/Not completed
Task 1
What is physical fitness?
What is the component of physical
fitness?
Task 2
Research and with a brief
explanation how to improve a good
sprinting start.
Task 3
(a) List 5 techniques of a sprint start.
(b) Research and with a brief
explanation 10 muscle that are
needed to carry out a correct triple
jump and high jump techniques.
