Parents:
All learning activities contribute towards your child’s academic achievement. Tasks including this
homework guide are used as a regular part of the teaching and learning process to clarify your child’s
understanding of concepts, to remedy their misconceptions, and to support their further learning and the
development of deeper understanding.
 You can assist by asking your child to show you the online revision tasks for each week.
 When the weekly tasks have been completed, please sign the table to indicate they have
completed the task for that week.
 You child will ALWAYS have Science revision.
