Homework Booklet
Half Term 1 L6-7
Please complete your maths homework regularly – each week
is broken into three sections. Section A, which checks your
recall of key ideas and skills Section B is a task based on
recent work and a ‘challenge’ task (a problem for you to try
and solve). Hand your work in regularly and your teacher will
let you know how well you are doing and what progress you
are making – good luck and have fun!

Dear Parent
As outlined on the front cover, mathematics homework in year 7 is
organised in a three section format. The Section B tasks are split
into different levels and your child should attempt work in line with
their working level and target. Your child should attempt Section A
and the level ____ task of Section B, each week unless otherwise
directed by their teacher – this may mean them completing
questions at one or both levels. The challenge tasks are short
problem solving activities that any pupil can attempt. These
questions are taken from ‘UKMT Mathematics Challenge’ papers –
some pupils will take part in the annual national UKMT Challenge
during year 7.
Your child’s working level at the start of year 7 and their end of
year 7 target level is shown at the bottom of this page.
Any task that has a bold heading or is marked with an asterisk (*)
indicates that the task is linked to a key area of maths, which needs
to be understood in order to contribute towards being confident
working at that level. These areas will be assessed in more detail in
lessons and formal assessments.
We hope that your child enjoys attempting their maths homework
and achieves success in the process.
