Howden School and Technology College Year 7 Mathematics Homework Booklet Half Term 2 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! Name Maths Teacher Hand this booklet in Tutor group 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, two or even three 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.
