  1. Year 9 sets 3 to 7 Maths Homework – autumn term Each week there is to be homework set, due in the day the teacher requests. The topics for each week are listed below. • Please note: The date given is the date which the work is being taught in class. The due date may well be the following week and is at the individual teachers discretion. • Each mymaths homework is divided into 3 sections, A B & C. • A is for all pupils to attempt. • B is slightly harder and for most pupils to attempt. • C is the higher level work for some pupils to attempt. • (Your teacher will tell you which parts you should work up to) • ONLY SPEND AROUND 30mins! If you are struggling, try using mymaths, if this doesn’t help then ask someone who can, preferably your maths teacher (BEFORE IT IS DUE IN!) • Every other week (roughly) is a Mymaths based homework. These are to be done online using your own login and password. • The initial school login is testwood and password is pentagon (this may change). • Please remember to click ‘checkout’ at the end so your work is submitted. • If you do not have the internet at home please use the learning resource centre (open until 4pm Monday – Thursday, 3.30pm Friday) • (With thanks to Kevin Jobson, JCasey and tes contributors)
