Year 10 Maths Introduction and Overview The opportunities that can come from Mathematical study are endless. The Marches Maths department aim to foster a love for the learning of Maths and we are passionate in supporting all students maximise their performance in this most valuable of academic subjects. No matter what a student s ability or aspirations there is plenty that Maths study can offer to support their future progression. In Year 10 students begin a two year route towards the GCSE Maths exam. The current Year 10 cohort will sit the new GCSE specification and will receive number rather than a lettered Grade at GCSE Maths ranging from 1 to 9, with 9 being the highest possible result. The content of the new course is increased and both Higher and Foundation routes have a higher expectation of student performance. There will also be a strong focus on building techniques for approaching and solving Mathematical problems; interpreting a problem, identifying the skill required and using a clear method and determined attitude to arrive at a solution. Year 10 consists of 6 different units of study. The skills covered are assessed at the end of every unit and students will be given targets to work on to improve further. How to support your child Students must be confident with recalling solutions to any of the 1 to 12 multiplication tables. You can help achieve this goal by verbally testing your child at any opportunity if you identify a gap in their knowledge then you should focus your questioning regularly on plugging this gap. Your child s response does not need to be instant but they should be arriving at answers reasonably quickly but confidently. The impact this will have on their mathematical progress is invaluable and students who fall short on this skill can find this subject very difficult to grasp. Students will receive a piece of written feedback in their exercise book at least once every six lessons. This will include a target or extension question to support their progress. You can review your child s Maths book for these targets or questions and encourage/support them to act on them. All students have full access to www.mymaths.co.uk. This is an interactive learning tool that allows students to learn/revise specific topics through online lessons, complete online consolidation tasks for homework that give instant results and detailed feedback. In addition to completing tasks set by teachers students should use MyMaths to work independently on their own personal learning targets. Equipment required for Maths sessions are a Pen, a Pencil, a Rubber, a Ruler, a Protractor, a Compass and a Scientific Calculator. We recommend buying a Casio FX-83 Scientific Calculator or similar. A good calculator like this one will support your child for as long as they continue to study Maths. They are available from pupil services for 6.
