Key Stage 4

 Assessment 3

Intent

The intention of this unit is to start the process of readying students for the GCSE Mocks and exams.

There is no new content in this unit, instead students focus on a collection of problem solving strategies that will help them with a broad range of high frequency exam questions.

Implementation

In class students will look at problem solving stratgeies using tables, ratio and algebra. Students will refresh their knowledge from KS3 and Year 10, before seeing how a similar problem solving approach can help with a wide range of problems.

Every week students will also complete a Weekly Ten worksheet, which consolidates and strengthens their understanding of 10 key exam topics appropriate to their target grade.

Homework during this unit is not directly linked to classwork but is based on an assortment of exam practice questions which will help students prepare for the mock exams in term 2. Each homework task has a QR code to link to the MET site where students can get help.

Impact

The impact of this unit will be measured by the mock exams in term 2. Students will sit three 90 minute papers in exam conditions.

Mock exam questions are drawn from the whole GCSE syllabus, but there will be plenty of opportunitites for students to apply strategies they have learnt in lessons, through weekly tens and hoemwork.
