This is a resource worked on by Mundher Adhami whilst at King's College University and could be seen as complementary to Thinking Maths. It is currently being updated by the Nuffield Foundation. The resources can be downloaded below.
The series is a complete teacher assessment scheme covering upper Key Stage 2, Key Stages 3 and 4 and graded using an attainment system created pre-National Curriculum (Levels 2-10). It offers assessment based on a creative approach to mathematics in the classroom. This is achieved through the emphasis on students being able to demonstrate their mathematical learning through students' investigational and problem-solving activities. This results in greater motivation and enjoyment on the part of the students.
Graded Assessment in Mathematics can be used alongside any primary or secondary mathematical scheme. Assessment is measured against GAIM topic criteria which are clear statements describing significant steps in mathematical learning. These statements elaborate on the Statements of Attainments of the National Curriculum, and are designed to reflect the intermediate steps of a student's progress in mathematics. The topic criteria are backed up with topic tasks, questions testing a student's satisfaction of a specific criterion. GAIM is designed to ensure that any further changes in reporting requirements within the National Curriculum can be accommodated using the materials provided in this pack.
The Nuffield Foundation are currently revising these materials and have renamed them Applying Mathematical Processes.
