## GCSE Mathematics

GCSE Mathematics is a modular exam which is examined through the CCEA Examinations Board.

This course requires more problem-solving and applying mathematics than previous specifications

and introduces functional elements in mathematics.

The course gives students opportunities:

- to develop their knowledge, skills and understanding of mathematical methods and concepts
- to acquire and use problem-solving strategies
- to select and apply mathematical techniques and methods in mathematical, everyday and real-world situations
- to reason mathematically, make deductions and inferences, and draw conclusions
- to interpret and communicate mathematical information in a variety of forms

- for progression, including progression to further study of mathematics at AS/A2 level.

The units all provide opportunities for students to develop and apply their mathematical skills to real-life contexts. Pupils choose one unit in Year 11 and one unit in Year 12. The grades that students can achieve depend on the units that they sit for assessment.

In Year 11 pupils choose one unit from:

- Unit T1 or T2 Foundation Tier
- Unit T3 or T4 Higher Tier
