These are all resources I have created for Tiffin's Year 10 group, sets 1-2, who do GCSE at the end of Year 11 as normal, but also do an additional IGCSE Further Maths qualification. Resources are suitable for the new 1-9 GCSE.
Some resources are older ones I've used in previous years, and will be updated prior to teaching them.
Volumes & Surface Area (GCSE)
Covers all aspects of the GCSE curriculum, including algebraic problems where volumes/surface areas are equated.
Covers similar shapes, scale factors for area and volume, and changing between units of area and volume. [Newly updated 7th March 2017]
GCSE Scale Factor of Area/Volume & Units
Covers all aspects of GCSE syllabus.
Determine lower bounds, upper bounds and error intervals after rounding or truncating. Includes calculations in terms of bounds (subtracting/adding/multiplying/dividing).
Congruent Triangle Proofs
Includes harder follow up questions where you use a completed congruence proof to make subsequent justifications.
GCSE Counting Strategies
Counting by (a) systematic listing and (b) by multiplying. Part of the new GCSE specification.
