Secondary Maths Learning Materials
These are the explanations I find myself giving most often, written out properly so a student can work through them alone. They are free, they print cleanly on A4, and you are welcome to bring one to a lesson and mark it up. I add to this page as I write them.
G3 Mathematics (formerly Elementary Mathematics or E Maths)
- 2026 Cambridge O-Level Mathematics: worked solutions to Papers 1 and 2 (Note: Name of Exam changes to Singapore-Cambridge SEC G3 Mathematics from 2027 onwards) Please note: these are not full worked solutions. They are abbreviated: some parts give only the final answer, and the rest show only the key steps. The question papers are copyright and not reproduced here. PDF, 4 pages, A4.
- Number Patterns: the formula for Tn Build difference rows until one goes constant, then read the circled staircase straight into the formula. Eight worked examples, from constant 1st differences up to constant 4th, and a question to try.
G3 Additional Mathematics
Nothing here yet. G3 A Maths walkthroughs are next on my list. If there is a topic you would most like written up, tell me and I will start with that one.
