Algebra Resources

Back in March, I wrote, Number Resources, still very much a beginning and a work in progress, I have been reorganising pages. Making things easy to find is a never-ending task! Having written this blog since 2009, many older posts are still very useful – I want to make those easier to find.

Hence some new pages, the first created was Number under GCSE (14-16). This shows GCSE content and links to some favourite posts, also to sites that are particularly easy to search by topic. Further posts and resources and sites will be added, this is quite a project, but watch this space!

I have now added Algebra which brings some posts together such as:

Algebraic Notation


Factorisation of Quadratic Expressions

Lyszkowski’s method

Simultaneous Equations

White Rose Maths – Exemplar Questions

Iteration

Transum Mathematics – Iteration

Proof

Activities to help learn reasoning and proof

Links to sites that are particularly easy to search by topic for Algebra are included, including some brilliant Underground Mathematics questions to challenge your GCSE students.

Underground Mathematics Algebra Review Questions (old O/AO level).
Some favourite tasks to challenge your GCSE students:
