The Sacred Cut by Suman Vaze
This was perhaps historically used to find a method to double the area of a given square. The Sacred cut produces the Silver Rectangle with ratio of sides 1:√2 which is used in A Form paper. This work illustrates how to construct the Silver Rectangle or the Sacred Cut and also gives an impression of doubling both the rectangles and the squares
This page is the link to the resources to help teachers teach Mathematics. There are various sections and some resources appear on more than one page, because classification is not exclusive.
The way it works is that the page contains some information about the resource, why it was written and how it might be used. The actual resource is then linked to. Please let me know if the links are problematic.
“To create consists precisely in not making useless combinations. Creation is discernment, choice. …The sterile combinations do not even present themselves to the mind of the creator.” – Henri Poincare
Some activities to get kids started on Algebra
Algebra at a slightly more advanced level
A page of resources about Maths rather than of Maths. Useful for teachers of “Theory of Knowledge”, hopefully interesting for all Maths teachers.
Resources for topics that lie in the senior courses in a secondary school. They have been used in IB Diploma classes, but are just as relevant for A level, Algebra 2 and above, Further GCSE etc.
Iterations, Music and Fractals
Some resources based on the idea of repeated iterations leading to interesting things such as limits, strange attractors, chaos, interesting graphics and music.
Some things that you don’t normally find on a Maths syllabus, but are fun, interesting and educational.
