The 2012 Annual National Assessments for Grade 9 include a question to select a particular type of number from a list. Each of these carries one mark only, and thus not much is expected from the learner except to circle their choice on their answer paper. This blog article will talk you through two worked examples.
The history of mathematics is outlined from two perspectives.
The first perspective is through the mathematicians who have contributed to the development of mathematics through the ages, such as (Pythagoras, Euclid, Archimedes, Fibonacci, Newton, Descartes, and many others).
The second perspective examines the development of the most important ideas in mathematics, such as the origination of the digits we use 0, 1, 2, … 9; where arithmetic comes from; how the digit zero came into widespread use; and the development geometry, algebra, and the calculus.

Throughout the the world schools have been closed to prevent the spread of the COVID-19 virus. This closure will likely be for a long time and yet we still need to continue with our learning from our homes.
I suggest that you take this time to build up your MENTAL MATHEMATICS knowledge, which means that you remember many calculations as facts rather than having to work them out by hand or with the help of a calculator.
It has been my experience, in more than 50 years of tutoring mathematics, that mental mathematics expertise is not well developed and I find many Grade 12 Mathematics learners who do not know the multiplication table up to 12×12 and who use their fingers to count out basic calculations such as 6×8. This situation is not acceptable and you now have the time to work on this with other schoolwork largely suspended.
I am providing many short lessons, with documents for downloading, which will help you to develop your mental mathematics skills and you can work on these by yourself and with help from your parents. You may also wish to work with your fellow learners in a group using social media apps.

These lessons will be updated over time so please come back often to see how this is being updated. We will soon be asking you to create an account (free!) so that we can keep you informed by our newsletters on the learning of mathematics.
