You’re so Venn…

You’re so Venn…

The last section for the year that we are learning in the Grade 10 Mathematics class is Probability and Venn Diagrams. This section is actually really important to our everyday lives, giving us insight into questions like… ‘What the Weather is going to be like tomorrow?’ or ‘Will the Orlando Pirates win the next Soccer Match?’ The Grade 10’s have learnt[Read More…]

Using graphs to show data VISUALLY!

Using graphs to show data VISUALLY!

In Grade 10 Computer Applications Technology class we have been learning that you can enter data into an Excel worksheet and then visually represent it in the form of a graph or chart. Graphs are easier to understand and interpret than raw data, especially when you are working with large amounts of data. You can also compare various sets of[Read More…]

Man and Computer: Built in the spirit of perfection

Man and Computer: Built in the spirit of perfection

This week we had an amazing lesson incorporating Multiple Intelligence’s (MI) with our Grade 10 CAT class. Multiple Intelligence uses the idea that “Intelligence” can be determined in many different ways and not just from the traditional “IQ test”. We started the lesson by learning about the different locations in the world of famous technological inventions. The class soon realised that[Read More…]

Keep calm and ace those exams!

Keep calm and ace those exams!

It is always recommended that just before you start writing a test/exam that you put the body into a focused and relaxed state. During this past week, I have been testing 2 Techniques on the Matrics to help them focus before the exam begins. I have been getting very positive feedback from them, saying that it really helps them to[Read More…]

Databases are widely used throughout the world. Clothing stores have massive databases in which they keep records such as the prices of items and the amount of items in stock. Even schools use a database to keep track of all the learners records including results and contact details. This week the Grade 11 CAT students have been learning how to restrict[Read More…]

Why is the Linear Inequality always hungry?

Why is the Linear Inequality always hungry?

The Grade 10 Mathematics students have been recently learning about Linear Inequalities. We’ve discovered that Inequalities are very similar to Equations but instead of finding just 1 or 2 solutions we can find infinitely many solutions to the problem. Also Inequalities contain a < or > sign whereas an Equation only has a = sign in the problem. For example x[Read More…]

Computer problems… WE can fix it!

Computer problems… WE can fix it!

Do you know what to do if your computer doesn’t want to turn on? Bought a new keyboard and don’t know which port it plugs into? What if you can’t seem to close an application — or can’t hear any sound from your speakers? Whenever you have a problem with your computer, don’t panic! Before you take it to the repair[Read More…]

Completing the Square with Trinom-nom-nom-nomials

Completing the Square with Trinom-nom-nom-nomials

Last week the Grade 11 Mathematics students started Completing the Square for quadratic expressions. Basically we are trying to convert a trinomial (an expression with three terms) into a perfect square binomial (an expression with two terms). The Grade 11’s have been finding this concept quite tricky and they’ve realised it involves a lot of hard work and concentration. This concept[Read More…]
