Think B4 you Click

With online communication exponentially increasing, so too have the dangers of communicating online. Keeping oneself safe online has become a priority, with the golden rule to never give out any personal information. As a part of the Grade 11 CAT assessment this term, the students were asked to investigate ‘online safety’. On Wednesday they presented their findings in the form of[Read More…]

EXPLORING the many uses of Microsoft Access Databases

EXPLORING the many uses of Microsoft Access Databases

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…]

Mathematics off with a BANG

Mathematics off with a BANG

The Maths department is starting the term off with a bang! The Grade 12’s were astounded when they found out that they had been given homework on the first day of term. The Grade 10’s are starting to learn about the number system which will greatly help them in the future when we go onto the more challenging section of Algebra.[Read More…]

Effective Study Habits to Combat the Exam Blues

Effective Study Habits to Combat the Exam Blues

The SMA pupils are in the middle of writing their final year examinations.  This is always a very stressful time for teenagers. They have to study a vast amount of work in a short amount of time. About a week ago in our Grade 10 Life Orientation class we learnt about implementing good study techniques for the upcoming exams.: 1. You need to[Read More…]

Calculus? Easy as π

Calculus? Easy as π

Calculus can be defined as the study of the “rate of change”. This is a very useful concept as it is revisited many times in Tertiary Studies involving the Science and Business fields. If you want to be an astronautical engineer, a pharmacist, an actuary or a biologist – you need calculus! One of the most practical uses of Calculus[Read More…]

Let’s Talk Excel

Let’s Talk Excel

In Grade 10 CAT this week we started Microsoft Excel. Excel is perhaps one of the most important computer software programs used in the workplace today. That’s why so many workers and prospective employees are required to learn Excel to enter or remain in the workplace. The great thing about Excel, is that it can perform formula-based calculations and many other complex mathematical[Read More…]

Learning About Linear Functions

Learning About Linear Functions

A function is a rule by means of which each element of x is associated with only one element of y. It is possible to “draw” these functions on a Cartesian Plane using x and y co-ordinates. During the past week the Grade 10 Mathematics class has been practicing drawing Linear Functions, by using either the “Table Method” or “Intercept[Read More…]
