Graphing Linear Functions in Grade 10.

Graphing Linear Functions in Grade 10.

During the past week the Grade 10 Mathematics class has been practicing drawing Linear Functions, by using either the “Table Method” or “Intercept Method”. It really helps to visually see the relationship between the x and the y co-ordinates as they are plotted on the Cartesian Plane. A function is a mathematical rule by means of which each element of[Read More…]

Technology in Education: Then vs Now

Technology in Education: Then vs Now

Who said technology hasn’t changed the way we learn? Then: When I was at school the teacher wrote class notes on the chalkboard and used the overhead projectors to show printed notes or illustrations. Using an overhead projector in class Writing out maths equations on a chalkboard Now: At Silvermine we use different aspects of the latest educational technology to make sure that the learning experience[Read More…]

Which side will the “x” be on in Linear Inequalities?

Which side will the “x” be on in Linear Inequalities?

The Grade 10 Mathematics students have recently been learning about Linear Inequalities. We have 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 an = sign in the problem. For example[Read More…]

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…]

Probability: What are my chances?

Probability: What are my chances?

Have you ever wondered as you look out your window what the chances are that it is going to rain that day? Or what is the possibility of me winning the Lotto? These questions and more can be theoretically answered through the study of Probability. Our Grade 11’s are busy working through this section at the moment in Mathematics. In[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…]
