In my experience, students, in general, find the concept of a mean straightforward to calculate and understand. However, the mean alone does not provide a complete picture of a set of data. To achieve this, a measure of spread is also required. The range is the simplest measure that can be used for this. Not […]October 1, 2018

Solving problems with angles in parallel lines is like solving a murder mystery. One clue leads on to the next and the next until the murderer is found. However, it doesn’t end there. The detectives need to explain their reasoning in court using the relevant laws and procedures should the murderer plead not guilty. If […]September 10, 2018

An equation is when one expression, or term, is equal to another. To solve an equation means to find the value of the variable (represented by a letter) that makes the two expressions equal. There are two types of equations for secondary school mathematics, linear and none-linear. In this blog I write about how I […]
