5 Tips to Avoid Careless Mistakes for Maths (Tip #3): Watch Your Units

Maths Tips - Watch Your Units

Another culprit is using the wrong units, i.e. the Unit of Measurement (UOM) in calculations. This frequently occurs in questions or problems involving rates or quantities such as speed, distance, time, money, and measurements of weight, length, etc.

The likelihood of a UOM-related CSM (Careless Stupid Mistake) increases when you do not use units in your working or statements. In most cases, students trivialise the importance of UOMs and in some cases totally ignore it. Hence, it leads to mistakes. The best way to become more acquainted with UOMs is simply to use them in your calculations or mathematical statements.

In my maths tuition classes, I break down common GCE O-level maths questions into specific types or categories in order to sensitise my students to the ‘warning signs’ (among other reasons). And when they detect ‘trouble’, they immediately become prudent and convert all rates and quantities to the same units before attempting to solve the problem. Yet another CSM crushed! Woohoo! 😀
