While there are benefits that can arise from their use, QLAs can also result in unintended consequences if not used appropriately! If you do wish to use QLAs however, read on… A24b - Recognising and using arithmetic, geometric and quadratic sequences, A24c - Recognising and using Fibonacci type sequences A25a - Finding the nth term of a linear sequence A25b - Finding the nth term of a quadratic sequence

To find the perpendicular distance from a point to a circle, simply position your ruler so that it joins the point of interest to the centre of the circle.

Whether seeing this as “doing the same thing to both sides” or a process of “breaking and repairing”, it is also important that students appreciate that it is mathematically valid to manipulate equations in many ways—and not just in ways that lead to simpler equations or even a solution. Of course, the skill is most often used in pursuit of a solution, but the skill is well worth practising in its own right.

The class QLAs (typically around 1 MB) can take data for up to 40 students while the cohort QLAs (typically around 5 MB) can take data for up to 300 students. The QLAs are otherwise identical. Because of the formulas in the spreadsheets, older computers may struggle to load or run the cohort QLAs, but should be fine with the class QLAs.
