Demolishing tricky SAT math questions using Desmos

In this Desmos Strategies Masterclass, you will learn how to use Desmos as a powerful mathematical problem-solving tool rather than simply as a graphing calculator. The focus is on exam-oriented strategies, speed, accuracy, and smart decision-making.

You will learn how to quickly identify questions where Desmos can give you a significant advantage and how to set up graphs efficiently to obtain answers with minimal calculations. The masterclass covers techniques for solving and checking linear equations, systems of equations, quadratics, inequalities, functions, intersections, roots, and graphical relationships.

You will also explore how to use tables, sliders, regression, graph transformations, and intersections to analyse mathematical problems visually and efficiently. Special attention will be given to recognising patterns and using graphical evidence to eliminate incorrect answer choices quickly.

You will learn how to combine traditional mathematical reasoning with Desmos strategies, rather than depending blindly on technology. We will also discuss common mistakes students make while using Desmos and situations where a conventional mathematical approach is actually faster.

By the end of the masterclass, you will have a practical toolkit of time-saving Desmos strategies that you can apply to a wide range of exam-style mathematics problems.
