Unit 2 General Maths - Trigonometry decision mastery

Two QCAA General Maths trigonometry resources – formula selection worksheet & decision tree – ideal for Unit 2 revision and skill mastery. This bundle combines two high-quality, visually engaging trigonometry resources designed specifically for the QCAA General Mathematics Unit 2 syllabus. Perfect for senior secondary teachers in Queensland, these materials help students develop the confidence and skills to choose and apply the correct trigonometric formula for a given problem. Included in the bundle: * Trigonometry Formula Selection Worksheet (with answers) – Students practise identifying whether to use the sine rule, cosine rule, or area of a triangle formula based on the information provided. Scenarios include both finding unknown sides and angles, with varied question types to encourage deeper thinking. * Trigonometry Decision Tree / Flowchart – A clear, student-friendly visual guide showing the step-by-step logic for selecting the correct trigonometric formula. Ideal as a teaching tool, revision aid, or classroom wall display. Key features: * Fully QCAA General Mathematics Unit 2 aligned * Focus on sine rule, cosine rule, and area formula for non-right-angled triangles * Differentiated question styles suitable for mixed-ability classes * Answer sheet included for easy marking or self-assessment * Professional, clear design that enhances understanding * Suitable for Year 11 General Mathematics but also useful for Year 12 revision or other senior pathways These resources work perfectly together – the decision tree provides the conceptual roadmap, while the worksheet gives students ample opportunity to put that process into practice. This makes the bundle ideal for lesson delivery, homework, revision, or exam preparation.
