This document outlines the objectives for a three-lesson unit on trigonometry for Year 9 students. Lesson 1 introduces trigonometric ratios to calculate angles and the use of mathematical software. Lesson 2 applies trigonometry to solve right triangle problems and introduces setting up a wiki. Lesson 3 has students take an online assessment on trigonometry and determine appropriate wiki content on real-world uses of mathematics.

2. Intro
Introduction:
• Year 9 Mathematics
• Trigonometry
 The “Pythagoras and trigonometry” part of the “Measurement and
Geometry” component of the Year 9 Australian Curriculum for Mathematics
• Using trigonometry to find angles in
right angled triangles and applying
trigonometry to solve abstract and real
world problems. Integrating ICT via the
use of mathematics software and
Wikis. 2

3. Specific objectives
Lesson 1:
At the conclusion of this lesson each student will be able to:
1.Calculate acute angles in right angle triangles from known side
lengths using trigonometric ratios
2.Appreciate the use of mathematical software as a learning and
problem solving tool
3.Understand a set of software related concepts, including:
 What are system requirements for a software program
 The advantages of web-based vs DVD installed software
 Why does software need a password and a user ID?
