Introduction

This week students will extend their understanding of the number system and learn to apply it to solve problems involving right-angled triangles.

Students:

• are introduced to rational and irrational numbers

• will create a visual representation of Pythagoras’ Theorem

• explore the relationship between 3 sides in a right-angled triangle 

• will solve equations to find the missing value using Pythagoras’ Theorem.

Outcomes:

• MA4-1WM - communicates and connects mathematical ideas using appropriate terminology, diagrams and symbols

• MA4-2WM - applies appropriate mathematical techniques to solve problems

• MA4-16MG - applies Pythagoras’ theorem to calculate side lengths in right-angled triangles, and solves related problems

1. Overview of square roots and surds (60 mins)

Outcomes:
