Happy Trails 1 The Hunt for Angles

Published on 11/27/2013

Activity Overview

In this activity students use their local environment as a source of Mathematical inspiration. They capture digital images to demonstrate their understanding of the follow types of angles:
Acute, Right, Obtuse, Straight and Reflex

Objectives


Australian Curriculum references
Compare angles and classify them as equal to, greater than or less than a right angle (ACMMG089)
Investigate, with and without digital technologies, angles on a straight line, angles at a point and vertically opposite angles. Use results to find unknown angles (ACMMG141)
Estimate, measure and compare angles using degrees. Construct angles using a protractor (ACMMG112)

Vocabulary

acute angle
right angle
obtuse angle
straight angle
reflex angle

About the Lesson

In this activity students use their local environment as a source of Mathematical inspiration. They capture digital images to demonstrate their understanding of the follow types of angles:
Acute, Right, Obtuse, Straight and Reflex

Provided are two files
1. a blank template for students to fill in with their images (Hunting for angles Blank.tns)
2. a completed version which can be used to demonstrate the types of images students could be seeking. (Hunting for angles completed.tns)

Extensions:

Students can be taken outside their classroom into the wider school or they can be set a task of collecting images for homework to bring in to share and compare.
