Introduction

Introduce and draw the different types of angles: right, acute, obtuse and straight angles. Students can draw and label these in their books. Look for these angles in the classroom.

Activity

Students make angle arms with two strips of paper and a paper fastener (split pins). Students use these angle arms to investigate the angles in the room. Students list five different objects and their respective angles. (E.g. fan blades = obtuse angle).
Challenge students to find at least one object for each type of angle.

Extension: Look at the upper case letters of the alphabet and identify the angles in each letter. (Eg. M= 3 acute angles.)
