We will learn the following types of angles: right angles, acute angles, obtuse angles, straight angles, reflex angles and complete angle.

Objectives

Introduce children to different types of angles

Estimated Time

30 minutes

Prerequisites/Instructions, prior preparations, if any

Prior knowledge of point, lines, angles

Materials/ Resources needed

Digital : Computer, geogebra application, projector.
Non digital : Worksheet and pencil.
Geogebra files : "Types of angles.ggb"

Download this geogebra file from this link.

Process (How to do the activity)

Prior hands on activity (optional – children can use two pieces of thread or sticks to move around a fixed point or two sticks tied with a thread).
Vary the slider to show different angles formed
What is observed with the change in position of the arm
Mention the type of the angle depending on their measurements
How does the change in arm length change the angle measure
Vary the length of the arm to show that angle formed are independent of the arm length
Record the values of arm lengths, values of angles and their types in the worksheet

Sl No.	Segment 1 length	Segment 2 length	Interior angle	Reflex angle	Sum of 2 angles	Type of interior angle

-Brief blurb describing what the activity.  If this has been borrowed from some external web site (for example, a non OER or OER site which had this idea and based on which the activity was developed)
 === Objectives ===
-Content objectives  - what content areas
+Introduce children to different types of angles
-Skill objectives - what specific skills
-Classroom objectives - to demo peer learning, to make a classroom resource, etc -
-All these kinds of objectives need not be there for every activity.  And no need to list them as different headings.  This is only for our reference when we are developing activities.
