Name of the activity

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

Introduce children to concept of adjacent angles

Estimated Time

20 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 : Adjacent angles.ggb

Download this geogebra file from this link.

Process (How to do the activity)

Prior hands on activity (optional – children can use news paper strips to form angles and place them together and notice the resulting angle formed).
Change the measure of the angles – angle1 and angle 2 using the slider
If the two angles are place next to each other , what will be formed
Use the slider to place the angles next to each other
What is the resulting angle formed due to the two angles
What is the measure of the angle formed when the two are placed to each other
Is there any other way to make the two angles adjacent
Record the values of the two angles and their sum in the worksheet

Sl No.	Angle ABC	Angle DEF	Angle ABC + Angle DEF	Angle O	Is the sum of two angles greater than Angle O
.
