===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 the concept of angle
* To introduce measure of angles
* Methods of measuring angles
===Estimated Time===
30 minutes
===Prerequisites/Instructions, prior preparations, if any===
* Digital : Computer, geogebra application, projector.
* Non digital : Worksheet and pencil.
* Geogebra files : "[https://ggbm.at/chrquf9j Introduction to angle formation]”
{{Geogebra|chrquf9j}}
===Materials/ Resources needed===
* Digital : Computer, geogebra application, projector.
* Non digital : Worksheet and pencil.
* Geogebra files : "Introduction to angle formation”
===Process (How to do the activity)===
Prior hands on activity (optional – children can use two pieces of thread to move around a fixed point or two sticks tied with a thread).
'''-Formation of angle'''
Use the file to demonstrate formation of angle
Ask how segments rotation changes angle
Ask how many angles are formed
'''-Measure angles'''
How do you measure this angle
Measure both angles as the children say
Ask if there is any difference in the angle measures
Mention the convention of clockwise/anticlockwise measurement
Mention reflex/exterior angle
Is there a relation between the two angles measured
'''-Angle measure independent of segment length'''
Does the angle depend on the segment length – drag the line segments to show.
'''Evaluation at the end of the activity'''
* What are the different types of angles?
* When two segments are joined at a point how many angles are formed?
* What is the measure of the total angle formed at a point is?
* What is the convention used to measure angles?
