===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
What kinds of questions you can ask for that activity
* 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 are the student follow-up activities/ questions you can give?
* 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
