* '''Estimated Time'''
* Estimated Time: 40 minutes.
* '''Materials/ Resources needed'''
* Materials/ Resources needed:Laptop, geogebra file, projector and a pointer.
* '''Prerequisites/Instructions, if any'''
* Prerequisites/Instructions, if any:
* '''Multimedia resources'''
# The students should have prior knowledge of plane figures, triangles, vertex, angles and sides of triangles.
* '''Website interactives/ links/ Geogebra Applets'''
# They should know the types of angles and measuring angles.
* '''Process (How to do the activity)'''
# They should know that triangles are classified depending on their side lengths as well as angle measurements.
* '''Developmental Questions (What discussion questions)'''
* Multimedia resources:Laptop
* '''Evaluation (Questions for assessment of the child)'''
* Website interactives/ links/ Geogebra Applets:
* '''Question Corner'''
* Process (How to do the activity):
# Begin a discussion like : “ All triangles have ....” .
# Show them different triangles by moving the vertices.
# Let students discuss what they noticed about these different triangles (e.g. different side lengths).
# The teacher will lead the discussion with the questions: “What did you notice about the length of the sides?”, “Do they all have the same length?”
# Through this discussion help the students develop vocabulary and definitions for the following: equilateral triangle, isosceles triangle, and scalene triangle.
* Developmental Questions (What discussion questions): # What did you notice about the sides of the triangles ?
# How many different side lengths can a triangle have? (hint: all 3 sides equal or 2 sides equal all different )
# What type of a triangle is this ? Why ?
* Evaluation (Questions for assessment of the child):
# # Are the students able to differentiate the traingles based on their side lengths.
* Question Corner:
# What does the term side of a triangle mean ?
# If it is an equilateral triangle, then it has ___ sides that are of the same length.
# If it is an isosceles triangle, then it has ___ sides that are of the same length.
# If it is a scalene triangle, then it has ___ sides that are of the same length
