This lesson plan is about teaching pyramids in mathematics. It will analyze the key attributes of pyramids, including that they have one base and more than one triangular lateral face. The names of different pyramids depend on the shape of their base. Examples of positive and negative pyramids will be presented, and students will attempt to define the concept of a pyramid based on the examples. The lesson aims to teach pyramids in an interactive way where the teacher presents examples and students identify whether they are essential or non-essential to defining a pyramid.

ANALYSIS OF THE CONCEPT
1. Name : pyramids
2. Attributes
1)Essential attributes :1)pyramids have one base and more than one
lateral faces .
2)Lateral faces are always triangular shape and
theese tringles are isosceles.
3)The names of the pyramids are depending on
their shape of the base.
2)Non-essential attributes : The shapes which are 2 diamensional

2.  Examples
1)positive examples :

3. 2)Negative examples :
4) Definition: A Pyramid is a polyhedron that has a base, which can be any
polygon, and three or more triangular faces that meet at a point.

PHASE 1 : Presentation of the data and
identification of the concept
Teacher : Today we are going to study in a
different way. I will give you some examples
which are essential and non-essential to the
concept in my mind.You have to find out what
is that concept,from the examples given and
also defines the concept.
Teacher:
This is an essential example for the concept in
my mind.
Student : The base is square , lateral faces are
triangles and also it is a 3 dimensional shape.
Teacher :
This is a non-essential example for my concept
Orientation of the process
Teacher presents the first positive
example.
Students forms the first hypothesis.
Teacher presents the negative example.
