DEMO – Lesson/Activity Plans For Mathematics Teachers
Hello Teachers…! Welcome to the mathematics teacher corner of our blog onlinepsa.in. This space is specifically created for teachers who are looking for teaching materials, contents and resources. Below you will find some demo lesson plan for secondary Mathematics classes .i.e. for grade 6 to 10th. These are basically sample lesson plan for a particular day, so, you might not call it as a lesson plan but as an activity plan or micro teaching plan for a duration of 40 minutes. These sample/demo lesson plan might help you with your daily teaching, you can use this lesson plan format and modify it to your suitability and teaching methodology.

GENERAL OBJECTIVE– 
SPECIFIC OBJECTIVE– 
TEACHER– ( SEQUENTIAL LEARNING ACTIVITIES) 
STUDENT EXPECTED RESPONSE– 

After the completion of this lesson student would be able to – Use the concept to find the central tendency of grouped data using the concept of median. Apply the knowledge in day to day life problem solving scenarios. 
After the completion of this lesson student would be able – to form cumulative frequency distribution table of both less than and more than type. To define median class using it to find the median of grouped data. 
Teacher initiates the class by asking simple MLL questions related to “median of ungrouped data” so as to assess the prior knowledge of students. And summarizes it once again.
Teacher declares that today they will try to understand the concept of finding median of previous year mathematics result of class Xth as the grouped data. Teacher shows the result analysis of previous year Class Xth Mathematics and interprets its information. Forms cumulative frequency distribution table of both less than and more than type from the given data. Teacher shows how to define the median class as the class whose cumulative frequency is greater than (and nearest to) n/2. And using it in the formula how to calculate the median. 
Student recalls the idea of concept taught in class IX and responds. Student gets excitedly attentive for the previous year performance data of class Xth students. Student observes carefully and tries to interpret it. Student carefully observes and understands both the less than and more than table. Student understands the way to identify the median class, and the elements given in the formula to find the median.

H.O.T.S QUESTIONS (HIGHER ORDER THINKING SKILL)– 

To analyze previous year performance of class Xth students and finding median as the central tendency of that data. Comparing the value of median and mean of the given data.

How to find median of ungrouped data: 7,3,6,4,2,1,4,3,6,3,2,1,8,9,4,4
What are these abbreviations stand for? l = n = cf = f = h = 
Why there might be some difference in the value mean and median?

After the completion of this lesson student would be able to – Use the concept to find the surface areas and volumes of solids shapes. Apply the knowledge in day to day life problem solving scenarios. 
After the completion of this lesson student would be able – Tell the formulas of total surface area, lateral/curved surface areas and volumes of solid shapes. Apply the concept to Solve problems based on surface areas and volumes of cube, cuboid, cylinder, cone, sphere and hemisphere. 
Teacher initiates the class by asking simple MLL questions based on simple formulas of solid shapes studied” so as to assess the prior knowledge of students. And summarizes it once again.
Teacher declares that today they will be discussing few very important questions from examination point of view. Teacher explains a question related to triangle and its shape forms when one side is to be rotated, using a model. Then, asks to find the volume of the solid shape formed. Twists the question by changing its side of rotation. And then ask to find the volume of the shape formed. Tells them to compare. Corelating topic with physics Teacher explains another question related to density and mass of sphere. 
Student recalls and responds to the question being asked.
Student gets excitedly and gets ready for the important questions to answer them.
Student observes carefully and applies the concept to solve the problem. Student carefully observes the other way and thinks critically about the changing of side of rotation and change of its volume. Corelates the topic with physics concept of mass, volume density and responds to it. 
PREREQUISITE KNOWLEDGE: Students are expected to have the idea of formulas of total surface area, lateral/curved surface areas and volumes of solid shapes.
As the recapitulation strategy teacher can ask students to tell formulas of total surface area, lateral/curved surface areas and volumes of solids shapes to access the prerequisite knowledge of the student. 
BlackBoard Work:
Under achiever students would be called to write the formulas in the blackboard. They will be motivated to solve the problems in the blackboard.

TOPIC– Area of General Quadrilateral 

GENERAL OBJECTIVE– 
SPECIFIC OBJECTIVE– 
TEACHER– 
STUDENT EXPECTED RESPONSE– 

After the completion of this lesson student would be able – To understand what is meant by Triangulation. To find area of a quadrilateral whose diagonals and lengths of the perpendiculars on it is provided. 
After the completion of this lesson student would be able to Understand the concept used to find the area of a general quadrilateral.
Using the concept to solve the problems related to finding areas of different quadrilaterals. 
Teacher initiates the class by asking simple questions related to area and perimeter so as to assess the prior knowledge of students.
Teacher declares that today they will understand how to find the area of general quadrilateral.
Teacher asks students whether a quadrilateral can be divided into triangles. If yes how? Teacher asks students whether anyone knows what this process is known i.e to divide a quadrilateral into two triangles by drawing a diagonal. It is known as Triangulation. As we know area of a triangle= ½ x base x height .this will be used to find the area of the two triangles and then add the both values. SUMMARISATION Triangulation is process of dividing a quadrilateral into two triangles by drawing a diagonal. Area of a quadrilateral= ½ x diagonal length x sum of perpendiculars drawn on it. 
Students recollect the idea of concept taught and responds.
Students get excited for the same.
Students carefully listen to it and answer yes. Student answered by drawing a diagonal in a quadrilateral. Students may or may not answer. .
