Teaching Outlines
Concept #1. What is Mensuration ?
Learning objectives
- The students learn that mensuration is the branch of Mathematics dealing with measurement of angles, length, area, and volume.
- They should understand the need for measuring objects.
- They should have a clear distinction of different measuring/calculating parameters
- They should understand the characteristics of different figures.
- The length of the total boundary of a figure is called its perimeter. The Metric unit of perimeter is same as the unit of length - Metre.
- The perimeter of 2D geometrical figures like quadrilaterals can be obtained by calculating the sum of all the sides of the figure.
- The amount of surface covered by an object is called it area. The Metric unit of area is square metre.
- The capacity of an object to hold is called its volume.
- Develop an appreciation towards derivation of formula for calculations.
- They should develop the ability to calculate the area, perimeter, volume or side of many different figures.

Concept #3. Standard units of measurements
Learning objectives
- They should understand that there is no natural unit for the measurement of surfaces. It is necessary to fix upon an artificial unit and that , that artificial unit is a square. To find the area of a surface is to find how many times this measuring unit can be applied to or is contained times in the given figure.
- It is essential for students to have an understanding of the units used to measure .
