Subject: Mathematics

Topic: Mensuration

Learning objectives:

Students will  be  able  to calculate

Surface area of circle,square, rectangle, rhombus, trapezium.

Surface area of cube and cuboid.

Surface area of a right circular cylinder

Volume of cuboid.

Volume of cylindercylinde

Understand how to derive formulae to calculate the area of Trapezium and rhombus. 

Know the properties of polygons. 

Derive the formulae to compute  area of polygons. 

Derive the formula to find surface area of solidshapes (Cube, Cuboid and cylinder) 

Difference between volume and capacity. 

Teaching Methodology

A) Teaching aids: flash cards, chart, solid shapes

b) Teaching Strategy:

Student will be asking oral questions about 1.Basic knowledge of triangles and circles.2.Knowledge of square,rectangle, parallelograms and solid figures.3.Knowledge of calculating perimeter and area of square and rectangles. 4. properties, perimeter and area of different shapes like circle, square and rectangle. 5. Properties of 2D shapes and their formulae. 6. Knowledge about the faces, vertices and edges of cube and cuboid. 7. areClassification of polygons; special polygons, plane shapes & solid shapes Formula for area of plane shapes like square, rectangle, triangle and circles. 

Assignment: Students will be asked to write NCERT questions as home assignment.

Subject enrichment activities: The students will do the miscellaneous exercise in their note book. 

Learning outcomes: Students will develop the ability to understand

1.Total surface area and curved surface area of solid shapes.2.Volume of solid shapes to1.Find the area and perimeter of base of square, rectangle, parallelogram, triangle and circle. 3. Identifysolid shapes and their properties.4. will be able to deduce the formulae to find area and volume of different shapes (plane & solid shapes) 5.  Will be able to describe what plane shapes, polygons & solid shapes are and their types with examples. 6.  Will be able to solve the questions related to area of polygons, special polygons, solid shapes & plane shapes.
