| + | ===Objectives=== |
| + | ===Estimated Time=== |
| + | 15 minutes. |
| + | |
| + | ===Prerequisites/Instructions, prior preparations, if any=== |
| + | #Cube and its properties should have been done. |
| + | #Formula to find the area of a square. |
| + | ===Materials/ Resources needed=== |
| + | Laptop, geogebra file, projector and a pointer. |
| + | |
| + | ===Process (How to do the activity)=== |
| + | #Project the geogebra file that would enable the students to visualise an opened cube. |
| + | #Ask the following questions. |
| + | *Developmental Questions: |
| + | #What is the formula to find the area of a square ? |
| + | #What does the term 'area' mean ? |
| + | #What is the meaning of total surface area ? |
| + | #How many squares are there totally in a cube ? |
| + | #Therefore what is the total surface area of a cube.? |
| + | #What does the term 'lateral' mean ? |
| + | #What is lateral surface area ? |
| + | #How many squares are there in a lateral surface of a cube ? |
| + | #Hence what is the formula to find the lateral surface area of a cube ? |
| + | #What does the term 'volume'mean ? |
| + | #What is the formula for volume in general? |
| + | #What is the formula for volume of cube ? |
| + | *Evaluation |
| + | #Were the students able to comprehend the difference between area and volume ? |
| + | #Were they able to understand the distinction between the lateral surface area and total surface area ? |
| + | *Question Corner: |
| + | #What is the formula to find the area for a cuboid cantainer with no lid and with lid ? |
| + | #Give some examples of objects which are cuboidal in shape. |
