Activity investigates actual how a blue print represents actual dimensions.
Objectives
Measuring actual dimensions from a blueprint
Estimated Time
45 minutes
Prerequisites/Instructions, prior preparations, if any
- The students should have knowledge about scale drawing.
- They should know about scale factor.
- They should understand that a scaling factor should be maintained as constant throughout the sketches.
- Students should be able to read and understand a scaling factor.
- They should be able to find a scaling factor and create a scale drawing.
- The activity on using standard measuring instruments should be done prior to this activity.
- The students should have been introduced to area, calculations and unit conversions.
Materials/ Resources needed
Non digital: Graph sheets, scale, pencil
Process (How to do the activity)
- In the above blue print each individual unit is 4 feet.
- Explain the meaning of 1 unit.
- Each ceramic tile costs Rs 80 per square foot.

- Developmental Questions
- Along with knowing the length and width of the scale model, what additional information do you need to know ?
- What is the scale factor here.
- Evaluation
- What is 1 unit in the given blue print.
- What does '1 unit = 4 feet mean' ?
- What are the actual dimensions of each room ?
- What all factors do you need to know to estimate the painting costs for each of the rooms.
