This activity explores representation of actual distances on paper using proportional distances.
Objectives
- Representing actual distances on paper using proportional distances.
- Understanding meaning of scale
Estimated Time
1 hour
Prerequisites/Instructions, prior preparations, if any
- Skill of measuring and tabulating accurately.
- Knowledge of ratio and proportions.
Materials/ Resources needed
Non digital : Scale, pencil, graph paper.
Process (How to do the activity)
- This activity can be done in groups by grouping 3 students in each.
- The students should measure distances of library, dinning hall, principal's room, entrance gate, playground etc from their class room using a measuring tape in metres.
- The teacher can mark reference points for each and explain to the students.
- The students should accurately measure and note down.
- After coming to the classroom let the teacher tabulate all distances on the blackboard.
- Next ask the students to represent their observation of distances by drawing their school model on paper.
- Ask them how will they go about it so that the distances are represented proportionately.
- The teacher can then elicit from the students that a proper equivalent unit has to be used for the purpose.
- After this activity she can spell out the term scale and discuss about the blue print of a house, mapping distances, atlas maps, model constructions and so on.
- This activity can be done to introduce the students to the concept of scale drawing.
- Developmental Questions
- What did you measure ?
- What measuring instrument did you select ? Why ?
- What was your reading ?
- which unit do you use ?
- Evaluation
- Were the students able to comprehend which measuring instrument should be used for particular items ?
- Were they taking measurements accurately ?
- Were they able to document their observations appropriately in a tabular form ?
- Question Corner
- Discuss the applications of scale drawing ?
- What is a scale factor ?
