*Estimated Time : 1 hour
*Materials/ Resources needed :
# Scale, pencil, graph paper.
*Prerequisites/Instructions, if any
# Skill of measuring and tabulating accurately.
# Knowledge of ratio and proportions.
*Multimedia resources
*Website interactives/ links/ / Geogebra Applets
*Process:
# 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 ?
