*Process:
# Let the students measure different ingredients using suitable measuring instruments and record their observations in a tabular form.
# This activity can be done in groups by grouping 3 students in each group.
# 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.
# Ater this activity she can spell out the term scale and discuss about the blue print of ahouse, mapping, model constructions and so on.
