=Activity - Scale Drawing=

Estimated Time
1 hour

Materials/ Resources needed

 * 1) Scale, pencil, graph paper.

Prerequisites/Instructions, if any

 * 1) Skill of measuring and tabulating accurately.
 * 2) Knowledge of ratio and proportions.

Process

 * 1) This activity can be done in groups by grouping 3 students in each.
 * 2) 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.
