                     Challenge Question                                                                     Critical Thinking

                 On a map, Town A is exactly 5 cm north of Town B. The map’s scale is 1 cm = 10 km.
                 A river runs east to west exactly between the two towns. What is the actual distance
                 from Town A to the river?

                 Take  a  chart  paper  and  draw  a  route  map  from  your  school  to  your  house
                 by using different keys (symbols).


              2d Floor MapS aNd 3d deep drawiNgS

              2D floor plans show the basic outline of a building including walls, doorways, windows and

              entrances.  It  is  a  flat  drawing  or  a  floor  map  that  shows  the  layout  of  every  part  of  the
              building very clearly. Before construction, the building is described using the floor map. A
              floor map creates a key to illustrate how the available space should be used.
              Look at the floor map of Bharat’s house.

              It  shows  the  planning  of  the  space  available  and  the
              windows and doors in the walls of the house. The floor
              map  does  not  give  a  complete  picture  of  the  house  or
              show what it would look like after it is built.

              The picture alongside shows the deep drawing or the 3D
              model of Bharat’s house. A deep drawing is a 3D drawing
              showing  the  length,  width  and  height  of  a  house  or  a
              building.  It  is  drawn  on  the  basis  of  the  floor  map.  The
              deep drawing matches the specifications of the floor map.
