E1.4 Create and interpret simple maps of familiar places.
Skill: Creating Simple Maps
Create a map using a simple grid to show where one object is in relation to another and to determine distances and paths.
Skill: Interpreting Simple Cards
Terms such as above, below, left, right, behind and in front make it easier to indicate the location of one object in relation to another.
A grid adds structure to a map. It helps to show where one object is in relation to another and to determine distances and paths. The location of objects on a grid corresponds to a real or virtual grid overlaid on a corresponding three-dimensional space.
Sometimes a location on a grid is defined by the intersection of two lines, which gives a precise indication of that location. Sometimes a location on a grid is defined by the space or region between lines, which describes it less precisely. It is important to know which of the two approaches is used.
Adding letters or numbers to a grid allows locations to be described more easily and accurately.

Knowledge: Simple Maps
A simple map can be:
- a concrete map of a classroom on which the furniture is represented by blocks placed in such a way as to reproduce the layout of the classroom;
- a sketch showing the layout of a classroom;
- a grid which is superimposed on an image or a photo where one can determine the position of the objects located at the intersections of the lines.
A simple map represents a three-dimensional space using a two-dimensional depiction that shows the location of objects in relation to each other. A map provides an aerial view of a location.
