Plane Figures: Exercise: Find Divergent Lines in the Environment

Age
6-9.

Presentation

 * 1) Position one stick horizontally on the board.
 * 2) Use two different guide sticks to position the second stick.
 * 3) Fix the second stick and set the guide sticks aside.
 * 4) Place the two happy children at the wide end.
 * 5) As these two go along, they become closer and closer and happier and happier, knowing that in the end they will meet.
 * 6) Replace the figures with one-way arrows.
 * 7) These lines go only in one direction - toward each other.
 * 8) These are convergent lines. (convergent: Latin con- together, and vergera - to incline)
 * 9) These lines come from two different points toward each other to one point.
 * 10) Love stories in geometry, like those in real life can change.
 * 11) Place extra sticks at the narrow end to see how these line continue in their one direction.
 * 12) What happens? After the point of convergency, these two lines become divergent.

Variation
