Paper Folding Activity- Lines and Angles

Process (How to do the activity)

 * 1) Measurements – length, angles. Point has no dimension.  Line segment has a finite length; rotating lines to make angles.  Measuring angles.  (2 periods).
 * 2) Line by itself...making a line; part of a line (on a playground, graph sheet, geogebra).  Is there a thing called distance between two lines?
 * 3) Parallel lines (emphasise uniform perpendicular distance) (2 periods)
 * 4) Pairs of angles (rotation, complementary and supplementary angles as geometric constructs, why Z-angles and F-angles are equal) -through have children put angles together to make 90, 180 degrees (3 periods).  Introduce acute and obtuse.
 * 5) Through observing angles, observe properties of lines (eg, when angle pairs are observed what can you say about the lines forming them)
 * 6) Intersecting lines (3 lines cover an area called a triangle; 4 lines cover a quadrilateral)
