| + | # Measurements – length, angles. Point has no dimension. Line segment has a finite length; rotating lines to make angles. Measuring angles. (2 periods). |
| + | # 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? |
| + | # Parallel lines (emphasise uniform perpendicular distance) (2 periods) |
| + | # 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. |
| + | # Through observing angles, observe properties of lines (eg, when angle pairs are observed what can you say about the lines forming them) |
| + | # Intersecting lines (3 lines cover an area called a triangle; 4 lines cover a quadrilateral) |
