Content for third class

The child should be enabled to

  • Identify, describe and classify vertical, horizontal and parallel lines?
    Discuss and describe lines in the environment?
    Draw and label lines.
    Use geostrips to construct vertical and horizontal lines.
  • Recognise an angle in terms of a rotation?
    Form angles by opening books and doors, by rotating clock hands and geostrip arms, by physically turning (clockwise/anti-clockwise), or on computer.
  • Classify angles as greater than, less than or equal to a right angle.
    Construct and use a right-angle measure to identify right angles in the environment and in 2-D and 3-D shapes.
    Classify and record angles as >, < or = to a right angle.
  • Solve problems involving lines and angles.

Content for fourth class

The child should be enabled to

  • Identify, describe and classify oblique and perpendicular lines. Use straws to construct oblique and perpendicular lines and diagonals in a square?
  • Draw, discuss and describe intersecting lines and their angles such as perpendicular and oblique lines, acute, obtuse and right angles?
  • Classify angles as greater than, less than or equal to a right angle
  • Solve problems involving lines and angles.
