By the end of this unit of work you should be able to do the following:
- Identify, name, measure and draw six different types of angles (acute, right, obtuse, straight, reflex and revolutions)
- Identify, name, measure and draw six types of triangles (acute, right, obtuse, equilateral, isoceles and scalene)
- Identify and name six different quarilaterals (square, rectangle, rhombus, parallelogram, trapezium and kite)
- Identify and draw perpendicular and parallel lines
- Identify and calculate vertically opposite, alternate, corresponding, complementary, supplementary and co-interior angles.
- Calculate missing angles in triangles and quadrilaterals.
- Accurately draw regular polygons and calculate angles in regular polygons.
Each of the following activities matches with specific learning outcomes.
Acute and Obtuse angles – Guess the random angle
Measuring Angles – What’s my Angle?
Naming and measuring angles – Kidport Measuring Angles
Vertically opposite, corresponding and alternate angles – Exploring relationships of Angles
Types of triangles – sort into Venn diagrams – Sorting Triangles
Angles in a triangle add to 180 degrees – Exploring Angles: Resize a triangle
Calculate angles using opposite, complementary and supplementary angles – Exploring triangles.
