SMASE – ASEI PDSI METHOD
TOPIC: Lines of Symmetry and Angles
Lesson One – Lines of Symmetry I – Triangles
Lesson Two – Lines of Symmetry II – Quadrilateral
Lesson Three – Horizontal and Vertical Lines
Lesson Four – Angles
Lesson Five – Cardinal Points
TIME – 40 Minutes each.
By the end of the lesson, pupils should be able to:
1. identify symmetrical plane shapes.
2. locate line(s) of symmetry of objects in the school and homes.
3. distinguish between horizontal and vertical lines.
4. indicate the four cardinal points and relate the setting and rising of the sun on the cardinal points of the East and West.
If you can reflect (or flip) a figure over a line and the figure appears unchanged, then the figure has reflection symmetry or line symmetry. The line that you reflect over is called the line of symmetry. A line of symmetry divides a figure into two mirror – image halves. Angles are when two or more lines meet or intersect. The space between two lines is called an angle. Cardinal points are direction – North, South, East and West
In this lesson, the pupils will identify lines of symmetry of any shapes and also identify different types of angles and locations of places.
The teacher will teach the lesson with the aid of:
Chart and model of the four cardinal points.
Lines of symmetry divide shapes into two similar shapes. Angles are the space between two intersect lines.
