Teaching Outlines

Concept # 1 - Connection between algebra and geometry through graphs of lines and curves

Learning objectives

• connection between algebra and geometry through graphs of lines and curves.
• Enabling geometric problems to be solved algebraically
• Geometrically visualising algebra
• introducing to the Cartesian coordinate plane
• plotting points on the plane
• reading coordinates for a point from a graph

Notes for teachers

• A plane is a flat surface which can be extended in any directions.
• coordinate geometry gives us a way to describe a point on the plane exactly by two numbers.

Activities

1. Familiarising to Cartesian Coordinate system - Activity No 1
2. Idea of introducing to coordinates - Activity No2
