## 1. Key Concepts (Topic)

### 1.1. Area: Space in a plane figure (2D), bounded by boundary

### 1.2. Relationship betwen area and dimensions,

1.2.1. bigger dimensions give bigger area?

1.2.2. Product of dimension(length and breadth) gives area

1.2.3. Units squares, count number of squares

1.2.4. Units of measurement, units squares, cm^2, m^2

### 1.3. Composite figures

1.3.1. Difficulties

1.3.1.1. Boundaries are not clear, dimensions not clearly shown. Need spatial visualisation

1.3.1.2. Many possible ways to find the area, partition the figures into smaller shapes, removal of a smaller shape from the bigger shape

1.3.1.3. Prior knowledge on properties of rectangles and squares needed

1.3.2. Want students to be able to determine the easiest, most efficient method to find the area
