Area Wall Chart

The Area Wall Chart is a comprehensive educational resource designed to help intermediate mathematics learners understand how to calculate the area of a wide variety of two dimensional shapes. Through clear diagrams, colour coded illustrations, and step by step worked examples, this wall chart explains the formulas used to find the area of common geometric figures while showing how those formulas are derived. It is an excellent classroom display, homeschooling aid, or mathematics poster that supports visual learning and reinforces key geometry concepts.

The chart begins by explaining the difference between perimeter and area using a rectangle. It demonstrates how perimeter measures the distance around a shape while area measures the surface inside it. Learners are guided through calculating the area of rectangles using the formula length × breadth, with both whole number and decimal examples to develop confidence with practical calculations.

Additional sections explore the area of parallelograms, showing how rearranging a rectangle produces the same area formula of base × height. The triangle section explains why a triangle's area is half the area of a rectangle or parallelogram with the same base and height, including examples where the height must be extended outside the triangle. The chart also introduces the area formulas for trapeziums, rhombuses, and kites, using labelled diagrams that clearly illustrate diagonals, parallel sides, and height measurements.

The final section covers the area of a circle, explaining the formula πr² with a fully worked example using the radius of a circle. Throughout the chart, colourful illustrations, mathematical notation, and practical examples make complex geometry concepts easier to understand. This durable educational poster is ideal for schools, tutoring centres, and home learning environments, helping students develop a solid understanding of area calculations across multiple geometric shapes.
