Perimeter and Area - Assessment (2)

The Year 5 assessment on Area and Perimeter presents a series of questions designed to evaluate a student's understanding of these fundamental mathematical concepts. Students are tasked with estimating the area of a shape drawn on a centimetre square grid, which is a practical application of their spatial awareness and estimation skills. They are also asked to calculate the exact perimeter of the same shape, requiring them to apply their knowledge of adding lengths of sides. Additionally, the assessment includes a question where students must correct a misconception: Rosie incorrectly asserts that two rectangles with the same area must have the same perimeter. Students are expected to explain why this statement is incorrect, demonstrating their understanding that area and perimeter are related yet distinct properties of shapes.

Further challenges in the assessment involve finding missing side lengths and completing calculations to determine the perimeter of composite shapes. One real-world application question asks how many tins of paint Malachi would need to cover a wall of a given size, with each tin's coverage area specified. This encourages students to apply their area calculation skills to practical scenarios. The assessment also invites students to express their confidence level with the topic, providing insight into their self-assessment skills. Advanced questions include drawing shapes with specific area and perimeter requirements, working with equilateral triangles and regular hexagons, and combining shapes to find new perimeters—tasks that promote higher-order thinking and a deeper understanding of geometric properties.
