Perimeter, Area and Volume - Area and Perimeter - Worksheet

The lesson on "Area and Perimeter" aims to equip children with the ability to recognise and utilise formulae for calculating the area and volume of shapes, specifically parallelograms and triangles. To facilitate learning, resources such as differentiated sheets and teaching slides are provided, along with key vocabulary terms including 'shape', 'area', 'perimeter', and 'formula'. Students are expected to calculate the area and perimeter of rectilinear shapes, developing a conceptual understanding of these formulae through practical exercises such as counting squares. One of the lesson's objectives is to demonstrate that shapes with identical areas can have varying perimeters, and students are tasked with calculating missing values, such as a side or area, which may require unit conversions between millimetres and centimetres.

Further into the worksheet, reasoning and problem-solving skills are honed as students work on examples like Zach's rectangle, where they observe the effects of increasing the length and width on the area. The exercises encourage children to explore patterns and question whether these patterns hold true across different examples. The answers section provides solutions and explanations for the tasks, including the conversion of measurements and the calculation of missing values. This comprehensive approach ensures that students not only learn the formulae for area and perimeter but also understand the underlying mathematical principles and can apply them in various contexts.
