Perimeter and Area - Calculate Perimeter - Starter

In a Year 5 mathematics lesson, students are tasked with calculating the perimeter of a rectilinear shape. The exercise involves adding the lengths of all the sides to find the total distance around the shape. The diagram provided shows various side lengths such as 12cm, 8cm, 7cm, 4cm, and 3cm, which the students must sum up to determine the perimeter. This activity is designed to enhance their understanding of perimeter and to practice their addition skills. Additionally, students are encouraged to use squared paper to draw two distinct rectilinear shapes, each with an area of 22 squares. After creating their shapes, they are prompted to compare them with a partner to discuss whether the shapes are identical or different, fostering a collaborative learning environment.

Another engaging activity for the students involves the use of coordinates to spell out the name 'Rosie'. The task requires students to write down the coordinates corresponding to each letter of the name using a grid that maps letters to numbers. This exercise not only reinforces their knowledge of coordinate systems but also integrates literacy into the mathematics lesson. By plotting points on the grid, students learn to navigate the x (horizontal) and y (vertical) axes, which are fundamental concepts in geometry. These varied and interactive tasks are designed to strengthen the students' mathematical skills in a way that is both educational and enjoyable.
