Geometry Shape - Recognise and name 2D shapes - Worksheet

The lesson plan for Year 3, entitled "Recognise and Name 2-D Shapes," sets out to help students identify and name common two-dimensional shapes, such as rectangles (including squares), circles, and triangles. The resources required for this lesson include differentiated worksheets, teaching slides, and a selection of 3D shapes through which students can observe 2D shapes. The children are expected to understand that 2D shapes are flat, as opposed to the three-dimensional objects they may see in their everyday environment. Key vocabulary for the lesson includes terms like '2-D', 'three-dimensional', 'orientation', and names of various shapes and geometric properties such as 'cube', 'cuboid', 'cylinder', 'pyramid', 'cone', 'sphere', 'face', and 'surface'.

During the lesson, children will engage in activities that require them to circle or tick the correct 2D shapes from a given set, enhancing their fluency and precision in shape recognition. They will use the surfaces of 3D shapes as stencils to create 2D shapes, reinforcing their understanding of flat shapes. In the reasoning and problem-solving segment, students will be challenged to identify partially hidden 2D shapes and explore how many ways these can be completed using straight lines. This will be differentiated for various levels of understanding, from recognising simple shapes to investigating more complex or hidden ones. The lesson will prompt critical thinking through key questions about the properties of shapes and their occurrence in the classroom environment.
