Geometry Shape - Sort 2D shapes - Presentation

In Lesson 4 of a geometry series, students engage with the topic of sorting 2D shapes. The lesson aims to develop students' understanding of shape properties by having them sort and group a variety of simple 2D shapes. The class begins with a discussion where students are encouraged to identify shapes based on given properties and to describe different shapes to their partners. For example, a shape may be described as having six corners and six sides, prompting students to think about which shape fits this description and to compare it with other shapes they know.

Following the initial discussion, the students participate in a series of activities designed to deepen their understanding of shape characteristics. Activity 1 challenges them to identify the odd one out within different groups of shapes and to compare and contrast shapes to spot similarities and differences. In Activity 2, they are asked to label groups of shapes based on how they have been sorted, such as by squares and circles, and to describe the reasoning behind the groupings. Activity 3 further develops their reasoning skills as they create their own groups of triangles, rectangles, squares, and circles, and have a partner label them. Throughout these activities, students explore various ways to categorize shapes, including by colour, name, and the number of sides. The lesson concludes with independent work where students cut out shapes and sort them into categories, reinforcing the concepts discussed and allowing them to demonstrate their understanding of 2D shapes and their properties.
