Properties of shape - 2D shapes​ - Presentation

In a comprehensive lesson on the properties of 2D shapes, students are encouraged to engage with the fundamental aspects of geometry through a variety of activities. The lesson starts with a prompt asking students to name and describe various 2D shapes, focusing on their sides, corners, angles, and symmetry. This sets the stage for a deeper exploration into the world of two-dimensional figures. The first activity challenges students to describe a specific quadrilateral, prompting them to count its angles, identify the types of angles it contains (right, obtuse, acute), and determine the number of lines of symmetry it has. This activity is designed to enhance students' fluency in recognising shape properties and to develop their reasoning skills.

Subsequent activities involve identifying shapes based on given properties, such as the number of angles and lines of symmetry, and drawing shapes with certain characteristics, like a triangle with two equal sides or a square with sides measuring 2 cm. Students are also tasked with reasoning exercises, where they must infer and draw a shape described by its properties, such as having two pairs of parallel sides with unequal lengths. The lesson encourages collaborative learning through discussion and partner activities, where students describe shapes to one another and attempt to identify them based on the descriptions. The aim is to deepen their understanding of 2D shapes and to equip them with the ability to spot and describe the various properties that define these geometric figures.
