2. Properties of Squares and Rectangles (5 - 6 minutes):

   • The teacher will introduce squares and rectangles as quadrilaterals, four-sided polygons.

   • The teacher will explain that squares and rectangles have four right angles, but squares have all sides equal in length, while rectangles have two pairs of equal sides.

   • The teacher will discuss the concept of 'diagonal' and how it relates to squares and rectangles, using a square paper or a rectangle-shaped whiteboard.

   • The teacher will then provide examples from real life where squares and rectangles are used, like in the shape of a book, a smartphone, or a window.

3. Properties of Triangles (5 - 6 minutes):

   • The teacher will introduce triangles as three-sided polygons.

   • The teacher will explain that triangles can be classified based on the measures of their angles and the lengths of their sides.

   • The teacher will elaborate on the different types of triangles, such as equilateral, isosceles, and scalene, and how each type has unique properties.

   • The teacher will provide examples of where triangles can be found in the real world, like in the shape of a slice of pizza, a traffic sign, or a roof.

4. Properties of Other Shapes (3 - 4 minutes):

   • The teacher will briefly highlight the properties of other shapes like pentagons, hexagons, and octagons, and mention that like the shapes previously discussed, these shapes also have their unique properties and can be found in the real world.

   • The teacher will provide examples of where these shapes can be found, like in the shape of a stop sign (octagon), a honeycomb (hexagon), or a home plate in baseball (pentagon).

In all these subtopics, the teacher will encourage students to participate actively by asking questions, identifying the shapes and properties on the teacher's visual aids, and discussing the shapes they have seen in their environment. This interactive approach will not only make the learning process more engaging but will also help the teacher assess the students' understanding of the topic.

Feedback (8 - 10 minutes)
