In grade 1, students are introduced to the basic concepts of shapes, including understanding sides and corners (vertices).

- Sides:

Definition: Sides are the straight lines that make up the boundary of a shape.

Explanation: Imagine walking along the edge of a shape. The path you follow is made up of the sides of the shape.

Example: In a square, there are four equal sides, and in a triangle, there are three sides. - Corners (Vertices):

Definition: Corners, also called vertices, are the points where the sides meet.

Explanation: Corners are like the meeting points of the sides. They are where you change direction as you walk along the edges.

Example: In a square, there are four corners where the sides meet. In a triangle, there are three corners.

Examples for Grade 1:

Square:

Sides: Four equal straight sides.

Corners: Four square corners where the sides meet.

Triangle:

Sides: Three straight sides.

Corners: Three corners where the sides meet.

Circle:

Sides: No straight sides.

Corners: No corners (considered round).

Shape Hunt:

Have students identify and count sides and corners in everyday objects around the classroom.
Drawing Shapes:

Ask students to draw different shapes and label the sides and corners.

In grade 1, the emphasis is on introducing these basic concepts in a simple and concrete way. Engaging activities and visual aids help make the learning experience enjoyable and effective. As students progress, they’ll build on these foundational concepts in later grades.

Have a look at this video, if you need to review how to identify shapes by the number of sides and corners.
