# Identify common 2D shapes (circle, square, triangle, rectangle) and 3D shapes (sphere, cube, cone, cylinder) in various everyday objects and surroundings.
# Identify common 2D shapes (circle, square, triangle, rectangle) and 3D shapes (sphere, cube, cone, cylinder) in various everyday objects and surroundings.
# Differentiate between different shapes based on their characteristics (e.g., number of sides, corners, faces, edges).
# Differentiate between different shapes (Classify and sort) based on their characteristics/attributes (e.g., number of sides, corners, faces, edges).
# Learn the appropriate terminology to describe various attributes of shapes, such as sides, vertices (corners), edges, and faces. This helps them communicate and compare shapes effectively.

'''Misconceptions about shapes:'''
# Misidentifying Shapes: Students might confuse similar-looking shapes, such as mistaking a rhombus for a square or an oval for a circle.
# Equating Sides and Vertices: Children might mistakenly believe that the number of sides is the same as the number of vertices. For example, thinking a square has five vertices because it has four sides and one in the centre
# Miscounting Sides: Counting the boundary of shapes rather than the sides. For instance, counting the curved boundary of a crescent shape as two separate sides
# Overlooking Faces: Not correctly counting the number of faces on a 3D shape. For example, mistaking a triangular prism for a cylinder because they both have circular bases.
# Ignoring Edges and Vertices: Focusing solely on the faces and neglecting to recognize the importance of edges and vertices in defining 3D shapes.
# Misinterpreting Dimensions: Misunderstanding the relationship between length, width, and height in different shapes. For instance, assuming that a cube and a rectangular prism are the same shape because they both have six faces.
# Flat Sides on 3D shapes: Believing that the sides of 3D shapes must always be flat, which can lead to confusion when dealing with curved surfaces like spheres..
