Jumbo Regular & Irregular Shapes - Pk12

Translucent colour geometric shapes in 6 bright colours, designed to offer foundation knowledge of the relationship between regular and irregular shapes. The inner and outer puzzle pieces match, by their colour and their attributes, e.g. the orange pentagons each have 5 sides; the irregular shape fits inside the regular shape to reinforce the understanding that both shapes are still pentagons, even though they look different. The set can be used to demonstrate that regular shapes have equal angles and sides; irregular shapes can have angles and sides of any value. The mathematical extension of this process is that the sum of the interior angles of a regular shape will always be equal to the sum of the interior angles of the corresponding irregular shape.
