Jumbo Regular & Irregular Shapes

Jumbo Regular & Irregular Shapes

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.

• An ideal resource for learning about shape names and their properties, as well as mathematical terms such as side, point, curve, inside, outside, flat, 2D, solid, 3D, angle and symmetry. Can also be used for shape and colour recognition, colour mixing, as templates for drawing and colouring, as a shape matching puzzle and for investigating on a light panel.

• The shapes are made from 3mm acrylic and each one comes with a 2.5mm hole at the top balance point so they can be strung up against a window or outdoors to create colourful shape shadows.

• Size of circle: 150mm dia.
