Topology

Briefcase with geometric bodies 14 and 15 strips to represent up to 50 different images. It allows developing spatial perception and knowledge of the various geometric bodies through observation and manipulation.
This material encourages the development of logical-mathematical thinking and spatial structuring by means of
handling activities and reproducing the model-photographs. Numerous objectives can be achieved by using this material:
Establishing a relationship between the two-dimensional example and the real three-dimensional space.
Developing the perception of regions and limits in space
Facilitating the learning of spatial concepts: inside-outside, interior-exterior, in front-behind, on top-underneath, near far,
together-separate, one side-the other side, left-right, around, between, in the middle, etc.
Encouraging initiation of spatial relationships between objects: proximity-distance, horizontal symmetry, vertical
symmetry, vertical, etc.
Knowledge of particular properties of the objects or figures in terms of their: shape (square, triangular, rectangular,
pentagonal, hexagonal), size (large, small), volume (cube, prism, pyramid, sphere, cylinder, cone), colour (red, blue,
yellow, green), surface and line (open, closed)
Undertaking classifications by shape and/or colour.
