Numicon is an approach utilising these skills:
Communicating mathematically
Exploring relationships

Numicon follows the principles of learning described by Bruner where children learn best with three representations used together to create meaning and conceptual understanding. 

By using concrete structures more than pictures and abstract representations, children are able to access number knowledge and the relationships of number and all the strands of mathematics easily.

The components of the Numicon Approach are the Teaching Resources and the Classroom Resources
