COMPLETE DECIMAL SYSTEM
This material can be used from around 5 years onwards and offers the child many possibilities. The main goal is to make the decimal system understandable by working with physical objects and symbols. With this material the child can compose big numbers and apply the four arithmetic operations to them, proceeding in a clear and conscious way from a concrete dimension to abstraction.
