A system and method for teaching basic mathematical operations and facts; and more particularly it is an apparatus for development of accurate conceptual models for small children in learning certain math facts for the first time. The present invention takes into account that a true conceptual model must consistently and accurately reflect the target system and consider the characteristics of the children learners. In this invention, every digit of any number gets a familiar yet consistent name; that name can be weaved into story and rhyme throughout the learning process in both the math questions and in the math answers. The consistent "name for a digit" advancement over the prior art is better because it creates a conceptual model to which children can indeed relate. Digit consistency throughout the system, series, or television program, helps teachers create relevant meaningful application activities or associative modus operandi.
