The Science: Dots & Numbers Game

Symbolic-nonsymbolic number mapping refers to the ability to associate numerical symbols (e.g., "3", "7") with their corresponding nonsymbolic quantities (e.g., *** or *******). This skill is essential in the development of mathematical abilities, as it forms a foundational understanding of what numerical symbols actually represent

Understanding that the symbol "3" corresponds to a group of three items (***), for example, helps children grasp the meaning of numbers, rather than just memorizing them.

This promotes a deeper understanding of mathematical concepts and allows for the understanding of numerical operations.

For instance, understanding that "3" (symbolic) and three apples (nonsymbolic) are the same quantity aids in learning addition, subtraction, multiplication, and division.

Mixed Dots & Numbers & The Brain

The left angular gyrus in the brain's parietal lobe is key to symbolic processing and numerical cognition. It processes numerical symbols, converting them into associated quantities.

It's especially active during tasks involving symbolic numerical information, like arithmetic operations.

It also contributes to our understanding of the "mental number line", a mental spatial representation of numbers, helping us relate numerical symbols to their relative quantities.
