Numbala is more than just a toy for children; it's a cognitive training tool designed to teach them math. When we first learn numbers, our minds create what's called a mental number line. This is how the human mind organizes numbers in space and their relationship to one another. It's the foundation of all math, and it can be taught! When you move your finger across Numbala's control panel, your brain creates an association between the number and its position in space.
