„Relationships have been found between number-based parent-child activities (such as naming digits, counting, and discussing number values) and the child’s mathematics ability. Similarly, numerical fluency (the ability to perform mathematics problems quickly and efficiently) and math knowledge have been shown to be enhanced through a young child’s home-based exposure to formal teaching of number skills and informal numeracy activities (such as number games and everyday applications).“
