Recent findings from the Kids Activity and Learning Study complement North Carolina's multidimensional approach to promoting school readiness by emphasizing the integrated nature of motor and cognitive development in early childhood. Children whose motor skills improved the most over the course of an academic year also tended to demonstrate the biggest gains in executive function and numeracy skills. Children who participated in adaptive, group-based motor skill activities demonstrated gains in motor competence, executive function, and numeracy skills. Incorporating motor activities into established classroom practices has the potential to facilitate multiple aspects of children's development and promote school readiness. The brief includes specific recommendations for early childhood educators.
