Visuo-spatial training is considered a promising approach to provide young children with a sound foundation for later mathematical learning. We developed and implemented a tablet-based visuo-spatial intervention in kindergarten classrooms aiming to foster the development of children's visuo-spatial and numerical abilities.

Findings suggest that social development interventions through elementary school can have positive long-term effects on school bonding and demonstrate the importance…
