The best way to revise the paragraph to connect ideas is by combining sentences 2 and 3 with the transition word therefore. This creates a clearer connection between the idea of children exploring activities they are interested in and the positive outcomes of self-directed play and learning, such as increased confidence and independence.
Revised sentence could read: "This layout allows children to move freely throughout the room, delving into activities that interest them, and therefore promotes confidence and independence in kids."
