Preschoolers typically interact with same gender peers 3 times more than with opposite gender peers. Gender segregation begins around age 3 and increases dramatically during preschool. By the time children reach age 6 ½, they are interacting with their same gender peers 11 times more than with opposite gender peers.
Same gender play and friendships continue to increase and peak during elementary school.
So, when children spend significantly disproportionate amounts of time with their same gender peers, how can we get boys and girls to learn successful strategies from each other?
