Some of the major male/female brain differences that are helpful for parents to understand is that there's a different layout in the brain in terms of the amount of the brain that's dedicated to visual-spatial functioning and verbal functioning. Girls more often have more of the brain dedicated to verbal functioning, which means that their receptive and expressive language tends to develop earlier. Entering kindergarten, girls are usually a year and a half ahead of boys in receptive and expressive language skills and in vocabulary. Boys on the other hand have more of their brain dedicated to visual, spatial and motoric kinds of function, and so boys are typically better able at gross motor functions, large body movements, throwing a ball and say hitting a target, visual-spatial kinds of puzzles. Now it doesn't mean that boys and girls can't learn equally well to do those things, it just means that more boys than girls are good at some things and more girls than boys are better at other things. The implications for parents are really, really important in terms of supporting their kids in learning to read and to write and being ready for school.
