'Tween' years represent critical time in literacy development
How many 10- to 12-year-olds do you know? They are quite delightful and highly skilled individuals. They are often very agile and nimble at this age, as more than two-thirds of accidents occur before age 10. By age 4, 50 percent of our brain is developed, and 80 percent by age 8. By age 12 to 13, brains are 100-percent developed. So, it is a little scary, but these 10- to 12-year-olds have nearly developed brains. The people around them have done much imputing; now, they are using the information.
