I am not certain for sure let me direct you to this site en.wikipedia.org However when I think of a preteen I think of 12 years old, maybe 11 in your case. Hope this helps you.
They are about 11,or 12 years old.
You have to be 12 t be a pre teen
I think of 11 and 12 year olds as being preteens. Depending on the maturity level of the child. I did not think it was like an official thing, just the ages they are as they approach the 'teen' named years.
A preteen is a child who is either 10, 11 or 12. As soon as they turn 13, they are a teenager.
About 10 or 11 before they become a teenager. The could also be called tweeners
I think somewhere around from 10 - 12
I think it's 12...Because at 13 you're a teen. And "pre" means before.
You have to be twelve because its the closest age under 13 and 10 and 11 are tweens
