The grade that is usually the last year of elementary. The 5th graders love being the oldest in the school and the 1st graders think they are soo tall and scary. Once you see the middle and high schoolers you’ll realize how small you are.
Those 5th graders are in their last grade of elementary school!

Is when the time when you start to become a little bit mature. And you start to realize that your a tween (10-11 year olds). They are going through puberty. You are probably interested in your friends more than your parents. You probably will start to argue more with them. Hormones are going crazy! *it might hit you hard*

Tween: ugh

Mom: why are you always so moody?
Tween: mom you don’t understand!
Mom: go to your room young lady!
Tween: ugh! *slams door*
5th grade changes.

10-11 year olds who are so desperate and impatient with love. 5th grade dating is when two children think it is a necessity to be in a relationship. This relationship consists in saying "I love you" over text and waving to each other in the hallway. That's it.
5th grader: OMG I love my boyfriend so much he is my everything!
Logical teen: kid you're 5th grade dating...calm down
