TWEENS

Think of the age group just before teenagers, often around 10 to 12 years old, who aren’t quite kids but not full teens yet.

"Most middle schoolers" refers to kids typically aged 9 to 12, the transitional stage between childhood and adolescence. The term tweens—a blend of "between"—captures this in-between phase perfectly. It’s a common label for this age group, making it a straightforward answer once you recognize the everyday word for preteens.
