It's time to pack your school bags?

[Kwfine]

It was around 2:00 PM when I heard a teacher asking her class:
"Hey kids, please pack your school bags and prepare to leave!"

Would it be better to change the statement this way:
"Hey kids, please pack up your belongings and prepare to leave!"

Any idea?

Hi,

It very much depends on what the teacher wanted the children to do and where they were going. Were they going home or were they going on an outing in the school bus?

Hi Alan,

actually I would like to ask why it is not
"Hey kids, please pack up your school bags and prepare to leave!"
but
"Hey kids, please pack your school bags and prepare to leave!"

"They pack up something" and "They pack something",
are they different in meaning?

Both mean the same. You can say 'pack up' when you want the other person to speed up a bit.

Hi,

Yes, there is a little more urgency in 'pack up'.
