Translation of それを持って来させる


I have the following translation for class.

[code]

    勉強しなかった悪い学生に、
    家で漢字を三百回書かせて、
    それを持って来させて、
    それから、教室の前に一時間立たせた。
    
[/code]

So far I have the following.

[code]

    Bad students who didn't study
    I made them write kanji 300 times at home and
    .... and
    after that, I made them stand at the front of the classroom for an hour. 
    
[/code]

That 3rd line I am really having problems with. I see the "to make someone"
structure with the 来させて. And then the て form of "to have" with the 持って. So "I
made them to have this and come"? Or I think て and 来る can mean to come to a
point. So maybe "so as to make them get to have this" like in an "understand
this" sort of way? I just don't know...




持ってくる means to bring something with you (hold/carry than come) so the 3rd line
is something like "...and had them bring it back (to class)"
