I have a little introductory exercise to do as homework, I have to do a little script which takes 2 arguments, first argument a directory the second argument a number.
The functionality is to classify the files from the directory into 2 subdirectories. First subdirectory for files larger than the second argument and the second subdirectory for smaller files.
My thought were to take $5 from ls -l but i think its not a good idea, can someone give me any recommendation? Thank you.

I suggest starting with the Find man page. Then possibly taking a look at How to run find -exec?. Of course it's probably also a good idea if you make a stop Here before writing any shell scripts.

How about use find with 'size' parameter? It's very simple: find . -size [+-] <size>.

No need recursion AFAIK, if OP is a beginner, I think he should use basic conditions/algorithm, not advanced tools

As you stated, don't parse ls output.
You can check file size with stat -c '%s' file (bytes) in a for loop. As a starter :
#!/bin/bash
cd "$1"
for file in *; do
# code/tests here on each "$file"
done
Then you can use bash arithmetic to do some conditions on file size.
Test by yourself to implement this, and feel free to edit (and/or comment) your post if you have some problems with code
Another solution (from comments), use find with the -size switch if you remember your teacher had talked of this tool, ex :
find "$1" -size +100
Check
man find | less +/-size
