(((((((Lupita)))))))
You read like a confident teacher in control of the situation.
Separating them is always productive ..... they don't like it .... but tough it's your class and your call.
And sending disruptive students to the principal is the norm, enables him to deal with the student accordingly, contacting the parent etc.
Your job is to teach them - he is paid to manage.
Cannot comment on how you decide to grade them - you're the teacher and you have their coursework etc.
Do you have a moderator system to audit the final grades?
So glad to read that your day has gone so well and also it's wonderful to read your plans for the rest of the week.
As you say, you're trust is in G-d, so you're in good hands Lupita.
God Bless you.
Take care.
