Question: Can someone check my translations?

pwede rin,Magbihis ka na(Gumayak ka na.. lol this is considered deep but i couldnt help myself because this is what the dads say in Tagalog stories haha).Oras na para pumasok (sa paaralan/eskuwelahan)

I commend you for homeschooling your kids and trying to incorporate Filipino into your daily lessons.
Ito ang ilan sa mga iminumungkahi/suhestiyon ko na maaaring gamitin mo din.Get dressed = " Magbihis ka na" as @PinoyTaj suggested is more the literal and appropriate to use. I also use/say "Maghanda ka na" (to get ready) to my kids and when I say this, I expect them to not just be dressed but they should have brushed their teeth, combed their hair, packed their bags/lunches etc.
Expected replies to this can be : " Bihis na (po) ako."
" Magbibihis na (po) ako."
" Handa na (po) ako." Time to start school = "Simula na ng klase." or "Oras na para magsimula ng klase."
Since you are homeschooling, when you say this, you are taking the position of the teacher ( my teachers in grade school used to say this to signal the formal start of our lessons/ classes)
'Paaralan' refers to the school building or school system.I am coming= Parating na ako or as we would answer our mom " Nandiyan na (po) ako." I may not explain it very well in English but the language (Tagalog) has this context where to express a higher degree of commitment to an action we would reply as if we have done the expected action already.Hope this helps.

@PinoyTaj you made me remember my grandpa.
"Gagayak na ako."- He would say this to us when he is about to leave to go back to the province. I have not heard it being said/used for such a long time now.

Thank you all for your help! Salamat!
