"The teacher walks to the beach."
Translation:O professor caminha para a praia.
Well this is my first time commenting in Duolingo, about time right? But I can tell you this, "para o" is the same as using "ao" which is the way you say going "to the" supermarket. "Para o" and "ao" is the masculine form. So coincidentally, the similar case occurs for feminine places when using verbs of motion, but notice, you would say, "para a" but if you try to say "a a" it looks silly right, so you know "à" would be like saying "a a". lol
to the para o = a para a = à
