I am working with children right now, and I want to give them the right instructions ;)
So, here are my sentences:
Put the puzzle back inside its box, please. Use "in" here.
Put the books ?in? the bookshelf, please. We put books on a shelf.
Get ?in? the car, please. This is OK, you could also use "into".
Go ?into? the house, please. Correct.
Go ?into? the bathroom. Correct.
Can you give me a short explanation, when I use in / inside or into, please?
