I teach "be used to" and "get used to" together, because "get used to" is much easier to explain straight after setting a context for "be used to".
I use the context of being used to driving on a different side of the road. So if you're British and are teaching in a country where they drive on the right, then you're in luck. Likewise, if you're American and are teaching where they drive on the left - you get the idea. (If not, just use "Tim" as your example, rather than yourself).
First, ask your students which side of the road they drive on in their country, and in the UK. Then ask them what it was like for you (or Tim) when you first arrived in (let's say) Spain. You want to elicit "strange" or "not normal".
Now tell them that you've been living in Spain for a year, and ask them if it is still strange.
