homophone |ˈhäməˌfōn; ˈhōmə-|
each of two or more words having the same pronunciation but different meanings, origins, or spelling, e.g., new and knew .
• each of a set of symbols denoting the same sound or group of sounds.
"there" denoting a place
"their" denoting belonging, possesion
"they're contraction of the two words they and are.
2 Don't confuse their, they're, and there. Their is a possessive pronoun:: I like their new car. They’re is a contraction of 'they are': | they’re parking the car. There is an adverb meaning 'at that place': | park the car over there.
I told mine to associate there with here since it's the same with a "h." They know that here is a place/location so there is a place/location too. For "their," I pointed out that there are two different vowels so the word belongs to more than one thing. For "they're," I tell them to always fill in "they are" anytime they use there, they're or their to see if it make sense. If it does, that's when to use it.
