I have a textbook and shows a few example sentences with "I think" all of them use the conjunction "that":
1. I think that her boyfriend cooks well. 2. He thinks that no one is home. 3. They don't think that she plays the guitar well.
Then after several pages, I see a new example, but this time without "that":
4. I think math is interesting and important.
But no mention why "that" was dropped in the fourth sentence. Does the textbook want to show me that it is not important to use "that"? So, I can make the first, second, and third sentence without "that"?

As a conjunction, that is usually optional, especially when it begins a clause which is the object of the verb preceding that. All your examples are correct with and without that. CB
