rambam says that you should give to family first.
my question is what if the family does not know how to manage money? what if i know that if i give my family money, they will waste it and suddenly not have enough for food/education for children?

Practically speaking, in many cases you can give it to them in a way where there's (more-or-less) a guarantee that it won't be wasted. For example, give them actual food, or a check towards their children's tuition (made out to the school).
See Prisha, Tur Even HaEzer 71:1.
In theory, family has priority with regards to charity. However, the standard obligation of child support is only until age 13 (note: twentieth century rabbinic authorities have raised it to 15 or 16, see Yechaveh Daat 3:76 and similarly this). It was assumed that the average "grown-up" child, in most cases, could fend for themselves (including begging, if needed), thus there is no blanket obligation to support one's adult family. In the unfortunate case that they would not be able to do so, then their charitable cause would have priority over a random stranger's. All else being equal, is how I read it.
There are cases where people will use their received charity simply unwisely; sadly there are cases where it would actually be self-detrimental. It should be remembered that the goal here is to help people, and sometimes the best way to do so is to say "no." The Talmud says the reward for truly helping someone sick (which may involve changing their bandages and hearing them scream, or being called all sorts of names because you won't give in to their pleas for a cigarette) is friends like Na'aman's, who got him cured [by telling him no], and not friends like Rehoboam's yes-men who caused him to lose half his kingdom.
I think each case may have to be decided on its own merits; a rabbi who understands the particulars of the situation may be helpful, and lastly, it's possible that certain questions of tzedaka prioritization are actually up to the giver's sense.
The Gemara says that when you give a person charity, if he is used to eating expensive meat then you should give him according to what he is accustomed to. This would imply that it is still considered charity even if to me and you it seems wastefull.
