How did Katniss and Gale become a team?

Answer 1

Katniss was in the woods, at around 12 years old, and she saw a snare which successfully managed to catch a rabbit (I think there was more than one but that doesn't matter). When she goes out to touch and observe the snare, Gale tells her that "Stealing is punishable by death" and that's how she first meets him. They don't get along well at the start because Katniss said how they haggled over things, but they became a team a few months after I suppose.

Answer 2

Katniss and Gale became a team by helping each other provide for their families. They shared hunting techniques, and other ways for survival. Katniss showed Gale how to collect edible plants, and he showed her how to set traps.

Answer 3

They're fathers both die in a mine explosion. Gale traps and Katniss shoots. They are perfect for each other.
