Suppose you've been working on an equation. You can't find a solution to it. So wou want to ask your classmates or friends for help. Would the use of "kick in" fit in this context?
"I can't do it. You guys want to kick in?"
----- Not an ESL teacher -----
I can't do it. You guys want to help me?
I can't solve this one. Hey guys, wanna try it?
I can't solve it. Could you help me?
I can't solve this one. Can you?
I can't find a solution. You guys, wanna work it out?
I can't solve it. You guys, wanna pick this one?
I've found kick in with a "contribute" meaning here: kick in - Idioms - by the Free Dictionary, Thesaurus and Encyclopedia.
But I don't think it fits this context.
