Throw in violation?
 

After a made basket, player grabs ball, turns around without going out of bouds throws in to a teammate.

Is this a violation, or do you stop play and tell them to take the ball out?

I would assume that level of play matters?

Throw In Violation ...
 

9.2.2 SITUATION C: A1 scores a basket. After the ball goes through the net, B1
grabs it and makes a move toward the end line as though preparing to make a
throw-in. However, B1 never legally steps out of bounds, both feet remain
inbounds. B1 immediately passes the ball up the court to a fast-breaking teammate,
who scores a basket. RULING: Cancel Team B's goal, throw-in violation on
B1. The ball was at B1's disposal after the made basket to make a throw-in. B1
must be out of bounds to make a legal throw-in. (7-4-3; 7-5-7)

Your welcome, but I didn't give you a complete answer. If your working games with second, and third, graders, my advice, again, is to "check your local listings".
