Set and use a simple on-ball screen.
The two halves of basketball's most-run play: a screener who arrives, stops and stays legal, and a ball-handler who waits and drives shoulder-to-shoulder off the screen. The chair keeps it simple enough to groove the timing.
In games: Teams meet ball screens constantly from about U12 up — players who can set and use one create open shots all game instead of dribbling into a set defence.
U12: walk the timing on the chair — early drives and drifting screens are normal. U14–U16: expect it live against defenders, with the screener choosing roll or pop.
1 ball, 1 hoop, chair/cone
A ball-handler up top, a screener beside them, and a chair or cone standing in as the defender being screened.
The pick and roll is basketball's most common play — a great intro for older teams.
Add live defenders on both players.
Use a chair or a coach standing still as the defender and just walk the timing through.
Let the screener choose roll or pop, and the ball-handler has to read it.
