Try pass the buck .split group in two on a small sided pitch ,one group starts with all the balls,play the balls into other half for 2 minutes or until all the balls are played. rule ball must stay on pitch .As a progression let the other team return them for last 20 seconds or so In level 1 book
or even more fun a rounders type of game 15x 15 area 2 teams players on outside have to run around ,or pass or dribble or running relay around pitch. before the team in the middle.in a diamond shape completes set amount of passes and /or scores.
Have fun with them make it competitive use their natural energy
Good luck in the future Assistant bossman
Gradually cut down the numer of balls, at first its mayhem but over 3 weeks - 15 minutes each week we have seen a vast improvement. The majority now pass AND move - still waiting for the name calling !
Even the parents have remarked how a simple exercise has worked.
best of luck bladesman
