Close out the practice and allow the players to show you what they learned.
Limit the number of times that you pause the game.
Be Positive- Catch them doing what you worked on and offer praise. (i.e.) Tommy- great work moving into the space between the defenders. or Sally, great job keeping your eyes up and finding the open player.
Close out the session with loads of encouragement and allow the players to tell you what they learned about solving the problem or question of the day.
