Score lots of goals. Dribble toward the goal, look up, and shoot when you can see it. There is no keeper, so just have a go, and go again straight away with another ball.
Set a small goal with no keeper and a start cone a short dribble away. Every child has their own ball. On the go, each dribbles in and shoots at the goal, then jogs to fetch another ball and repeats. Run several goals at once so nobody waits and the whole group is scoring continuously. Encourage shooting with the laces or the inside of the foot, and both feet, but do not overload them with technique, the volume of happy repetitions is the point. Move the start cone closer if they are not reaching the goal.
A five year old learns to shoot the same way they learn anything else, by doing it a great many times and enjoying it, not by being taught technique. So the single most important number in a shooting session for this age is how many shots each child actually takes, and everything else serves that.
That is why this practice is solo and continuous. Every child has their own ball, dribbles in, shoots, and goes to get another, which means there is no queue and no defender in the way and no goalkeeper saving everything, just a constant stream of strikes at the goal. A child who takes forty shots in ten minutes learns more than one who takes four and listens to eight minutes of coaching.
Removing the keeper is deliberate. At this age a goalkeeper turns a joyful scoring drill into a frustrating one, since most shots would be saved and the reward that makes a child want to shoot again disappears. Empty goals mean goals, and goals mean they keep having a go.
The coaching is light on purpose. Look up before you shoot and use both feet across the session is about as much as a young child can hold while doing, and technique is caught over time from the repetition rather than taught from the touchline. The advice that overwhelms a young player is worse than no advice at all.
The one dial to adjust is distance. If shots are not reaching the goal the run is too long, so move the start closer until every child is scoring, because a shot that falls short teaches nothing and a goal teaches them to do it again.
And celebrate loudly. There is no shooting too early and no shot too ambitious at this age, and the happy noise around a goal is the thing that turns a child into someone who wants the ball and wants to score, which is the entire point.
Save it to your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block. Or start from a blank pitch and build your own.
