In the hall / gym, split the children into two groups and then number them. For example, if there are 20 students in the class, split them into groups of ten, then number each student from 1-10.
Have them sit on opposites sides of the hall / gym, then call out a number, i.e. 3
Both number threes will get up and run to the middle of the hall where a duster (preferably a soft one, not one with a hard back) and two newspapers rolled up (the hockey sticks) are waiting. Each child takes a newspaper stick and tries to hit the duster into their goal.
If someone scores, another number is called out, and the next two will have a go. If no one scores after a few minutes to make sure everyone has a go, call out another number, and the ones playing must drop their “sticks” where they are and the next students have a go.
This can also be played in pairs when the teacher calls out two numbers etc.
