Fun invasion game that encourages team work and tactics. Suggested by Physedgames
Equipment:
The suggested version uses a couple of gym mats at either end of a court, but if you have a court with large enough boxes or semicircles already marked out you could just use these*.
A court sized area indoors or outside. The game rules only need a centre line and a home base for each team at the far ends of the court/playing area.
Play
Place the home bases at either end of the playing areas. Divide into two equal teams. Each team goes into the half of the playing area opposite to their home base as in the diagram below (different coloured mats are purely to demonstrate their placement in the opposing team’s area).

The objective is for all team members to get to their mat/home base.
Players can be stopped by members of the other team by tagging. Once tagged a player has to sit down where they are.
Players that reach the home base are safe and cannot be tagged.
Tagged players can be released by being touched by a teammate who has not been tagged while in the opposition area. Once released, both members of the team have to walk back to their own side, but are safe from being tagged until they reach their side and once more are in active play again.
Players who have reached the home mat can also release team members who have been tagged, but both also must walk back to their teams side, before attempting to reach the mat/home again.
Whenever the teacher/leader feels like it, they can call “Yoshi”. All players, including those who were tagged and sitting down, must get to their mat/home.
First to have everybody on the mat wins.
* – The size of the home bases could become part of the strategy. You need bases large enough to hold everybody on that team, but the smaller they are the more the team has to think about how to get everybody on at speed.
