This drill is fun and great for children and adults alike.
We take a rope long enough to hold in both hands as the middle is on the ground.
Pass through forward and back. make the rope between your hands shorter by two fingers widths. Repeat.
As you progress, you will find it harder and harder to pass through. Use the angles of the body to pass and moving your legs and hips beyond the linear path.
You can see a chain version of this drill in this video:
and there is a second part with much more work:
Take a rope or a belt and hold it under your armpits. use your body movement and transfer it from side to side and front to back using just your body and arms till your elbows. Next take the belt and hold it in your elbows and move it around. now hold it at a comfortable distance in your fists and see where you can go with it and with a partner defend yourself by moving with the belt. From time to time shorten the distance between fists and see how you learn from this.
It is also good to check how you work in tight places like under a door or sitting next to a table. Giving yourself limitations lets you find new ways to move and solve problems. This way you have a better sense of movement and intuition when a problem arises.
This is a great way to teach children to move and defend themselves in a game way. Give two kids a jump rope or a long belt and each one holds one end. Now they try to loop it around the others neck (without giving it too much pull) as the other moves first with just the body and neck and than with the hand that is free and than with everything. you can also have a two on one where one kid holds two rope ends and two other kids work with him and so on. Adults can do this too with the same effect and move later on to the chain which is less kid friendly.
