What are some games for horse riding lessons?

I teach horse riding lessons for riders as young as 8 up to adults. They are all abilities from those who have never ridden before to very experienced riders. I want to make my lessons more fun by doing games and fun exercises (like around the world) for all abilities, any ideas?What are some games for horse riding lessons?
around the world (like you suggested)

simon says proberbly for the younger members)



We do toilet paper races (for more advanced riders there's an obstacle course to navigate) toilet paper on the saddle and who can keep it there the longest.



Egg and spoon races



Water races (rider loads up a leaky container with water, and rides to another bucket dumps it in... We either do the first to transfer all the water with the most in the bucket wins... Or we time it for lots of people so that it's the most water in the bucket within the time allowed)



Soccer ... Get the horses to push a large pilattes ball ($10-$20 at Walmart or similar department store ) this can either be set up as a soccer match with opposite teams attempting goals... Or for more challenge set up a course of obstacles to push the ball through or around and set a time limit)



Flag races are pretty standard



Costume races are oodles of fun... Dress you or you and the horse up with items from a sack... Person to get the most items in the least time wins. Add challenge by having rider remount and ride through poles, obstacles or even race to the finish.



Beach ball polo... Grab a floor hockey set from a place like dollar store (I go with cheap because they do as well as anything else) and an inflatable beach ball... Push the ball with the stick... Attempt to keep the ball away from opposite team, and score a goal marked by trot pole. or cushion polo



tie a helium balloon to your waist and try to pop your opponents and the last one with the balloon wins.
