I read your other thread and this one but have not yet read the responses. So this will be long lol
I will make a short list that helps me teach my cousins who are from 3-15 yo
Its purely games and rewards in a fun environment
Rewards - being lead on trail ride, walking on loose lead/lunge line around cones/barrels, stars and a chart- whoever has the most stars at the end of the month can do something special with the pony... usually gets to put dye on the horse or I buy them a small gift like there own halter or something...
First lesson is always. Grooming, leading, and having the child move the horse in all directions. That way they feel they are in control. (i am almost positive I read you did this in your previous thread)
Second lesson involves them helping me tack up the pony - they must pick up and touch every piece of tack. While I ask questions like where does this go before I put it on, what is this called blah blah blah and then I put them on. I spend about 5 minutes leading them 2 steps and practicing stopping and releasing then continue until they get the hold of light hands... the first few times are a little a rough to watch :p
Then we practice turns around barrels or cones (it gives them an object to focus on plus you can relate it to barrel racing.. :) any mention of racing usually gets a kid excited.
Third lesson refresh stops and turns and work on lunge line. Practice hands up for balance, touch the tail, touch the head touch...etc that way they have to focus on how they are sitting... I know this will probably get me negative points but when I notice them not paying attention I put the pony into a trot when there hands are up.. and when they get caught off guard and start to slide they grab the horn... that's when I tell them why they need to focus... its very easy to fall and get hurt.. usually once they realize that chance the hardway like that they stop...
Eventually when they are comfortable by themself I have beanie bags on the barrels and make them walk the pony to barrel get beanie and bring it to another barrel or drop it in a bucket...etc.. and slowly work up from there...
Hope it helps. What helps me even more is trying to act like a kid... it helps relate to them :) goodluck
