Essentially, you put the bridle or halter on, whichever is safer in your situation, if you're daughter doesn't have soft hands and your horse responds well, use a halter, if the horse needs a bit, use a bridle.
Then run lines 2, 14 feet lunge lines from the bit/rings through the stirrups on your saddle. If you're English, I like to roll up the stirrups so the reins are held higher, if western just set them slightly higher. Then you stand well behind and slightly to one side (so you're no where near kicking zone) then you can either use a whip or I personally tap the reins on the horse's hind end and use the 'walk on' verbal command.
Use the reins like as if you were riding. Most well trained horses know this skill, most are taught before they are ridden, if your horse doesn't know it doesn't take long for them to figure it out if they understand reins and the 'walk on' command. Eventually you can do this at the trot too. But I like to do this through obstacles, over poles, tarps and all sorts of interesting things! Trying to weave cones while line-driving is interesting fun too!
Obviously you should try this yourself first to see how your horse does and work out all the bugs so you could teach your daughter. I do this out on trails too just for the fun of it!
