It's easy to teach kids cuz I'm a kid myself...just make sure whatever you are teaching, make it simple but not all the time because keeping it simple all the time, they wouldn't be ble to understand, I also like pictures in whatever the person is teaching me so that I can have imagery cuz I'm more of a visual learner. You can teach as long as you want but you need to keep your audience active and alert so they could realize that whatever they are being thought is serious or important (or not) so that they could also remember what they were thought. Also add in a hands-on activity cuz some kids learn like that and also make sure to amplify your voice so they could hear you.
