In my experience with elementary level students, I am constantly amazed by these kids imagination. However when it comes to math i find myself frustrated that their minds wander so much. Sometimes i want to just be like, "Super man and unicorns are not a part of math! pay attention!!!!" Reality is, that just doesn't help. I began trying to revamp my ways of teaching so that super man could join us in our lessons. I found that using examples that incorporate the child's imagination works wonders. They being to laugh and enjoy themselves when I am tutoring them and the best part is....THEY PAY ATTENTION! The fun examples also help them to remember math concepts when they go to take their tests. It is a win win for everyone. A basic example could be "superman already saved 4 people last week but this week he saved 5 more people from a burning building! So how many people has he saved?" We have taken a basic 4+5=9 math problem and made it fun for them. Sometimes they'll say things like "how about he saved them from a giant dinosaur!?!" and that's when you know that they are engaged.
Kids aren't interested in the methodology behind math and they need entertainment and examples that they can connect with. I would encourage every tutor to try this technique.
