<p>My children are three years apart and they love to study together. My son in particular is a fantastic tutor to his younger sister. He makes everything fun and silly, so, for example, she'll say that Rome was founded in 753 BCE and she remembers this because it's a palindrome (obviously, it isn't -- it's just something funny they made up). Studying Latin vocab is always a riot because they come up with ridiculous stories for every word she doesn't know. He makes her learn History as a story, not just dry facts. Why, what came of that, what parallels are there between that and this? He really gets her thinking! Though they laugh constantly, he takes teaching her very seriously and is quite the task master. But she can also help him when he's doing Latin translations because she knows a lot more Latin than I do, and her Grammar knowledge is better than his was at that age.</p>
