I've tried to explain compound interest to my eight - year - old daughter. When I have finished it, she summarizes back to me, "So, you are saying if I put $ 100 in the bank, when I turn sixteen the bank will give me $ 200?" She has already grasped more of the concept than I understood at her age, but she couldn't clearly understand that until she sees them in action.
One day I gave her a Ziploc bag with a handful of pennies and told her over the course of a week I wanted her to give me a penny a day. I would deposit the penny in " The Bank of Dad" and compound interest would begin to accumulate the day she deposited the penny. At the end of the week we would check her bank balance.
Each day my daughter handed over one penny at the breakfast table and I deposited it in her bank. I gave her a "receipt" for her deposit and explained that she needed to keep up with the receipts to see how much money she had added to her account. In an effort to make this a little more realistic, I deposited a penny from my own piggy bank every other day to give her an additional four pennies at the end of the week.
On Sunday evening we gathered receipts and confirmed she had deposited seven pennies in "The Bank of Dad. " Then I opened the old film container and counted out its contents―all eleven pennies. "Hey, there are four extra pennies in there!" I explained that her original seven pennies had grown to eleven pennies because every couple days the bank paid her a penny for letting them use her money―that's interest. She paused and asked, "Dad, what would happen if you deposited like a hundred million pennies in the bank?

小学生10分钟应用题系列答案My teenage son Karl became withdraw after his father died. As a single parent, I tried to do my best to talk to him. But the more I tried, the more he pulled away. When his report card arrived during his junior year, it said that he had been absent 95 times from classes and had six falling grades for the year. At this rate he would never graduate. I sent him to the school adviser, and I even begged him. Nothing worked.
One night I felt so powerless that I got down on my knees and pleaded for help. “Please God, I can’t do anything more for my son. I’m at the end of my rope. I’m giving the whole thing up to you.”
I was at work when I got a phone call. A man introduced himself as the headmaster. “I want to talk to you about Karl’s absences.” Before he could say another word, I choked up and all my disappointment and sadness over Karl came pouring out into the ears of this stranger. “I love my son but I just don’t know what to do. I’ve tried everything to get Karl to go back to school and nothing has worked. It’s out of my hands.” For a moment there was silence on the other end of the line. The headmaster seriously said, “thank you for your time”, and hung up.
Karl’s next report card showed a marked improvement in his grades. Finally, he even made the honor roll. In his fourth year, I attended a parent-teacher meeting with Karl. I noticed that his teachers were astonished at the way he had turned himself around. On our way home, he said, “Mum, remember that call from the headmaster last year?” I nodded. “That was I. I thought I’d play a joke but when I heard what you said, it really hit me how much I was hurting you. That’s when I knew I had to make you proud.”

It’s you and I who are to blame for the state of the earth. No question about it. It’s our life-style that is threatening life on Earth, so we must make the changes. The good news is that many of those changes are really quite simple, even enjoyable, but for every careful step we take as individuals, we must press government and industry to take a big step on our benefit. And we must start now. Tomorrow’s too late.
My aim this year is to persuade as many of my friends and colleagues as possible to choose the train, and leave their cars behind too. My gardens have been pesticide(杀虫剂)–free zones for years and I enjoy seeing more wildlife on my doorstep as a result; I’ve tried to reduce my contribution to water pollution too, by using environment-friendly, phosphate(磷)–free washing powder , and by no longer thinking of the toilet as a suitable waste-disposal(处理) point .
I ran after a young lady through town recently to give her back the piece of paper she had carelessly thrown away. She disappeared into a shop, and when I followed her inside and made my presentation, she was doubly embarrassed--she worked there, and the boss gave her a ticking–off too. I’ve started asking fellow drivers at gas stations why they aren’t using unleaded (无铅的) petrol . These are small things, but we have to start somewhere, and every little does help.
