Can you make a loud bang（响声） with just a piece of paper（about 30cm×40cm）? The banger produces a quick and large movement of air, forming a sudden and powerful sound wave. This rushes through the air toward you and you hear it as a bang. Now let's make a banger together.
1. Fold（折叠） the longer sides of the paper together. Then open it out.
2. Fold the corners into the first fold.
3. Fold the paper in half along the first fold.
4. Then fold it in half again lengthways（纵向地）. Then open out the second fold.
5. Fold down the two sharp corners.
6. Fold the paper back along the second fold to make a triangle（三角形） shape.
7. Hold the banger by the two sharp corners. Flick（甩动） it down quickly and it makes a loud bang!

Money is something we use every day to buy things. But do you know what money’s real value is? It’s not just about how much you have. For example, if you save a little money each week from your pocket money, you can buy something special later. Saving teaches us to be patient and plan for the future.
Money can also help others. When you donate money to a charity, you’re using money to make the world better. That is a wonderful way to show money’s value—it’s not just for yourself, but for sharing with others.
However, money isn’t everything. Some of the most important things in life, like family and friends, can’t be bought with money. When you’re sad, your friend can give you a hug—that’s more valuable than any toy. So we should remember: Money helps us live, but love and kindness are more important.
Learning about money early is useful. You can start by making a list of things you want to buy and seeing if you can afford them. For example, if a video game costs 20, you can calculate (计算) how many weeks of saving 5 you need. This helps you understand the value of work and patience.

A. Money should be spent on toys.
B. Saving helps us plan for the future.
