Normally, kids have curiosity(好奇) about everything around them including animals. As a parent you are willing to teach everything to our children because you want to develop their EQ and IQ. But a few people have some troubles in how to introduce animals to their kids. Here I have some advice on how to do that.

1. Visiting a zoo.

This way must be the best choice to choose. If you have free time or maybe on holiday you can take your children to the zoo. Kids usually are excited to see live animals and feed them if possible. It can be an unforgettable moment for your children when they visit so many animals in a place. Parents can describe an animal to their children so they can learn something about that animal.

2. Doing a coloring activity.

If you have not free time or just have a short time, you can choose this. Actually doing animal coloring activity is mostly used by parents and teachers to tell children about an animal. You can download free animal coloring pages through the internet or you can buy your children an animal coloring book.

3. Doing a paper craft.

If it sounds difficult you can skip this method. Just forget it. Generally, the difficulty level depends on your paper craft models. You can find free animal paper crafts on the internet but make sure of the difficulty level. Remember your purpose is not about how beautiful your paper crafts are but to describe an animal to your children.

4. Story telling.

Have you heard about an animal story when you were a child? You still remember it? How about the character of those animals? Yeah! It is still in your mind. You can buy a story book of animals and read it for your children.
