's body is covered with thorns. This should be most people's first impression of the hedgehog . When talking about hedgehogs, the first image that comes to my mind is an apple stuck on the hedgehog's back.

Apart from this, I have never thought about whether hedgehogs are viviparous or can they lay eggs?

"The Egg of the Hedgehog" mainly depicts a hedgehog who, after seeing a duck mother hatching an egg, decides to find an egg to hatch on his own, thus starting the journey of hatching the egg. The hedgehog shows off everywhere with the caterpillar crawling out of the chestnut - it is the egg it hatched, which makes people laugh but also deeply touches them.

's simple story describes the typical characteristics of children's cognitive development rules and - relative concreteness. The educator Piaget divided human cognitive development into four stages: sensorimotor stage (0-2 years old), pre-operational stage (2-7 years old), concrete operational stage (7-11 years old) and formal stage. Operational stage (12-15 years old). In the preoperational stage, cognition is relatively concrete. Children's thinking at this time is focused on the intuitive state, relies on appearance, and appears rigid and lacks flexibility. In the

picture book, the little hedgehog saw an unpeeled chestnut with a round appearance covered with thorns, which was so similar to the hedgehog curled up while sleeping, so he thought it must be a hedgehog egg. This is a typical cognitive characteristic of children in the preoperational stage - only looking at superficial features of things.

In addition, children’s tendency to imitate is also vividly reflected in this picture book. After the little hedgehog saw the mother duck hatching eggs, he also wanted to hatch eggs. At the end, after the other five hedgehogs saw the "hatched eggs" of the little hedgehog, they also began to hatch the eggs. This is a characteristic that children like to imitate.

The entire picture book is painted with rich and thick oil paintings, but it gives people a refreshing feeling. Large expanses of green, layered and intertwined, create a sense of dense forest, yet still retaining vitality.

Main content:

The little hedgehog saw the mother duck lying next to the two eggs and asked the mother duck what she was doing. The mother duck said that she was incubating eggs, and when the eggs broke, ducklings would come out of them. The little hedgehog also wanted to hatch an egg. When it found a round chestnut wrapped in short green thorns under a tree, it thought it was a hedgehog egg. So, it started hatching eggs like a mother duck. After the five hedgehogs saw it, they curiously asked the little hedgehog what the little hedgehog was doing. The little hedgehog said that it was incubating eggs to protect it from the wind, rain, and the scorching sun. The next day, a strong wind suddenly blew and it rained heavily. The little hedgehog hurriedly looked at the eggs on the nest and found that they were missing, so he searched everywhere. Finally, the egg was found under a branch that had been blown down by the wind, but the egg had been broken. The little hedgehog cried sadly, but he still took a closer look and found a chestnut crawling inside. A caterpillar emerged. The little hedgehog thought it was the egg he had hatched. After showing it off to his companions, the other five hedgehogs also thought it was the egg hatched by the little hedgehog, and they each found five green chestnuts to hatch the eggs.

picture book expansion:

1. Take a popular science trip about hedgehogs to learn about their characteristics and living habits.

When a hedgehog sleeps, it curls up into a ball, like a small ball with spines.

2. Observe the chestnut hanging on the tree and discuss why the hedgehog thinks it is its egg.

The outermost layer of the unpeeled chestnut is wrapped with a layer of hard thorns, like a hedgehog curling up into a ball when sleeping.
