First of all, the insect party

Teacher: There are many small insects living in the forest. Look who they are.

Teacher: Here comes another (little ant). Where have you seen ants? Ant's home is everywhere, everywhere.

Teacher: Here comes another (ladybug). Do you know what kind of ladybug it is? (Ladybug septempunctata) Is Ladybug septempunctata beneficial or harmful? Why? (Because it eats worms), but not every kind of ladybug is beneficial. There are twelve ladybugs and twenty-eight ladybugs here. What are they eating? (Leaves) Yes, it destroys plants, so they are pests.

Teacher: Who is the other little insect? (Grasshopper) What can it do? It can jump around on the grass.

Second, insects line up.

Teacher: The little insects should go out to play in neat rows. Who can help them line up along this road?

Teacher: Who do you think ranks first? Who came last? Do you think so? The teacher will give you a hint.

(Show the arrow opposite to what the child said) What does this arrow mean? It turns out that the direction of this arrow is to let us count from here to there. Now who can tell me who is the first? Can you say it completely? What about the second one? Where are the grasshoppers? Who was the last one?

Teacher: Which child can look at the arrows and tell their arrangement completely?

Teacher: Would you like to talk together?

Teacher: We must look at the direction of the arrows clearly before we can judge their positions.

Teacher: Little Arrow is going to play hide-and-seek with us! (The teacher changes the position of the arrow)

Teacher: According to the direction of this arrow, who can describe their arrangement completely? You also said ...

Teacher: Let's look at the direction of the arrow and say it completely.

Summary: It turns out that the direction of this arrow is to let us count from here to there.

Third, the insect found a home.

Teacher: The bug is a little tired from playing. They want to go home and have a rest.

Teacher: Look, what floor is the home of the little insect on? (4th floor) What floor is the first floor? Why? (Introduction: Think about whether the house you live in is the upper floor or the lower floor. ) So, the ground floor is the first floor. Let's give it an arrow, right?

Teacher: What floor is this? (Second floor) What about this floor? What floor is the other floor? (third floor)

Teacher: Then let's look at the direction of the arrow and count it together. (First floor, second floor ...)

Teacher: After determining the floor, bugs can live in it. Who will help them live there?

Teacher: Please tell us how they live. (What you said is really complete)

Teacher: Can you speak as completely as he does? Do you remember where they live?

Teacher: Little insects want to be guests on other floors. They are naughty, let's close our eyes!

Teacher: Open your eyes and see where they have been. What floor is the little ant on now? What floor does it live on? See if it is right! ……

Teacher: You have a good memory! It seems that this little game can't beat our children.

Fourth, play games with insects.

Teacher: Look, there are all kinds of small insects here. They still want to play games with us! Do you know them?

(Pointing to the arrow on the right) Teacher: What does this arrow mean? (Counting from here to there) Yes, count how many rooms there are on each floor. Later, we will be divided into red team and green team to answer first. Whoever can find the home of the little insect according to my requirements will get the small sticker, and whoever gets the most small sticker will win! Do you have confidence?

Teacher: At the beginning of the game, Little Mantis lives in the first room on the first floor. Who found out? Is he looking for the right one? How did you find out?

Teacher: We can count which floor the little mantis lives on first, and then which room it lives in.

Teacher: Little Bee lives in the third room on the second floor. Who found it? (If the children can't find it, guide them to count together)

Teacher: Which team won today's game? (Red Team) Let's applaud them, and the children of the Green Team should not be discouraged and try to win the next game.
