  1. Story introduction

Hello, dear children! It’s great to see everyone again. The teacher brought my friend, guess where it will appear from? Dong Dong Dong… (Shows hand puppet) Who is it? Does anyone know it? It is a brown bear that likes to hibernate.

The teacher secretly tells you that today is the birthday of the brown bear. It has invited many good friends to its home, and also invited all the children in our class. Would you like to attend the brown bear’s birthday party? I heard everyone said yes.

However, the little brown bear is not happy at the moment because it wants to invite guests to dine at home, but it has not prepared so many dishes and needs someone to help buy the food. Children, would you like to help buy groceries? (Willing) You are really helpful children. The teacher can’t help but give you a good one. (encourage rhythm)

  1. Rules explanation, guide to observe the picture and think. (Open course app)

① Okay, we have arrived at the vegetable section of the supermarket. The salesperson is busy with other tasks. We need to help sell vegetables.

Ask the two people sitting in the salesperson’s seat to be the salesperson. The 4 people sitting in the customer seats act as customers. Our activity will be held several times, and everyone will take turns being a salesperson.

② Let’s take a look, what kind of dishes are there in the supermarket? (You can learn the names of vegetables from left to right first) There are eggplant, bitter melon, potato, purple cabbage, small pumpkin, spinach, carrot, and cucumber.

So what are the dishes that cost 1 yuan? (potatoes, carrots)

What are the dishes that cost 2 yuan? (eggplant, bitter melon, cucumber)

What are the dishes that cost 5 yuan? (spinach)

★We observed that we only saw one or a bundle of each of these vegetables, right? The teacher will tell you a little secret. When we take away the dishes, there will still be some dishes in front of the salesperson.

★What else did the children see?

Rich, right?

Then there is a stack of money in front of each customer. How much is the total? The child who is the customer quickly counts, how many are there?

(5 pieces worth 1 yuan and 1 piece worth 5 yuan, how much does it add up to? 10 yuan)

③ Through observation, we have learned about the variety and quantity of vegetables, as well as the selling price of vegetables. We have also counted the money that can be used to buy vegetables. Each customer has 10 yuan. Before starting the vegetable selling activity, we have an agreement. , that is, to buy and sell according to the teacher’s instructions.

Each table is a group, and the child near the podium is the group leader of this activity and is responsible for group discipline. Customers need to queue up to purchase in order and are not allowed to jump in line.

During the process of buying groceries, we must live in harmony with our friends, help each other, and not argue. The teacher wants to see which group has the happiest cooperation.

Activity summary

Little Brown Bear is very grateful to the children for their help so that the birthday party can be held smoothly. That concludes our activities.

Overall, you are all great.

But while a child was helping the brown bear buy groceries, he ran to the side to play. Is this right? If every child was like this, our class would not be able to complete the common task today. So you must observe discipline in class and listen attentively.

During the game just now, the teacher also saw that the XX group was very united, very orderly, and cooperated happily. Teacher gives you thumbs up…

And XX child, as the team leader, helped other customers buy groceries…

Children, have you learned how to buy groceries? When you get home, are you willing to help your parents buy groceries?
