Scenario introduction – vegetable supermarket

discuss:

Have your children ever bought anything by themselves?

What have you bought?

Getting in:

The teacher wants to invite friends to have dinner at home in the evening.

Now I need to go to the supermarket to buy fresh vegetables.

Because I have a lot of friends, I have to buy a lot of groceries. I can’t handle it all by myself. Are you willing to help me buy groceries? You are such good, helpful children. Let’s go to the vegetable supermarket together!

Understand the RMB

★(The courseware screen is displayed on a large screen to guide children to understand the RMB) We came to the vegetable supermarket together. Do you know what this is? What’s its name?

★Some children say it is money. By the way, it is called RMB. Guess how many yuan this is? (Display 1 yuan, 5 yuan, and 10 yuan, and games can be used to increase children’s impression of RMB.)

★(Use questions and guesses to guide children to think about the relationship between the three coins.)

Does any child know how many 1-yuan bills equal to 1 5-yuan RMB bill?

How many 1 yuan bills are equal to one 10-yuan piece of RMB?

How many 5 yuan bills are equal to 10 yuan in RMB?

10 yuan of RMB is equal to 1 piece of 5 yuan plus how many pieces of 1 yuan?

Know the names of vegetables

★There are many vegetables in the vegetable supermarket. Which ones have the children eaten? Have you ever eaten this dish? What is its name? (Introduce the names of vegetables, let’s talk about them together at the end, in order: eggplant, bitter melon, potato, purple cabbage, pumpkin, spinach, carrot, cucumber)

Practice addition and subtraction of numbers within 10

★What’s your favorite dish here? Do you know its price?

★The teacher is going to test you to see if you can complete the grocery shopping task.

Now I want to buy a purple cabbage. If you are a salesperson, how much will you charge? I gave you a 10 yuan bill, do you still need change?

Now I am a salesperson and you are a customer. If you want to buy a cucumber and a bitter melon, how much do you need to pay me in total? You give me 10 yuan, do I need change? How much do I need from you…

Grocery shopping activities

★Congratulations on passing the test, now it’s time to go grocery shopping. The salespersons in the supermarket are too busy. Each group needs one child to be a salesperson to help sell vegetables and collect money, and the other 4 children to be customers to help the teacher buy vegetables.

★The teacher gives each customer 10 yuan to buy the dishes you like. After each vegetable selling activity, team members take turns as salespersons.
