Children's mastery of knowledge is acquired through self-exploration and hands-on operation. The outline also points out that we should feel the quantitative relationship of things from life and games and appreciate the importance and interest of mathematics. So I choose to know RMB, which is indispensable in our life, so that children can understand the characteristics of 1 yuan, 5 yuan and 10 yuan by watching, speaking and using it.

Speaking of activity goals: Set goals from two aspects according to children's age characteristics and cognitive characteristics.

1, knowledge and skills-know three denominations of RMB, be able to correctly identify three denominations of RMB, and be able to buy goods at corresponding prices with coins.

2. Method and process-let children know the function and role of RMB in commodity exchange through games;

RMB is the legal tender in China and plays an important role in people's lives. Understanding RMB is the key chapter of large class mathematics. Learning RMB helps children understand the knowledge and usage of RMB and improve their social practice ability. Modern educational theory advocates that children should "do" mathematics and create practical opportunities for them in teaching. I will make full use of the children's experience in designing this class and design this kind of learning into children's practical activities.

Teaching emphasis: understanding three teaching difficulties of RMB with face value: the teaching method of correctly using RMB to buy goods at corresponding prices;

Children's mathematics learning should be completed in mathematics activities, and the ultimate goal of children's knowledge is application. The knowledge and experience gained through one's own practice are the most valuable, and the methods obtained are the most effective. Therefore, through the game of exchanging items with coins, children can realize the fun of knowing RMB and experience the importance and interest of mathematics.

Activity flow:

I designed four links in this class:

In the first part, I prepared three kinds of coins (1 yuan, 5 yuan, 10 yuan). After showing it to your child, please find a way to quickly distinguish coins by observation. This part is mainly about the understanding of coins, so that children have a preliminary impression of these three coins.

The second link is a small game, through which children can be further familiar with coins;

In the third link, I prepared a lot of toys, the prices are 1 yuan, 5 yuan, 10 yuan. In addition, I also prepared three kinds of coins for each child, so that children can use coins on the basis of the first two links. Please use their coins to buy their favorite toys. This link requires children to know the face value of coins before they can buy their favorite toys. This is mainly a consolidation process, and children can experience it in this link.

The last link is the summary, to let children know that there are many denominations of RMB, and there are other kinds. Coins are very important in our lives. The whole class is in the form of games, so that children can "play" and "do" middle school.
