1, physical count: count with physical objects, such as fingers, toys or sticks. This method can help children intuitively understand the concept of quantity.

2, picture counting: use pictures to help count, such as drawing different numbers of objects or patterns. This method can help children understand the concept of addition and subtraction.

3, digital operation: help children master basic mathematical operation skills through simple addition and subtraction operations. For example, you can ask children to count some objects, and then let them use numbers to represent the quantity, or let them use numbers to express some simple addition and subtraction operations.

4. Time perception: Help children understand the concept of time by letting them perceive time. For example, children can perceive the passage of time by observing a clock or an hourglass.

5. Coin cognition: Help children understand the concept of money by letting them know coins. For example, children can be taught different denominations of coins, and they can try simple shopping and change.

The advantages of young convergent mathematical problems mainly include:

1, help children to establish a mathematical foundation: children can help children understand the basic concepts of mathematics, such as addition, subtraction, multiplication and division, fractions, decimals and so on. To lay a solid foundation for the subsequent mathematics study.

2. Cultivate children's logical thinking and problem-solving ability: By solving mathematical problems, children need to use logical thinking and reasoning ability to find ways to solve problems. This thinking process can cultivate children's observation, analysis and creativity, and improve their ability to solve problems.

3. Enhance children's self-confidence: By successfully solving math problems, let children feel their own growth and progress, and enhance their self-confidence and self-esteem.
