1, using physical objects to teach: using physical objects to help children understand the concept of addition and subtraction. For example, taking some balls or beans and moving them a little at a time can help children understand the meaning of addition and subtraction.

2. Combine life examples: apply addition and subtraction to daily life, such as calculating the total price when shopping, and calculating the number of each share when distributing items. This can help children understand the application of mathematics in daily life.

3, using graphics: you can use graphics or fingers to help children count and calculate. For example, use fingers to represent quantity, and let children understand the change of quantity by counting fingers.

4. Step-by-step guidance: Start with a simple one, first teach children the addition and subtraction within 10, and then gradually increase the difficulty to less than 20. At the same time, children should be encouraged to think and solve problems by themselves.

5, interactive games: design some interesting interactive games to help children learn. For example, make some numbered cards for children to add and subtract, or exercise children's computing ability through games such as guessing numbers.

6. Encourage a positive attitude: Encourage children to have a positive attitude towards mathematics and make them feel that learning mathematics is very interesting. At the same time, let them understand that learning mathematics requires constant practice and thinking.

7. The role of parents and teachers: Parents and teachers play a very important role in this process. They need to actively communicate with their children, understand their learning progress and difficulties, and provide help and support in time.

Ways to improve children's mathematics learning ability;

1, cultivate interest in learning: interest is the best teacher. Parents and teachers can stimulate their children's interest in learning in various ways, such as letting them participate in interesting learning activities, encouraging them to try new things, or letting them know the significance and value of learning.

2. Provide a good learning environment: Children can improve their learning efficiency in a quiet, clean, well-lit and well-ventilated environment. Parents and teachers can provide suitable learning places and necessary learning tools and materials.

3. Make a reasonable study plan: help children make a study plan and arrange time reasonably to ensure that children have enough time to complete tasks and study. At the same time, let children know the importance of the plan and encourage them to implement it consciously.

4. Cultivate good study habits: Good study habits are an important factor to improve learning ability. Parents and teachers can guide children to develop good study habits such as regular review, taking notes and reading.

5. Encourage independent thinking: let children learn to think and analyze problems independently, and encourage children to put forward their own ideas and opinions. This helps to cultivate children's innovative thinking and problem-solving ability.
