1. Gamification learning: Let children learn mathematical concepts in play through mathematical games and toys. For example, using teaching AIDS such as building blocks, puzzles and counting cards, children can understand mathematical concepts through practical operation.

2. Visual-assisted teaching: Use graphics, charts, images and other visual AIDS to help children better understand mathematical concepts. For example, use color charts to show the relationship between numbers and quantities, or use pictures to illustrate addition and subtraction operations.

3. Storytelling teaching: By writing interesting mathematical stories, the mathematical concepts are integrated into the stories to stimulate children's interest in learning. For example, write a story about the number of animals and let children solve the problem by counting the number of animals.

4. Mathematics in daily life: connect mathematics with children's daily life and let them apply mathematics knowledge in real life. For example, let children help count money when shopping, or let children help measure the weight and capacity of ingredients when cooking.

5. Creative thinking: Encourage children to think creatively in mathematics and let them solve mathematical problems through their own imagination and creativity. For example, let children design their own math games or solve some interesting math problems.

In short, a good way for children aged 4-6 to learn mathematics should be interesting, interactive and practical. Through games, visual teaching AIDS, story-telling teaching, mathematics and creative thinking in daily life, children can be helped to build their interest in mathematics and understand basic concepts.
