Start with life, such as "You have an apple, I gave you one, and how many do you have now". Children's golden education period is from zero to six years old, I hope to grasp it well.

You can also educate children in life. When you encounter some small things, you should take good care of them and induce them. Never scold them loudly, it will make them lose interest. Remember, all children's success comes from interest. You should make children fall in love with mathematics, and then teach them well and induce them. I believe your child will become a math genius.
