Mathematics enlightenment is contained in family life and is everywhere. It forms a sense of numbers from objects, from 1 to 3, slowly from 4 to 6, and finally from 7 to 10. Don't use your quick wits, start with the scenery, as long as your parents have this awareness, and then form a sense of addition and subtraction from the real thing. For example, how many sweets are one candy and two candies? How much is three apples MINUS one? The final reading is 1 to 100. Try to make a graph. Finish it before school. Children will be stimulated if they are interested. If you are not interested, you will force it, and you will moisten things silently. Be careful not to write numbers in a small notebook with paper and pencil, and add and subtract these empty things. Parents can sometimes stimulate them to see if they can do well, which is a test for their parents.
