This book first introduces how numbers are generated from things. With the development of productive forces, people gradually need to make some things clear. So numbers are indispensable everywhere. People in primitive tribes thought it was unlucky to count their cows, so they used some pebbles instead of cows. Replacing what you want to count with stones or other things is a mathematical "pairing". The book introduces the idea of "one-to-one correspondence" in mathematics with the story of counting cows. Understand "as much", "more" and "less". I also introduced the math symbol "=" to the children.
We realize the importance of "pairing" in the game by playing a game of "grabbing chairs". A child said, "If you don't have to grab chairs as long as people do, the game won't be fun. If there are fewer chairs and I need to grab them, I will feel a little excited. This game is very fun. "
The last part introduces how these numbers are named. For example, in some languages in the world, the pronunciation of "2" is similar to that of "ears" or "eyes". Sure enough, the pronunciation of "ear" is close to 2, and the pronunciation of English eyes is close to 2 and. This may be because in ancient times, people used their ears or eyes to refer to 2 when they said 2. Here is a special introduction to "5". In some national languages, 5 is the same word as "hand". Indians in the early American west drew five fingers and a tree, which means there are five trees. At the same time, it also infiltrated the counting methods of "binary", "pentad" and "decimal".
After class, I encourage kindergarten children to count with their own hands. Always count your fingers and index what you want with your hands, not things. This is very helpful for children to learn math.
Hanson Mathematics is a very good picture book of mathematics. Reading picture books will make different people have different gains.
