How to write the harvest after reading the math picture book?
Today, Dahe Spring Kindergarten of Henan Experimental Branch visited our school. Parents hope to enter the primary school classroom and experience the life of the first grade of primary school. There are more than 40 children in each class this time. What kind of class can let these 40 children study with 28 children in our class? I took a math picture book course and read Han Sheng's How Mathematical Numbers Come from. This book will make different children have different gains and even make teachers think.

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.
