With the development of the spring theme, the games in the jigsaw puzzle area of our class have also brought some fresh blood. For example, games sorted by rules in the spring background have attracted the curiosity and attention of many children. At first, in the activity area, children simply put pictures on it, such as butterflies flying in the air, flowers and young trees growing on the grass. I didn't find the secret of sorting according to the law, so I stepped in and reminded him, "You found him the location of butterflies, flowers and grass, but they had to line up like children. Butterflies say they want a pink butterfly and a blue butterfly. You can try it. " The children nodded in a line of butterflies, so I continued to train them in variants, one tree and one flower, and let them operate again. After initially perceiving the order of the rules, I struck the iron while it was hot and asked them to try to describe how butterflies lined up in a language. How do small trees and small flowers stand in a row? Guide children to make language induction through observation and operation, so as to further experience the significance of regular sorting.
With the understanding of the regular ranking level of children in the activity area, I chose to take out this puzzle game to explain to all children in the next evaluation session.
First of all, we should guide children to observe the way different pictures line up, and we must describe them in our own words in order to get a preliminary understanding of the concept of law; Followed by hands-on operation. I give the sorting rules of ABAB and ABB respectively, guide the children to continue sorting after observation, and then talk about why this is the case. What pattern did you find? At this time, some children expressed their feelings: "It's really simple", so I followed their words, and then the teacher made a somewhat difficult rule to see if you could challenge success. So, I put an ABC-style rule on the whiteboard, and the elements increased and the difficulty increased. The children are all thinking seriously after reading it. Xiaoman raised his little hand, put a blue butterfly on it correctly, and successfully found ABC law.
I kept asking, how did you find the pattern? Xiaoman told me, "Line them up in two rows, one by one, and no one holds hands with the blue butterfly." So I asked Xiaoman to demonstrate it himself, and all the children understood this method of finding the law.
After the children give positive and correct answers, I will continue to expand. You can use your little brain to think about how to change the formation for them and form different teams. Then I made a simple summary of the meaning of the law. "What is the law? Just like our children are waiting in line, a boy and a girl are another boy and a girl, or like a red and green signal light, the yellow light is on behind the green light, and then the red light is on. Wait and wait, the green light is on again. In our life, you can guess what will happen next by observing. This is a daily - happened thing. We can talk to our parents.
Piaget said: The concept of number is the sum of two relationships established by children between things, one of which is the sequential relationship, which is the preparatory stage before children learn mathematics. It is an important cognitive skill for small-class children to discover the rules and master the ability to sort according to the rules. We create various games under different themes, hoping that children can learn a lot from them and develop their mental skills.
