Lesson 1 Math Statistician in Kindergarten Junior Middle School Class I. Purpose of the activity:
1. Have a preliminary understanding of simple statistical methods and apply them to real life.
2. Dare to try and explore, learn classification and statistics, and be able to perceive numbers through charts.
3. Guide children to record the process and discovery of exploration with paintings and simple charts.
Second, the activity preparation:
1.4 small shelves and some commodities (such as stationery: watercolor pens, pencils, tablets, daubing pens; Tableware: cups, plates, bowls and spoons; Food: candy, bread, robust milk, milk; Fruits: apples, pears, bananas, grapefruit; Quantity less than 10, packed in baskets).
2. A child's hand: a game stick, a triangle, a basket of disks (the number is within 10 respectively), a watercolor pen, 1 piece of white paper, 1 piece of statistical table, a statistical table, a splint and a statistician's signboard.
3. 1 magnetic blackboard and 1 large statistical table; New Year stage scene layout (1 Chinese knot, 8 lanterns, 2 dolls, 4 waist drums); There are 1 old people in the New Year, and some gifts;
Third, the activity process:
(A) try to explore statistical methods
Set suspense and let the teacher test the children with mysterious guests. Please write down the number of game sticks, triangles and disks in your basket on white paper in your own way and try statistical methods.
Teacher: (in a mysterious tone) Children, I have good news for you. A guest you like very much will come to play with you. Do you want to know who it is? I won't tell you first, but he wants to test the children in our class to see if you can clearly count the number of various items in the basket and record them neatly and clearly on white paper. Then he will come and play with us. Do you want to see him? Then let's act quickly.
(B) a preliminary understanding of statistical methods.
(1) Discussion: How did you record it? And show representative children's works (including picture recording, picture plus digital recording, etc.). ) one by one, and the teacher properly evaluates the advantages and disadvantages of the children's recording methods. Finally, form records are displayed to illustrate the advantages of form records (neatness, clarity and easy comparison)
(3) Game: Small Statistician
(1) Let the children organize the goods in the small supermarket for the old people who celebrate the New Year in groups, and record the quantity of all kinds of goods on the shelves on the statistical table with the sketch of goods (see statistical table 1).
Teacher: Well, we have finished the task of this mysterious guest. Let's count 1, 2, 3, and he will come. Who is he?
New year's old man: the child is very capable and will really find a way. I'm opening a small supermarket, children. I just bought so many goods. Can you help me? Help me tidy up and count these goods.
Teacher: Are the children willing? Then let's act in groups. Be sure to help the elderly in the New Year put their belongings in order and record them clearly.
(2) Records of children's group inspection results.
(3) Send a child from each group to report the recorded results to the old people in New Year.
(4) Teacher's summary. On New Year's Eve, the old man gave the children the sign of "Little Statistician".
(d) Situational game: counting the items on the small stage of the New Year.
(1) Let children count and record the number of various items on the stage, and encourage children to boldly design their own item marks and make statistics with tables. Report the record results to the New Year's old man.
Teacher: The old man invited the children to visit the New Year stage. Come on, let's see. What's there? What shape is it? How to draw if you want to record? Let's count down.
(2) Children can freely count the types and quantities of stage scenery in the blank statistical table (see Statistical Table 2).
(5) Old people distribute gifts on New Year's Day. The activity is over.
Self-evaluation of activities: In the process of guiding children's learning, I try to break away from the previous mathematics learning of children, which is mainly based on watching and listening, and the operation is mostly to verify the knowledge taught by teachers; Break children's consciousness that "teachers are the source of knowledge" and "teachers are the embodiment of truth", so that children can face the truth directly, touch the truth, explore and solve problems, and really get in touch with mathematical knowledge. In the process of children's exploration and attempt, we try to make children need to use mathematics to solve problems and practice, discover and learn mathematics by themselves through real problem scenarios. Children's enthusiasm in activities is very high, and they repeatedly experience the fun and significance of statistics in very real-life situations.
Teaching Plan for Small Statisticians in Kindergarten Middle School Part II Activity Objectives:
Learning statistics table counts the number of graphics according to two characteristics of graphics.
Let children learn simple math problems.
Develop children's observation and spatial imagination.
Activity preparation:
1. Various geometric graphics cards.
2. Elephants, birds, fish, turtles and pictures.
3. Statistical chart 1, figure 2, pencil.
Activity flow:
Teacher 1: Small animals came to play games with us today. Look who's here (fish, birds, chickens). What secrets are hidden in these little animals? What graphics are used (all made of graphics)? How much did you use separately?
Second, learn to count the number of geometric figures with statistical tables.
1. Show pictures of turtles. The children tried to record the numbers of each figure in various ways.
2. Show the statistics table (Figure 1) to guide children to learn to count the number of each pattern in turtle patterns according to the order and method from top to bottom or from left to right.
Children try to record the figures of the shape and color of the tortoise in various ways.
4. Show the statistics table (Figure 2), and learn to count the number of figures in the tortoise pattern by shape and color.
Summary: Just now, we learned to count the number of tortoise figures with statistical tables. Watch carefully when counting, counting from top to bottom or from left to right is not easy to make mistakes.
Third, children's operation, you can use statistical tables to count the number of graphics according to their shapes and colors.
Provide each group of children with 3 pictures of small animals and statistical tables (Figure 2), and children can choose their own pictures for statistics.
Fourth, teachers and children jointly test the statistical results.
Five, the end.
Teacher: Today, the children did a good job. We have learned to use statistical tables to count figures by shape and color, to observe them carefully with small eyes, and to observe them in an orderly way. The teacher also has some graphics and pictures, which children can put together by themselves and count with statistical tables.
Activity reflection:
This is a math activity in a big class. There are 30 children in this activity, divided into three groups, each group has 10. In the first step of importing pictures, animals are composed of different shapes of graphics, the outer border of each graphic is a ditch with different colors, and the graphic itself is white, so that each graphic can be clearly observed visually. At the beginning of the activity, the children developed a strong interest. Whenever there are several figures, the children are scrambling. Some children stretch out their fingers, others stand up and strive to be the first to tell the answer. Speaking of operation, children choose a picture for statistics according to two characteristics. It embodies children's autonomy and meets their different needs. In the operation, the children carefully observe the statistics, because the pictures provided are all children's favorite patterns, such as robots, little princesses and so on. Finally, when I tested the results with my children, some children were still looking down. It can be seen that children like this festival very much. Everyone's interest in participating is very high, and finally all the statistics are finished. Although some children's statistical results are wrong, when they learn that the numbers are missing, the children's faces are serious and bright, so beautiful.
