Compare the equality and inequality of the two groups of objects.

As a diligent educator, you usually need to prepare a lesson plan. With the help of lesson plans, you can properly choose and use teaching methods to arouse students' learning enthusiasm. How to write the lesson plan? The following is a small class math teaching plan that compares the equality and inequality of the two groups of objects for your reference only. Welcome to reading.

Activity objectives:

1, the number of objects will be compared by overlapping correspondence method.

2. The results of the comparison will be expressed in the same amount but different amounts.

Activity preparation:

Plates, bowls, spoons, apples and pears, one small plate for each child; Operating materials for children's activities; Create a dollhouse environment.

Activity flow:

1, introduced in the form of tableware, to stimulate children's interest.

2. Divide the tableware one by one, and learn to compare two groups of objects with the same number by overlapping and corresponding methods.

(1) Observe 3 bowls and 3 questions: Are there as many dishes here? How can we know?

(2) Demonstration: I first set the plates one by one, and then put the bowls on the plates. Only one bowl can be put in a plate, so that the plate and bowl become good friends.

(3) Question: Are there the same number of plates and bowls?

Guide children to express themselves in the same way.

3. Divide the fruits one by one, and learn to compare two groups of overlapping objects.

(1) Observing apples and plates, ask: What's here? Are they as many?

Demonstration operation: First, put four fruit bowls one by one, and let a child stack three apples on them.

(2) Inspiration and guidance: How do teachers compare?

(3) Guide children to express that there are not as many plates as apples, but more plates and fewer apples.

4, children's operation: help pigs wear flowers.

(1) How to play: Put the pig tag in the homework materials on a small plate for each child, and let the children tear off four small red flowers from the small red flower sticker, paste them, compare them and say: Are there as many small red flowers as pigs? Who is more and who is less?

(2) Children's operation and teachers' observation and guidance.

(3) Collective sharing to encourage children to express the results of comparison.

Activity reflection:

There is no certain method to compare the number of children in small classes, and most of them are obtained through intuitive observation. However, it is unrealistic to compare the number of two groups of objects in your mind, or to abstract the number of two groups of objects and compare the size of two numbers, for small class children who think by action and can't even count objects one by one, and the one-by-one sorting method is the simplest and direct method to compare the number of objects. Therefore, in this activity, we let children judge the relationship between more, less and equal amount of two objects through physical operation, which is conducive to children's understanding of the concept of logarithm, which is a key step in the emergence of the concept of children's number. Through activities, children are initially guided to perceive and understand "how much" and "as much", which can be expressed in simple language, thus initially cultivating children's observation ability.

Expanding: Small Class Mathematics Teaching Plan

Teaching objectives:

1, teach children to distinguish between height and height, and initially grasp the relative relationship between height and height.

2. Teach children some simple comparison methods and cultivate their ability of observation, comparison and judgment.

3. Cultivate children's comparative judgment.

4. Guide children to actively interact with materials and experience the fun of mathematics activities.

5. Stimulate children's interest in learning.

Emphasis and difficulty in teaching:

Key points: distinguish between height and height, and learn how to compare height and height.

Difficulties: Understand the relative relationship between height and height.

Teaching preparation:

Three sets of courseware, a piece of cloth, and some objects that can be raised or lowered in daily life.

Teaching process:

First, teach children to distinguish between height and height.

1. Show courseware 1. The picture shows two girls with different living habits, different health conditions and different heights. Let children find out their differences through observation and comparison (introduction of height combined with health habit education).

2. Show the objects one by one, and let the children compare who is tall and who is short.

3. Let two children come up to compare who is tall and who is short, or the same height, and then let all the children compare with each other, who is tall and short, or the same height.

4. Let the children talk about what they are familiar with.

Second, teach children some relatively high and low methods.

1, two children, one tall and one short, please stand on the stool and cover the front with a piece of cloth so that the children can judge who is tall and who is short. When children have illusions, uncover the mystery and tell them to put objects at the same height when they grow taller.

2. Show the courseware 2. In the picture, there is a tree nearby and a tree in the distance. Let the children judge the height of the tree. When a child has an argument, pull back the tree far away, let the child compare it again, and then tell the child to put the object in the same place, otherwise it will be inaccurate.

3. Show the courseware 3. A giraffe is on the ground, and a monkey climbs to the top of the tree. The monkey lowers his head and says to the giraffe, Look! I am taller than you. Question: Is the monkey right? Why?

Third, tell children the simple relative relationship between height and height.

1, please compare two children, one is tall and the other is short. Then let the tall child compare with the teacher or the short child, and let the children know that the tall child is taller than the short child, shorter than the teacher, shorter than the tall child, but taller than the short child. Tell children that a single thing can't be set high or low, it depends on what it is compared with.

2. Let three children come up, and then let a child line them up from high to low, and tell who is taller and shorter, and who is taller and shorter than who.

Give each child a pen and paper, and let each child draw three trees with different heights in turn.

Teaching reflection:

Most children in life have a preliminary understanding of "size", and the teaching goal of this lesson is to let children distinguish the difference between height and height, which is similar to "size", so with the previous foundation, the knowledge involved will not be too wide, so there will be some experience when it is implemented again. It is absolutely surprising that the phenomena revealed by young children are quite general and vague.
