Middle school mathematics education activities 1 teaching objectives;
1, cultivate children's good operating habits of cooperative and orderly operation.
2. Cultivate children's observation and comparative judgment.
3. Guide children to learn to compare heights, know that heights come from comparison, learn to compare heights on the same height plane, and sort objects according to heights.
Teaching preparation:
1, one set of operation information for each person (big mineral water bottle, small mineral water bottle, coconut milk bottle and Wangzi bottle).
2. Set the performance situation in advance.
Teaching process:
1, guide children to learn to compare the heights of two objects on the same plane.
Set the performance situation. Please compare the height of two children. A is standing on the floor, and bilibili is in the chair. Question: Who is tall and who is short? Can this compare with height? Why? Encourage children to fully discuss.
The teacher concluded: when comparing heights, two people must stand on the same plane and at the same height, so as to compare who is tall and who is short.
Children demonstrate the correct height comparison method.
2. Guide children to find that height comes from comparison.
Ask a child who is shorter than the first two children to come up and compare with them. Q: Why do you say the child is short and tall? Is he short or tall?
Guide children to observe and think and draw the conclusion that whether a person is tall or short depends on who he is compared with.
3. Guide children not to be affected by the size and shape of objects, and classify them according to the height of objects.
Explanation: One day, several bottles quarreled together. They want to go out for a walk, but they don't know how to line up. Now, please ask all the children to help them line up. When they line up, tell us how you lined up for them.
4. Children can further experience the height at which objects are compared through their own participation.
Play the game of "height is higher than height": divide the children into several groups, select the children in each group, and then send them out to compete, select the children in the whole class, award medals, and encourage the children to eat more food and exercise more, so as to grow taller.
Teaching expansion:
Guide children to observe kindergartens' houses, trees and sports equipment, and compare their heights.
Middle school mathematics education activity teaching plan 2 activity goal
1, review and consolidate the characteristics of various graphics.
2. Develop children's spatial imagination and creativity through hands-on operation.
3. Cultivate children's interest in math activities.
Activities to be prepared
1, ppt courseware-all kinds of graphics
2. Interesting exercises and graphic card games.
3, wonderful box, all kinds of graphics cards.
Activity process
First, the game: find a graphic doll in the "wonderful box"
1, show me the wonderful box.
Teacher: Today, the teacher brought a wonderful box. Do you want to know what secrets are hidden in it?
2. The teacher reads children's songs: There are many things in the wonderful pocket. Let me touch it first and see what it is.
Take out the rectangle
Q: What is this? Why do you say she is rectangular?
In our daily life, what things are rectangular?
(Guide the children to discuss)
3. Read children's songs again: There are many beautiful things in your pocket. Please touch so-and-so children.
When children touch a graphic, they are required to tell the name and characteristics of the graphic. What other such items are there in life?
The game is repeated.
4. Teacher's summary: There are circles, triangles, squares, rectangles, trapezoids and ellipses in the wonderful box.
(1) A triangle has three angles and three sides;
(2) A square has four sides and four corners, the four corners are equal in size and the four sides are equal in length;
(3) A rectangle also has four corners and four sides, the four corners are equal in size and the two opposite sides are equal in length;
(4) A trapezoid also has four sides, two opposite sides are parallel sides, and two oblique sides are beside it;
(5) Both a circle and an ellipse are round and have no corners. The edges are smooth to the touch, but the ellipse is flat.
Second, collage
1, Teacher: Children are really capable, so the graphic doll wants to play a game with us.
There are many graphic babies on the plate. Please choose your favorite graphics later and add a few strokes to them to turn them into other interesting items.
You can also use several graphics to make various other items. Let me see which child is the cleverest and changes things differently from others.
2. Inspire children to imagine boldly and add another object to the geometric figure.
3, the game-graphic card game.
Third, counting and sorting activities.
(According to the number and type of your own pictures, make statistics and classification on dolls. )
1, please tell some children: What graphic baby did you use to change it? Into what?
2. How many things have you changed with the round one? Who has changed the most (the most obvious performance)
3. Triangle, square, rectangle, trapezoid and ellipse are arranged in sequence.
Mathematics education activity teaching plan 3 junior high school classroom activity goal:
1, and the equivalent objects can be taken out according to the specified number within 5.
2. Children can observe and compare the same number of objects through vision.
3. Be able to initially negotiate and share materials with peers.
Activity preparation:
1. Make the activity room a supermarket. A set of smiling envelopes 1-5 and 1-5 physical cards.
2. The child has a small basket with a small card in it.
3, according to the number of smiling envelopes, physical cards.
Activity flow:
First, activity import.
1, each child carries a small basket with a card in it.
Teacher: "children, we are going to visit the doll house of big brother and big sister later. Let's go to the supermarket first."
Do you want to buy some gifts in the city? Everyone can buy three kinds of gifts. How much is each gift? Look at your basket.
Buy as many cards as you want. "
Children go shopping in the supermarket. Take out the same number of objects according to the card.
3. Teacher: "My brothers and sisters called and asked you to bring a small card to their smiling envelopes. we
Let's look at the smiling face doll on the envelope first. Then find a card friend for it. It's just that there is a baby face on the envelope.
Only the same number of cards can be put in the envelope. "
Let a child demonstrate the operation and put small cards according to the number of baby faces on the envelope.

(2) The five children are sorted from high to low.
Teacher: Now they are all on the same level. How to arrange them?
First find the highest, then find the second highest behind the highest, and then find the third highest next to the second highest. ......
Teacher: Xiaoxiao and Zuo Zuo look almost the same height. What should we do?
Let them stand on the same level first and stand at attention, or let them stand back to back without looking up at who is taller.

(3) Children check and discuss with each other.
Activity reflection
Mathematics comes from life. Let mathematics help us solve problems in our daily life. Make use of common things in life, gradually enter the topic from the shallow to the deep, thus mobilizing children's enthusiasm for learning and promoting their subjective development. Mathematics "queuing" is an activity of queuing according to the law. Let children experience the fun of operation in operation activities.
Queue up regularly for the first contact. Usually children find it more difficult. According to previous teaching experience and children's age characteristics. Queuing is a daily thing for children to get close to life. Let the children personally participate and feel that the sorting is regular. At the end of the operation, the children did very well.
During the whole activity, children study in a relaxed and pleasant atmosphere, and the classroom atmosphere is active, so children are better at queuing according to the rules.
