Small class mathematics color marking teaching plan 1 activity goal
1. Know the color signs of red, yellow and green.
2. Learn to classify objects according to color marks.
3. Be willing to participate in mathematics activities and be able to operate boldly in the activities.
4. Stimulate children's interest in learning.
5. Let children understand simple mathematical principles.
Activities to be prepared
1, teaching AIDS: red, yellow and green marker, three houses, three rabbits, red, yellow and green radish.
2, learning tools: children's operating materials, paste, pencils, rags.
Activity process
First, group activities.
1, know the color label.
Teacher: Look, children, here are three cards. What color are these cards?
(red, yellow, green)
Teacher: The teacher gave these cards a nice name.
Inspire children to know: red label, yellow label and green label. Ask individual children to read, and finally the teacher will lead the children to read the names of these three marks.
2. Learn to classify by color code.
(1) Teacher: Look, children, everyone has come to our classroom. (Little Rabbit) Today, Little Rabbit wants to tell us a good news. It will move to a new house. Let's have a look at Bunny's new house.
Show three color-coded houses.
Teacher: What color is the brand of Bunny's house? (Red, yellow and green) The teacher and the children say the three color signs on the house together.
(2) Show three rabbits and guide children to observe the colors of the three rabbits.
Teacher: What colors are these three rabbits? What color house should they live in? Who wants to take them home?
Tell the children to come up and take the rabbit home. The teacher guides the children to say together: the red (yellow, green) rabbit lives in the home marked red (yellow, green).
(3) Send radishes to rabbits.
Teacher: The rabbit is hungry. Let's pull out some radishes for rabbits.
Children and teachers pull radish together, and guide children to tell what color radish is. Finally, let the children send the radish to the corresponding rabbit home. Hair said: Red rabbits eat carrots. ...
Second, children's operational activities.
Teacher: The teacher also prepared many small numbers for the children to send back to their homes.
Children's operation activities, teachers watching and traveling, focusing on guiding children with weak ability.
Third, activity evaluation.
Give praise to the children who do their homework conscientiously and boldly.
Reflection:
Children actively participate in the whole teaching process and express their feelings in immature language. Because children talk more, the time of the whole activity is relatively prolonged.
This article extends reading: color is the visual perception of light through eyes, brain and our life experience. The light we see with the naked eye is produced by electromagnetic waves with a narrow wavelength range. Electromagnetic waves with different wavelengths show different colors. The recognition of color is the visual nerve feeling produced by the naked eye under the stimulation of electromagnetic wave radiation energy.
Small Class Mathematics "Color Marking" Teaching Plan 2 Activity Objective:
1. Let children know to classify objects according to certain characteristics.
2. Learn to do color coding.
Activity preparation:
Six teaching AIDS, two colors (3 red and 3 green). ), 2 squares, colored pens, cardboard production. The first and second groups of learning tools: 1 plate of tricolor flowers (3 red, 4 green and 3 blue). ), each person 1 calculation box, several colored pens and several pieces of cardboard. The third group: one set of graphics (see Figure 2), each person 1 calculation box, each person with 6 marks of size, shape and color, and operation cards 2 and 3; The fourth group: plastic animals 1 set (3 species, the quantities are 1, 2, 3 respectively. ), each person counts 3 cards (the numbers are 1, 2, 3 respectively. ), calculation box 1, operation card1l; ; The fifth group; There are/kloc-0 sheets of material paper and physical cards (4 sheets, see Figure 3). ), operation card 13.
Activity flow:
1. Group activities.
(1) classified by color characteristics.
Show me the disc, "What's here? What is the difference between the two? " Show me two squares. "These two houses are pieces of home. Who will send the fragments home? The same parts should live together. As I saw it off, I said, "I'll take you home and live with you." "Please ask some children to operate on the velvet board." Who can tell me what chess pieces live in these two houses? " (Red patch, green patch. )
(2) Learn to do color coding.
What kind of signs do you want to put on each house to show which land you live here? "Refers to red patches and green patches." Who will make this mark? "Help some children to color the cardboard with red and green pens (see figure 1)." What is this mark? To whom? What do you mean? "
2. Group activities.
The first group and the second group mark flowers.
"Put flowers of the same color together and see what color they are. At the same time as sending the bid, you should say: I will send you the bid of any color for the flowers. "
The third group, send the film home.
"Put the same pieces together, and then find out the marks of these pieces. When you send the tag, you say, I will give you any color tag. "
The fourth group, send some cards to animals.
"First put the same animals together, line up according to the number of each animal, and then send some cards to the animals, saying: How many animals send some cards?"
Group five, line up the cards.
"Say first how the cards in front of the material paper are arranged. Who should line up next? The cards are arranged, and let's talk about how the cards go from front to back. "
In group activities, the teacher focuses on the activities of the first and third groups of children.
3. Activity evaluation.
(1) Show the color codes made by individual children and comment on the correctness and coloring methods.
(2) Encourage children who speak loudly about the contents of the operation.
