Activity objectives:
1, experts can count six or seven items in unison and tell the total.
2. Perceive the formation of numbers 6 and 7 and the practical significance they represent, and know numbers 6 and 7.
3. Improve the agility of children's thinking and be curious about numbers.
4. Guide children to actively interact with materials and experience the fun of mathematics activities.
5. Stimulate children's interest in learning.
Activity preparation:
1, teaching aid preparation: "digital card"; "Black, white and gray beads".
2. Preparation of learning tools: "Digital guest films."
3. Operation Manual Volume 3 Page 9- 10.
Activity flow:
1, preheating activity.
Teachers and children greet each other.
Online game: driving a train. Drive the train to the rhythm of the music. If the pace is fast, the train will go fast. When the pace is slow, the train is slow. At the end of the game, let the children guess: it is a flower without race, with six petals in the air.
The north wind sent it to the ground, and the ground and trees were white. (snowflake)
2. Group activities.
(1) The formation of learning 6.
The teacher asked the children to take out "black, white and gray beads". First, take out black beads and let the children count them. One * * * has five. Then take out six beads and let the children change stubble. What's the difference between this bead and five beads? (There is an extra white bead. ) Count how many beads there are on this rope.
Summary: 5 plus 1 is 6, 6 is more than 5 1, 5 is less than 6 1.
(2) The formation of children's own operation exploration.
Children take out seven black, white and gray beads, count how many beads there are, and then compare them with six beads. It is concluded that 6 of 1 is 7, and 7 of 1 is greater than 6, so as to understand the formation of 7.
(3) Read the numbers 6 and 7.
Teacher: "Six monkeys and six peaches can be represented by the digital baby" 6 "in the digital kingdom. 6 is like a whistle, with a big belly and a long neck; Seven rabbits and seven carrots can be represented by the number "7", just like grandpa's crutches. "
3. Operational activities
Complete the activities in volume 3 of the operation manual,No. 9- 10.
Activity expansion:
Sports games "change", children quickly form a group according to the numbers spoken by the teacher, forming various shapes. For example, six people make up a flower and seven people make up a gourd doll.
Activity Tip: In teaching, we should pay attention to gradually abstracting the concept of number through various objects, so that children can initially realize that a number can represent the same number of any object.
Mathematics in life
1. Complete the activities in Book III,No. 17-20.
2. Use calendars, clocks and other items with numbers to let children read the numbers 6 and 7.
