Activity objectives:
1. Try to use 3-4 kinds of objects for interval sorting.
2. Explore the law of interval sorting.
3. Pay attention to listening to and accepting various sorting methods and strategies among peers.
Activity focus: use 3-4 kinds of objects at intervals to sort.
Activity difficulty: be able to master the law of interval sorting.
Activity preparation:
1. Teaching AIDS: pictures or objects arranged in spaced patterns, door curtains made of three kinds of fruit leaves alternately arranged, several people with three patterns of phoenix tree leaves, ginkgo orchard leaves, maple leaves and willow leaves, transparent glue and a bottom plate with double-sided adhesive tape.
2. Children's books include animal picture cards, page 7, Wearing Necklace Base, page 13, physical cards, digital cards and symbol cards, page 15, physical cards, page 27, split vest and page 28, On-off and On-off (I).
Activity flow:
(1) Observe and appreciate the laws in daily life.
1. Guide children to observe and appreciate pictures and objects with spaced patterns.
Teacher: What are these? (Regular arrangement of two patterns) How are these patterns arranged? What are their rules? Help children to sum up the corresponding rules 12 12, 122,12, 12 1 etc.
2. Guide children to migrate their experiences in life.
Teacher: Where else have you seen objects arranged regularly? Ask children to discuss and talk freely. Teachers and children record the rules of how to shoot.
(2) Observe the physical curtain to find out the arrangement rules of objects.
1. The teacher showed that three kinds of objects are regularly arranged alternately to form a door curtain.
Teacher: What are the curtains made of?
2. Guide children to observe and say the rules of object arrangement (ABC, ABC).
Teacher: How are these three objects arranged?
(3) Try to use three leaf types for interval sorting.
1. Teacher: There are three modes. What patterns are they?
2. Partners exchange their own arrangement methods.
3. Teacher-child discussion: Can you design a beautiful necklace with these three patterns? How to arrange the three leaves in order?
4. Let each child try to classify three kinds of objects at regular intervals.
5. Guide children to discover the rules of interval sorting.
Teacher: How are these three objects arranged at intervals?
Discussion: Are there other different methods for interval sorting? How should I arrange it?
(4) Children's group operation activities.
1. Complete the leaf necklace.
Teacher: Please make a beautiful leaf necklace with three kinds of leaves arranged neatly.
2. Complete the fruit necklace.
Teacher: Please arrange 3-4 kinds of fruits in an orderly way into a beautiful fruit necklace.
3. Complete the connection with Apple.
Teacher: Connect the apples on the left and right sides with a line, so that the number of apples in each row is five.
(5) Activity evaluation:
Show the results of children's activities and guide children to learn different strategies from each other.
Activity expansion
Provide a variety of patterns in the math area, and let children sort with 3~4 patterns at intervals.
This kind of kindergarten activity allows children to correctly understand the differences between various objects, exercise their thinking logic and give full play to their infinite imagination. This kind of activity can be carried out not only in kindergartens, but also when parents have time to accompany their children at home.
