1, learn to count backwards and forwards, learn to count backwards and forwards.

2. Perceive the law of reciprocal and ordinal number in the game and develop children's thinking development.

3. Emotionally, children can take the initiative to learn in a happy mood, experience the happiness of mathematics activities and feel the fun of collective activities.

Focus of activities:

Understand the inherent law of ordinal number and reciprocal.

Activity difficulty:

Learn to count backwards and backwards.

Activity preparation:

1, courseware Making PPT courseware in kindergarten

2, a children's operation board.

Activity flow:

First, learn math from three little pigs.

1. Today, three little pigs are going to tell the children an interesting story that happened when three brothers were playing hide-and-seek. The teacher tells the story of "three little pigs playing hide and seek" with courseware. )

2. Summarize the interesting mathematical events in the story. The boss will not follow the ordinal number and reciprocal within 10, let alone the ordinal number and reciprocal within 10.

Second, please cooperate with the courseware Counting Apples to learn the ordinal number and reciprocal within 10. Teacher's summary: ordinal number is the number starting from the smallest number, for example, the first number is 1, and the method of ordinal number is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and the reciprocal is the number from the largest number to the smallest number, for example, the first number is/kloc.

3. Appreciate the nursery rhyme "Let's Count Houses Together", and consolidate what you have learned by appreciating and singing nursery rhymes.

Fourth, children's operation activities.

1. Mother pig told the little pig to go home for dinner, but a bad fox crouched beside the little pig's garden and wanted to eat their three brothers. Mother pig arranged a maze of roads in the garden, and only by taking the right road can she go home. On the road on the right, the numbers are 10, 9, 8, 7 ... expressed by reciprocal method. Please connect all the figures with a pen to help the pig go home.

2, children's operation, teacher tour guidance.

3. Praise the children who finish quickly and well.

Verb (abbreviation for verb) game activity.

The flop solitaire game: the teacher opens a card (such as red 6) by counting backwards. The children holding the red number 6 should immediately stand up and say "6" loudly, while the children holding the red numbers "5", "4", "3", "2" and1"are connected in turn and asked to say their numbers loudly.

Sixth, the application of ordinal reciprocal in life.

1, the number sequence displayed when the elevator goes up and down the stairs; Traffic lights; Microwave oven, etc.

2. Show the courseware "Countdown to Happy Summer Vacation", let the children count how many days are left before the summer vacation today (follow the marked calendar and count with the whole class), and the number is "7" to guide the children to think. Today is over. How many days are left tomorrow? How many days are left the day after tomorrow? How about the day after tomorrow? Let the children understand the application of reciprocal method in calculating important days.

Seven, the end

The teacher drew a "hopscotch" grid in the class activity hall, and the children can play "hopscotch" together by counting back and forth after returning to class.
