Beijing Normal University Edition Senior One Mathematics Courseware Volume 1
Teaching content:
"About" on page 66-67 of Grade One Mathematics of Beijing Normal University.
Teaching objectives:
1. Through familiar life scenes and interesting activities, make students know the position and order of left and right, and experience the relativity of left and right.
2. Be able to relate to the actual situation in life and describe the left-right relationship of objects.
3. Experience the application of left and right in life and feel the fun of learning mathematics by combining activities such as posing and doing actions.
Teaching emphasis: understand the positional relationship between "left and right" and be able to describe the position of objects with "left and right" initially.
Teaching difficulty: understanding the relativity of "left and right".
Teaching aid preparation: multimedia
Preparation of learning tools: pencil case, ruler, pencil sharpener, eraser and pencil.
teaching process
First, create situations and introduce new lessons.
1. Create a situation and reveal the topic.
2. blackboard writing topic: left and right
Second, contact yourself and experience the left and right.
1. What can your two little hands do at ordinary times?
Find, touch and point.
Find a good friend in your body, touch and point.
3. Action games, I said you have them.
The teacher shouted the password and the students did the action.
Activities from easy to difficult, first in the same direction, and then in the opposite direction.
Third, apply promotion to solve problems.
1. Put a pendulum and say it.
(Question 2 on page 66 of the textbook)
Listen to the teacher and set the stationery.
Organize students to place familiar stationery according to the position relationship between left and right, and experience the relativity between left and right in operation. And answer the questions according to the spread stationery.
Do it and enjoy it.
(Question 3 on page 66 of the textbook)
The kitten is visiting the rabbit's house. How can I get there?
Describe the kitten's walking route with the "left and right" knowledge we just learned and the "up and down" knowledge we learned earlier. See how many roads there are. Choose the nearest.
3. Experience the relativity of "left and right".
(1) Teachers and students face each other.
(2) Sit at the same table face to face
(3) Climbing stairs
(Question 6 on page 67 of the textbook)
Students first think and judge independently, and then ask them to perform to help them understand the relativity of left and right.
Step 4 say and point out
(Question 3 on page 67 of the textbook)
Communicate at the same table and give feedback from the whole class to further consolidate the understanding of the left and right.
5. Draw a picture and say it
(Question 4 on page 67 of the textbook)
Students think independently, try to draw pictures (using only simple symbols) and communicate with the whole class.

Fourth, the class summarizes.
