2. Infiltrating mathematics through number recognition is inseparable from real life.
3. Stimulate students' interest in learning.
Teaching Emphasis: Writing of 6, 7 and 8
Teaching difficulties: the meanings expressed in 6, 7 and 8.
Teaching process;
First, courseware import
(1) Picture (Beautiful campus and students jumping rubber bands and playing slides on campus. )
(2) (Guide students to look at pictures, talk and count) How many things do they stand for?
Second, explore new knowledge.
1, abstract number
There are many things in life that can be expressed by 6, 7 and 8. Please choose your favorite way to put them on the table, find them and tell everyone.
② Students' hands-on operation: it can be indicated by fingers, placed in a disk or triangle, and placed in a digital card. Sticks, apples, peaches, chickens and so on.
③ Student report
④ Summary: 6, 7 and 8 are abstracted.
2. Learn the relationship between 6, 7 and 8 and the writing of 6, 7 and 8.
Order of (1) numbers
This is an enlarged scale diagram of crushing. (graphic)
Read it. (0—8)
Let's point to the card you put and read it backwards. (8——0)
Summarize the order of 6, 7 and 8. (6 plus 1 is 7, followed by 8.
(2) Compare size
Compare sizes 6 and 7. [Blackboard 6 < 7]
How do you know 6 < 7? Look at the ruler chart, put a disc, count your fingers, etc. )
Who can compare the sizes of 8 and 7? Blackboard 8 > 7
Do you know what is smaller than 7? Please look in the digital card and show it to the people around you.
Name a number greater than 5. [The teacher holds up five cards]
(3) the writing of 6, 7 and 8.
The books of 6, 7 and 8 are empty. How do you remember six, seven and eight?
Note: We wrote 6, 7 and 8 by hand, and 8 was not stamped!
Please open page 30 of the book and write each number twice after drawing 6, 7 and 8.
Student evaluation.
3. Summary: What did you learn from the study just now?
Third, practice.
(1)30/ 1 count.
(2) (P3 1/5) Scale exercise:
[Display: 7 O 4 5 O 8 6 O 6 7 O 1]
How about 7 and 4?
② Students open their books to practice.
(3) Read it and correct it.
(3) What have you seen in your life? The numbers are 6, 7 and 8?
Students give examples. 6, 7, 8 can be seen everywhere in life, and our life cannot be separated from mathematics!
(4)(p 3 1/ Thinking)
65438+ 0 people play on each swing, and 2 people play on each counter. When the swing and the pressure plate are full, is there anyone who hasn't played? Please verify the answer through after-class exercises.
Writing on the blackboard: Tian Ge writes down the positions of 6, 7 and 8 on feet 6, 7 and 8.
Reflection after class: Students have a good grasp of the numbers 6, 7 and 8, and can correctly count the number of objects, the order and size of the numbers, but most students have a poor writing of 8.
