Middle school mathematics 9 teaching plan 1 the formation of activity goal;
1, by guiding children to observe, let children clearly perceive that 1 plus 8 is 9 and can add words.
Describe the formation of learning.
2. Cultivate children's habit of listening carefully and operating carefully.
Activity preparation:
Teaching aid: wall chart (apple tree with 8 red apples and 8 green apples hanging on it) 1 magnetic red apple and 1 big green apple. Number plate 1-9.
Learning tool: snowflake
Activity flow:
First, review the formation within 8.
1, clap your hands.
2. Look at the numbers and act. The teacher shows the number 1-7, and the children make corresponding numbers according to the numbers.
Action)
3. Then say the number (the teacher casually said the number, and the child went on to say it)
Second, the formation of learning 9.
1. Show the wall chart and ask: What's on it? (After the children finish speaking, the collective counting verification can guide the children to count again by visual inspection.) How many can there be eight red apples and eight green apples in numbers? (The teacher gives the matching number 8)
Some apples are covered with leaves. Look at what the apples have covered. (Guide children to say 1 red apple and 1 big green apple).
How many red apples and green apples are there now? How did nine become? (Guide the children to say that eight red apples plus 1 are nine apples, eight apples plus 1 are nine, eight apples plus 1 are less than nine, and nine apples plus 1 are more than eight).
Third, children operate to further consolidate the formation of 9.
1, look at the numbers and get the corresponding number of snowflakes.
2. Look at the number of snowflakes corresponding to the changing digital cards, so as to further perceive the quantitative relationship between 8 and 9.
Fourth, finish this activity after packing up your appliances.
The Formation of Mathematics 9 Middle School Teaching Plans Part II Mathematical Activities;
9. Formation of10
Activity objectives:
1, guide children to perceive that 1 plus 8 is 9, 1 plus 9 is 10, and understand the formation of 9 and 10.
2. Cultivate children's habit of listening carefully and observing carefully.
3. Guide children to be interested in numbers.
4. Cultivate children's good operating habits of cooperative and orderly operation.
Activity preparation:
1, PPT, number1-10;
2. Each group has a flower and a crayon, and each person has an operation sheet.
Activity flow:
First, briefly review the formation of 2-8.
1. Play a clap game to see who speaks quickly and accurately.
Teacher: Let me ask you something, son. How much is 1 added to 1?
Child: Teacher Yao, tell you, 1 plus 1 is 2.
2. Clap your hands and show the numbers 1-8 in turn, and read aloud collectively.
Second, guide children to learn 9. The formation of 10
1, show PPT:
Please take a closer look. What's in the picture? (Birds, flowers, apples)
Would you please count their numbers? (8 birds, 9 flowers, 9 apples)
2. When operating PPT, the number changes (a bird flies in, a flower blooms and an apple is taken away):
Take a closer look. What has changed?
Introduction: 8 birds plus 1 is 9 birds; 8 flowers plus 1 flower is 9 flowers; Nine apples plus one equals eight apples.
3. q:
What is 9 minus 1? (Show "8" to consolidate approval)
What is 8 plus 1? How about 1 plus 9? (Display 9 in turn, 10 to guide children to read)
Third, further perceive the formation of 9, 10.
1, according to the teacher's instructions, children take the corresponding number of flowers:
Please take out the number 8 flower. Friends-children take 8 flowers and line them up.
Think about how to turn eight flowers into nine. -Encourage children to tell stories while operating: 8 dollars plus 1 is 9 dollars.
How did 9 yuan become 10 yuan? If one piece is removed, how many pieces is 10? What is 10 minus 1?
2, introduce the operation list, children operate independently:
Look at the numbers on each house. Count the number of objects in the corresponding house again. Is it the same? If not, please try to be the same.
Fourth, the end.
1, briefly introduce the operation results and encourage short language.
2. Besides nine building blocks, what can the number 9 stand for? 10?
3. Then say the numbers: The teacher casually said the numbers, and the children went on to say.
Teaching reflection:
Mathematics activity is a very enjoyable course for children, because there are more games and more opportunities for children to operate, but it is not so easy for children to really understand the content of this teaching activity and master it skillfully and flexibly.
There is a stone in Liushugou, which was first seen in Jian 'an and formed in Huang Chu. It's written by Taihe, and it's one inch high. "Qin Mu's Picking up Shells in the Ocean of Art": "Under certain pressure, water forms a column of water and rushes out, resulting in a fountain of language. " 。
Formation of activity goal of 9 teaching plans 3 in middle school mathematics;
1, learn the formation of 9 and know that 8 plus 1 is 9.
2. Understand the practical meaning of 9, and know that 9 can represent all objects with a quantity of 9.
Focus of activities:
Learn the composition of 9 and know that 8 plus 1 is 9.
Activity difficulty:
Describe the composition of 9 with complete words.
Activities to be prepared
1, a lamb doll, 9 white rabbits and 9 radishes.
2, the number 9.
Activity process
Clap your hands and review the composition of numbers 2-8.
Second, the lamb's birthday
1. Show the lamb doll: Today is the lamb's birthday, and its good friend Little Rabbit is coming to help.
It celebrates birthdays.
2. Show 8 rabbits: See how many rabbits come. What numbers should be used to represent these eight rabbits?
3. Show 8 carrots: The lamb prepared his favorite carrots to entertain the white rabbit. How many carrots did the lamb prepare? What is the number of eight carrots?
The number 8 can represent 8 rabbits and 8 radishes. What else can it mean?
Third, the formation of learning.
1. Sister Rabbit (leftmost) found out why a sister rabbit was missing. (Like a rabbit, show it to another rabbit) I'm coming. I jump slowly, so don't wait for me.
Children, how many rabbits are coming to the lamb's birthday party now? Why nine rabbits? What's the number of nine rabbits?
3. Is the lamb prepared enough carrots to eat? What shall we do? How many radishes are eight radishes plus one radish? How many numbers should nine radishes represent?
4. Eight rabbits plus one rabbit is nine rabbits, and eight radishes plus one radish is nine radishes. 1 How many times can I add it up?
Fourth, know the number 9.
1. Show the number 9: Let's see what the number 9 looks like. What does the number 9 look like?
2. What else can the number 9 stand for?
3. Abstract: The number 9 can represent all items with a quantity of 9.
