Teaching plan of monkey treating guests in large class mathematics activities 1 activity goal
1. Find different combinations of objects in operation and develop children's preliminary reasoning ability.
2. Perceive the fun of mathematical activities.
Activities to be prepared
1, an animal headdress, a monkey and a squirrel.
2, each group has a small basket, each person 10 paper candy.
3.5 cupcakes, 4 empty cans and 3 biscuit bags.
Activity process
First, show the picture monkey.
4. Let children understand simple mathematical principles.
5. Develop children's logical thinking ability.
1. Teacher: The little monkey's brother wants to invite his good friend to celebrate his birthday and has prepared a lot of sweets.
In order to let every friend eat it, it prepares one or two sweets for each guest.
My friend is here. Little monkey is so happy! However, it was not until his friend left that he found out how many small guests came today. When it tidied up the room, it found that the little guests left 10 pieces of candy paper in the wastebasket.
2. Question: How many sweets did the guests eat?
3. Help the little monkey's brother calculate how many small animals may come today? Would you please think about it?
How many guests will come if each guest only eats one candy?
5. How many guests will come if each guest eats two pieces of candy?
6. If each guest can eat one candy or two candy, how many guests will come?
7. Children's operation.
Let the children each take 10 piece of paper candy. How many guests are there?
8. Compare the three ways, how many people come at most and how many people come at least?
Second, show the picture 1 again. Now hedgehog is going to treat. It prepared two or three kinds of food for each guest until all the guests left, and the little squirrel didn't know how many guests came. When cleaning the house, it found five cake paper cups, four empty cans and three biscuit bags in the waste box.
Now, please guess how many guests there are?
3. How much food did the guests eat? Shall we count them together?
How many guests will come if each guest only eats two kinds of food? The teacher operates.
5. If each guest eats three kinds of food, how many guests are there? Let's figure it out. Please let the children operate it.
6. Now, ask the children to think about whether there are other ways. If each guest eats two kinds of food and some people eat three kinds of food, how many guests are there? Now, please use your head and do the math. Ask the child to come forward to operate.
7. Let the children compare, and at most only a few people will come. How many people will come at least?
Third, the teacher concluded that today we helped the little monkey and the little hedgehog solve the problem. They all praised the children for their cleverness. Please help them next time they are in trouble. If children encounter such difficulties, we can also use this method to calculate.
Teaching reflection:
Judging from the whole activity, I think the whole activity is compact, the children have learned their goals in the activity, and their interest in participating in the classroom is not very high. This may be because my design is not suitable for their age characteristics, and the activity design is a little high. In the future activities, I will make more improvements to make my activities suitable for the age characteristics of the children in the class and let them learn knowledge in relaxed and happy activities. I will also exercise my language expression ability more, and I will make myself speak Mandarin better in my future work.
Big class math activities, small monkeys treat guests, teaching plan 2, activity objectives:
1. Find different combinations of objects in operation and develop children's preliminary reasoning ability.
2. Perceive the fun of mathematical activities.
3. Let children understand simple mathematical principles.
4. Cultivate children's habit of speaking while operating.
Key points and difficulties:
Discover different combination methods.
Make simple reasoning according to the prompt.
Activity preparation:
1, an animal headdress, a monkey and a squirrel.
2, each group has a small basket, each person 10 paper candy.
3.3 jelly shells, 4 candy wrappers and 5 biscuit bags.
Activity flow:
1, Xiutu Monkey.
(1) Teacher: The little monkey's brother wants to invite his good friends as his guests for his birthday, and he has prepared a lot of sweets. In order to let every friend eat it, it prepares one or two sweets for each guest. My friend is here. Little monkey is so happy! However, it was not until his friend left that he found out how many small guests came today. When it tidied up the room, it found that the little guests left 10 pieces of candy paper in the wastebasket.
(2) The teacher asked: How many sweets did the guest eat?
(3) Help Monkey Count how many small animals may come today? Would you please think about it?
(4) If each guest only eats one candy, how many guests are there?
(5) If each guest eats two pieces of candy, how many guests are there?
(6) If each guest can eat one candy or two candy, how many guests will come?
(7) children's operation. Let the children each take 10 piece of paper candy. How many guests are there?
(8) Comparing the three methods, how many people come at most and how many people come at least?
2. Play the picture again, squirrel.
(1) Now the little squirrel is going to treat. It prepared two or three kinds of food for each guest until all the guests left, and the little squirrel didn't know how many guests came. When cleaning the house, it found three jelly shells, four candy wrappers and five biscuit bags in the waste box.
(2) Now, please guess how many guests showed up?
(3) How much food did the guests eat? Shall we count them together?
(4) If each guest only eats two kinds of food, how many guests are there? The teacher operates.
(5) If each guest eats three kinds of food, how many guests are there? Let's figure it out. Please let the children operate it.
(6) Now, ask the children to think about whether there is another way. If each guest eats two foods and three foods, how many guests are there? Now, please use your head and do the math. Ask the child to come forward to operate.
(7) let the children compare, and at most a few people will come. How many people will come at least?
3. Teacher's summary:
Today, we helped the little monkey and the little squirrel solve this problem. They all praised the children for their cleverness. Please help them next time they are in trouble. If children encounter such difficulties, we can also use this method to calculate.
