moving target
1, review the composition of numbers within 4, and learn the addition and subtraction of numbers within 4.
2. Know the symbols "+","-"and "=" and understand their meanings.
3. Understand and memorize lyrics and learn to sing with the help of maps, actions and game scenes.
4. Feel the humorous features of songs and listen to music games.
Activities to be prepared
Teaching AIDS for ethnic doll patches, digital cards (1, 2, 3, 4), symbol cards of "+","-"and "=", formula cards (all formulas within 4), and children's picture books.
Activity process
1, review the composition game of numbers within 4: touching the ball or logarithm. For the game "Against 4", the teacher will report "3" and the children will report "1", which is 4 in total. You can take two children to challenge and see who is faster to whom.
2. Learn the addition of numbers within 4. Know "+"and "=".
(1) The teacher orally applied for questioner: A Tibetan child came to the kindergarten, and then two Uighur children came. How many good friends are here now? (and show teaching AIDS)
(2) After the children answer, please tell them how they worked it out. (First 1, then two, then three children. ).
The teacher shows the card; 1, 2, 3, Question: What do these numbers mean? (and paste it in the corresponding place of the patch teaching aid)
(3) Show the "+"and "=" symbol cards and put them in "1. 2。 3 ",the formula is: 1+2 = 3. Teacher: "+"means combination, "=" means a number of * * * *, which means 1+2 = 3. We can use this formula to express what just happened.
(4) Children learn reading formulas.
(5) In Exercise 4, the teacher reported the application problems with other addition formulas, and the children chose the correct formula to express them.
3. Learn the subtraction of numbers within 4.
(1) The teacher orally applied for questioner: There are four children dancing in the garden, and two children have already left. How many children are left? Teacher: There are two left. How did you get this number?
(2) Display "-",know and understand the meaning, and form a subtraction formula.
Teacher: "-"means to remove, which can be used to record what just happened. Example: 4-2 = 2, children read after it.
(4) Other subtraction formulas in Exercise 4.
The teacher reports the application problems orally, and the children choose the correct subtraction formula to express them.
4, children's operation exercises, complete children's books: add the correct symbol composition formula.
Activity reflection:
Children are the masters of mathematics learning, and teachers are the organizers, guides and collaborators of mathematics learning. In the classroom, the child is the protagonist and the teacher is only a supporting role, leaving time and space for children to think, explore and communicate, and paying attention to their emotions, attitudes and thinking in the learning process. Intersperse games or organize some interesting activities in the activities to improve children in a pleasant atmosphere.
