1, combined with the specific situation of "bear treat", try to compile the multiplication formula of 4 through group cooperation and exploration.
2. Students can master the multiplication formula of 4 through back-to-back, back-to-back for boys and girls, back-to-back for deskmates and back-to-back for teachers. They can use formulas to multiply and solve mathematical problems in life.
3. Encourage students to actively discover the mathematical problems in life and experience the close relationship between mathematics and life.
4. Cultivate students' mathematics consciousness and stimulate students' interest in learning mathematics.
Teaching emphasis: Formulating and mastering formulas.
Teaching difficulties: the flexible use of formula calculation to solve practical problems in life.
Teaching preparation: multimedia courseware
Teaching process:
First, create a situation to stimulate interest
1, paving before class
Play the song "candied haws" by multimedia.
2. Expose the theme in the settings.
The teacher shouted, "Sugar-coated haws, sugar-coated haws, did the children eat sugar-coated haws?"
(Students are free to answer)
Teacher: From your answers, we can see that all the students want to eat candied haws, right?
When Bear heard about it, he wanted to treat everyone to candied haws, but it had to be his treat. He wants to answer questions loudly, actively and in a standard sitting position ... Do you want to be his guest? (Student) Today we are going to learn "Bear Treat" and look forward to the wonderful performance of the students. (Teacher's blackboard writing topic)
Second, the formulation of cooperative exploration formula
1, observing the picture causes problems.
Bear can make his own candied haws. Look! He is busy nervously. (Multimedia demonstration of theme map)
2. Students observe and report the mathematical information they find and ask questions.
3, team cooperation to complete the form
Encourage students to solve problems in various ways.
