To solve the problem of Big Big Wolf and Big Big Wolf buying breakfast, how much does it cost for students to buy their own breakfast? In the process of these problems. Through group cooperation and independent calculation, the simple calculation method of decimal addition and subtraction is mastered, and the close connection between mathematics and students' daily life is felt in the calculation process, which enhances the interest in learning mathematics and completes the teaching goal.
Master the principle of decimal point alignment in learning, understand the calculation method of decimal addition and subtraction, and break through the difficulties.
Third, the whole class highlights students' dominant position and teachers' guiding role.
From asking students to calculate how much it costs to buy breakfast with gray and wolf, and calculate it in a way that students like, to asking students to choose any two foods as a match. Step by step to highlight students' dominant position. Why is the number and decimal point aligned the same when the teacher calculates vertically? Guide students to understand the principle step by step. It conforms to the law of education and teaching with students as the main body and teachers as the leading factor.
In a word, Mr. Zhao Can deeply understands the teaching materials, studies the curriculum standards and grasps the characteristics of the students in this class.
