1. Basic division problem:
6 ÷ 2 = ?
8 ÷ 4 = ?
10 ÷ 5 = ?
12 ÷ 3 = ?
9 ÷ 3 = ?
2. Division of zero:
0 ÷ 2 = ?
0 ÷ 5 = ?
0 ÷ 10 = ?
0 ÷ 3 = ?
0 ÷ 8 = ?
3. The relationship between division and multiplication:
If there are four apples, give them to two children. How many apples can each person take?
If you have 9 cars, put them in 3 boxes. How many cars are there in each box?
If you have 15 pencils and put them in 5 boxes, how many pencils are there in each box?
4. Compound division:
There are 18 sweets. Give them to three children. How many sweets can everyone get? And give it to two children. How many sweets can each person get?
There are 24 story books in 4 boxes. How many story books are there in each box? Then put it in three big boxes. How many story books are there in each big box?
5. Analyze and solve problems:
Xiaoming has 20 chocolates. If he eats four chocolates a day, how many days can he eat?
A * * * has 30 pencils. If everyone needs five pencils, how many people can you give?
If there are 36 oranges, give them to 6 friends on average. How many oranges can each friend get?
Teaching methods and guidance:
Understand the concept of division: emphasize that division is the process of distributing goods or numbers, and help students understand the concept of "average distribution"
Explore the relationship between division and other operations: through the relationship with addition and multiplication, let students understand the practical significance of division and promote the overall understanding of mathematical operations.
Using teaching AIDS and images: Use teaching AIDS, pictures or objects to demonstrate and operate, so that students can understand the concept of division more intuitively.
Guided by stories and problem solving: provide real-life problems, guide students to analyze, reason and solve problems, and cultivate students' logical thinking ability.
The above topics are designed to help students consolidate the basic concepts of division, guide students to think and solve practical problems, and improve their mathematical thinking and operation ability. In teaching, we should not only pay attention to the training of verbal arithmetic, but also pay attention to the cultivation of students' ability to understand and solve problems.
