Understand the concept of multiples: First, understand what multiples are. Multiplication is the division of one number by another, and the quotient obtained is called multiple. For example, the quotient of 10 divided by 2 is 5, so 5 is five times that of 2.
Identify the information in the problem: when solving multiple problems, it is necessary to clarify the information given in the problem and the goal to be solved. For example, a question may ask how many times a certain number is, or which number is several times that of another number.
Calculate multiples by multiplication: if you know the b degree of a number, you can find the number A itself, which can be solved by division or equation. If you know that several times of one number is equal to another number, you can calculate the value of this number by multiplication.
Drawing helps to understand: for more complex problems, figures and relationships can be represented by graphics. For example, the relationship between quantity and multiple can be represented by rectangle or line segment.
Check the answer: after getting the answer, check whether the answer meets the requirements of the topic and the actual situation. For example, the question is which number is several times the other number, and the answer should be an integer, otherwise it is wrong.
Here is a concrete example:
Title: A number is 8 times 6. What is the number?
Step 1: Identify the information in the question. The title tells us that there is a number, which is 8 times of 6.
Step 2: Calculate multiples by multiplication. According to the definition of multiple, if a number is 8 times 6, then this number is 6 times 8.
Step 3: Calculate. 6 times 8 equals 48.
Step 4: Check the answers. 48 is an integer, which meets the requirements of the topic.
In short, to solve the math multiple problem in grade three, we need to understand the concept of multiple, identify the information in the problem, calculate multiple by multiplication, draw pictures to help us understand, and finally check whether the answer meets the requirements. Through these steps, students can effectively solve multiple problems and improve their math scores.
