Understanding Fact Families in Mathematics

In mathematics, a fact family is a group of related multiplication and division facts that involve the same numbers. These numbers are often referred to as the "factors" or "multiples" of a particular number. Fact families are an essential concept in mathematics, as they help students understand the relationships between numbers and develop their problem-solving skills.

The Importance of Fact Families

Fact families are crucial in mathematics because they help students understand the concept of multiplication and division as inverse operations. This means that when a student multiplies two numbers together, they are essentially finding the product of those numbers. On the other hand, when a student divides one number by another, they are finding the quotient of those numbers.

The Relationship Between Multiplication and Division

The relationship between multiplication and division is a fundamental concept in mathematics. When a student multiplies two numbers together, they are essentially finding the product of those numbers. For example, if a student multiplies 2 and 6 together, they get 12. This means that 2 multiplied by 6 equals 12.

The Concept of Fact Families in the Given Problem

In the given problem, we are presented with three number sentences that form a fact family:

${ 12 + 2 = 14 \}$ ${ 6 \times 2 = 12 \}$ ${ 2 \times 6 = 12 }$

The first number sentence states that 12 plus 2 equals 14. The second and third number sentences state that 6 multiplied by 2 equals 12, and 2 multiplied by 6 equals 12, respectively.

Analyzing the Options

Now, let's analyze the options given to complete the fact family:

A. $${ 12 \times 1 = 12 }$$ B. $${ 12 \div 1 = 12 }$$ C. $${ 12 \div 6 = 2 }$$ D. $${ 12 \div 2 = 6 }$$

Option A: 12 × 1 = 12

Option A states that 12 multiplied by 1 equals 12. This is a true statement, but it does not complete the fact family. The fact family requires a number sentence that involves the numbers 12, 6, and 2.

Option B: 12 ÷ 1 = 12

Option B states that 12 divided by 1 equals 12. This is also a true statement, but it does not complete the fact family. The fact family requires a number sentence that involves the numbers 12, 6, and 2.

Option C: 12 ÷ 6 = 2

Option C states that 12 divided by 6 equals 2. This is a true statement, and it involves the numbers 12, 6, and 2. Therefore, option C completes the fact family.

Option D: 12 ÷ 2 = 6

Option D states that 12 divided by 2 equals 6. This is a true statement, but it does not complete the fact family. The fact family requires a number sentence that involves the numbers 12, 6, and 2.

Conclusion

In conclusion, the correct answer is option C: $${ 12 \div 6 = 2 }$$. This option completes the fact family by involving the numbers 12, 6, and 2. The other options do not complete the fact family, as they either involve different numbers or do not provide a true statement.

Fact Families in Real-Life Applications

Fact families have numerous real-life applications. For example, in shopping, a student may need to calculate the cost of an item by multiplying the price by the quantity. In cooking, a student may need to calculate the amount of ingredients needed by dividing the total amount by the number of servings. In science, a student may need to calculate the area of a rectangle by multiplying the length by the width.

Tips for Understanding Fact Families

To understand fact families, students should:

Practice multiplying and dividing numbers to develop their problem-solving skills.
Use real-life examples to illustrate the concept of fact families.
Create their own fact families to reinforce their understanding of the concept.
Use visual aids, such as diagrams or charts, to help them understand the relationships between numbers.

Conclusion

$In conclusion, fact families are an essential concept in mathematics that helps students understand the relationships between numbers. By understanding fact families, students can develop their problem-solving skills and apply mathematical concepts to real-life situations. The correct answer to the given problem is option C: $${ 12 \div 6 = 2 }$$.<br/> **Fact Families Q&A**$
