Problem Description:
The image shows examples of decomposing numbers. Decomposing a number means breaking it down into smaller parts that add up to the original number. The task is to understand and explain how these numbers are being decomposed.
Solution Explanation:
#### What is Decomposing Numbers?
Decomposing numbers is a fundamental concept in mathematics where a number is broken down into its component parts. This helps in understanding the structure of numbers and simplifies arithmetic operations like addition, subtraction, multiplication, and division.
#### Examples from the Image:
The image provides several examples of decomposing numbers. Let's analyze each one step by step:
1.
Top Row:
-
10: Decomposed into \(5 + 5\)
- Explanation: The number 10 is split into two equal parts, each being 5.
-
24: Decomposed into \(20 + 4\)
- Explanation: The number 24 is split into a larger part (20) and a smaller part (4).
-
8: Decomposed into \(2 + 6\)
- Explanation: The number 8 is split into two parts, 2 and 6, which add up to 8.
2.
Middle Row:
-
6: Decomposed into \(3 + 3\)
- Explanation: The number 6 is split into two equal parts, each being 3.
-
7: Decomposed into \(5 + 2\)
- Explanation: The number 7 is split into a larger part (5) and a smaller part (2).
-
5: Decomposed into \(4 + 1\)
- Explanation: The number 5 is split into two parts, 4 and 1, which add up to 5.
3.
Bottom Row:
-
11: Decomposed into \(10 + 1\)
- Explanation: The number 11 is split into a larger part (10) and a smaller part (1).
-
4: Decomposed into \(3 + 1\)
- Explanation: The number 4 is split into two parts, 3 and 1, which add up to 4.
-
1: Decomposed into \(1 + 0\)
- Explanation: The number 1 is split into two parts, 1 and 0, where adding 0 does not change the value.
#### General Pattern:
- Each number is broken down into two or more parts that add up to the original number.
- The decomposition can be done in various ways, as shown in the examples. For instance, the number 10 can also be decomposed as \(6 + 4\) or \(7 + 3\), but the image shows one specific decomposition for each number.
#### Why Decompose Numbers?
Decomposing numbers helps in:
1.
Understanding Place Value: Breaking numbers into tens and ones (e.g., 24 = 20 + 4).
2.
Simplifying Calculations: Making addition and subtraction easier by breaking numbers into manageable parts.
3.
Developing Number Sense: Helping students see the relationships between numbers and their components.
Final Answer:
The image demonstrates various ways to decompose numbers into smaller parts that add up to the original number. This technique is useful for building foundational math skills and simplifying arithmetic operations.
\boxed{\text{Decomposing numbers involves breaking them into smaller parts that add up to the original number, as shown in the examples provided.}}
