Explain how the commutative property of addition applies to the equation $3 + 5$ and $5 + 3$. What does this property imply about the sum?
Explain how the commutative property of addition applies to the equation $3 + 5$ and $5 + 3$. What does this property imply about the sum?
The commutative property states that the order in which two numbers are added does not change their sum, so $3 + 5$ equals $5 + 3$, both resulting in $8$.
Define the identity property of addition and give an example using a single digit number.
Define the identity property of addition and give an example using a single digit number.
The identity property of addition states that adding zero to any number does not change the number. For example, $4 + 0 = 4$.
If you know that $6 + 6$ equals $12$, what is the relationship of this equation to the concept of doubles? Provide a brief explanation.
If you know that $6 + 6$ equals $12$, what is the relationship of this equation to the concept of doubles? Provide a brief explanation.
The equation $6 + 6$ is an example of doubles, where a number is added to itself, resulting in a sum that is twice the original number, which is $12$.
In a word problem, if Leah bought 4 apples and her friend gave her 1 more apple, how can this situation illustrate the concept of making ten with the addends?

Study Notes
Math Test Components
- Single Digit Addition: Focus on adding numbers from 0 to 9.
- Make a 10: Practice combinations that total 10, such as 7 + 3, 6 + 4, and 5 + 5.
- Doubles: Recognize and solve equations involving two identical addends, like 2 + 2, 3 + 3, up to 9 + 9.
- Near Doubles: Learn to use doubles to find sums, for instance, 2 + 3 (which is near to 2 + 2).
- Equations: Formulate simple equations involving addition to enhance problem-solving skills.
Word Problems
- Develop word problems that require students to apply addition in real-life scenarios, such as:
- "If you have 3 apples, and your friend gives you 4 more, how many apples do you have?"
- "There are 2 cars in the driveway and 5 more arrive. How many cars are there now?"
Vocabulary Terms
- Commutative Property: The order of addends does not change the sum (e.g., 2 + 3 = 3 + 2).
- Identity Property: The sum of any number and zero is the number itself (e.g., 5 + 0 = 5).
- Addend: A number that is added to another number.
- Sum: The result of adding two or more addends together.
- Doubles: Refers to adding two identical numbers.
- Near Doubles: Uses the doubles strategy to make a mental calculation easier (e.g., using 4 + 4 to help with 4 + 5).
- Add: The basic operation of combining two or more numbers.
