What is regrouping in addition?

• A method used to simplify addition by carrying over values to the next column when sums exceed 10.

• A technique for subtracting numbers by borrowing from the next column.

• A strategy for multiplying large numbers by breaking them into smaller parts.

What is the commutative property of addition?

• The order of numbers does not affect the sum (e.g., a + b = b + a).

• The sum of two numbers is always greater than either number.

• The sum of a number and zero is the number itself.

• The sum of two negative numbers is always positive.

What is the identity property of addition?

• Adding one to a number does not change the number (e.g., a + 1 = a).

• Adding zero to a number does not change the number (e.g., a + 0 = a).

• Subtracting zero from a number does not change the number (e.g., a - 0 = a).

• Multiplying a number by one does not change the number (e.g., a * 1 = a).

What is a word problem in addition?

• A type of problem that requires subtraction to solve.

• A mathematical problem presented in a narrative form that requires addition to solve.

• A problem that involves multiplication and division.

• A simple arithmetic problem with no narrative context.

What is a number line?

• A visual representation of numbers in a straight line, used to illustrate addition and other operations.

• A method of organizing numbers in a circular format.

• A tool used for measuring angles in geometry.

• A graphical representation of statistical data.

What is the associative property of addition?

• The way numbers are grouped does not affect the sum (e.g., (a + b) + c = a + (b + c)).

• The order of numbers does not affect the sum (e.g., a + b = b + a).

• The sum of any two numbers is always greater than either number.

• The sum of a number and zero is the number itself (e.g., a + 0 = a).

What is the sum of two numbers?

• The result of adding two numbers together.

• The difference between two numbers.

• The product of two numbers.

• The average of two numbers.
