• A technique used for multiplying numbers together.

• A way to divide numbers into smaller parts.

What is the sum of 6 and 8?

• 12

• 14

• 16

• 10

What is the identity property of addition?

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

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

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

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

What is the associative property of addition?

• The associative property of addition states that the way in which numbers are grouped does not change their sum (e.g., (a + b) + c = a + (b + c)).

• The associative property of addition states that the order of numbers does not affect their sum (e.g., a + b = b + a).

• The associative property of addition states that adding zero to a number does not change its value (e.g., a + 0 = a).

• The associative property of addition states that the sum of two negative numbers is always positive.

How do you solve a word problem involving addition?

• Identify the quantities to be added, translate the words into a mathematical equation, and then perform the addition.

• Only focus on the final answer without considering the details of the problem.

• Ignore the context and just add the numbers mentioned in the problem.

• Read the problem multiple times without attempting to solve it.

What is a number line and how is it used in addition?

• A number line is a straight line with numbers placed at equal intervals. It is used in addition to visually represent the process of combining numbers.

• A number line is a circular diagram used to represent fractions and their relationships.

• A number line is a graph that shows the relationship between two variables in an equation.

• A number line is a tool used for measuring angles in geometry.
