Additions

What is the definition of addition?

• Addition is a mathematical operation that represents the total amount of objects together in a collection.

• Addition is the process of dividing a number into equal parts.

• Addition is a method of finding the difference between two numbers.

• Addition is the operation of multiplying two numbers together.

What is the commutative property of addition?

• The commutative property of addition states that changing the order of the addends does not change the sum.

• The commutative property of addition states that the sum of two numbers is always greater than either number.

• The commutative property of addition states that the sum of two numbers is always equal to their product.

• The commutative property of addition states that addition can only be performed on whole numbers.

Calculate the sum of 5 and 8.

• 12

• 13

• 14

What is a double number line?

• A visual representation that shows two sets of numbers, often used to illustrate relationships between quantities and to help with addition and subtraction.

• A type of graph that only displays one set of numbers.

• A method for solving equations without visual aids.

• A line that represents only negative numbers.

How can you use objects to demonstrate addition?

• By using physical objects like blocks or counters to group them together and count the total number of objects.

• By writing numbers on paper and adding them without any physical representation.

• By using a calculator to input numbers and get the sum directly.

• By drawing pictures of objects and counting them visually.

What is the sum of 5 and 10?

• 12

• 13

• 15

• 17

What strategies can be used to solve addition problems?

• Counting on, using number lines, and breaking numbers apart (decomposing)

• Multiplying numbers together, using fractions, and rounding numbers

• Subtracting numbers, using decimals, and estimating answers

• Dividing numbers, using percentages, and applying algebraic formulas

What is the associative property of addition?

• The associative property of addition states that the way in which numbers are grouped when adding does not change the sum.

• The associative property of addition states that the order of numbers does not affect the sum.

• The associative property of addition states that adding zero to a number does not change the number.

• The associative property of addition states that the sum of two numbers is always greater than either number.

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 along its length. It is used in addition to visually represent the process of adding numbers by moving to the right on the line.

• A number line is a circular diagram used to represent numbers in a non-linear fashion.

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

• A number line is a tool used for subtraction by moving to the left on the line.
