Writing One-Step Equations

The video tutorial introduces students to writing one-step equations using all four operations: addition, subtraction, multiplication, and division. It emphasizes the importance of understanding key vocabulary and provides examples to illustrate how to form equations. Students are encouraged to practice independently using provided examples and a graphic organizer.

What is the main difference between an equation and an expression?

• An equation includes a variable, while an expression does not.

• An equation includes an equal sign, while an expression does not.

• An expression includes a variable, while an equation does not.

• An expression includes an equal sign, while an equation does not.

Which term is used to indicate addition in one-step equations?

• Divided by

• Less than

• More than

• Decreased by

What does the term 'quotient' indicate in one-step equations?

• Division

• Multiplication

• Subtraction

• Addition

Which operation is indicated by the term 'product'?

• Division

• Multiplication

• Subtraction

• Addition

How is '20 more than a number equals 55' written as an equation?

• 20 + N = 55

• N - 20 = 55

• 55 = N + 20

• 20 = N - 55

In the context of one-step equations, what does 'is' signify?

• Subtraction

• An equal sign

• Addition

• Multiplication

What is the correct equation for '9 less than a number is 20'?

• N - 9 = 20

• N + 9 = 20

• 9 - N = 20

• 20 - N = 9

How would you write 'a number minus 10 is 30' as an equation?

• 30 - N = 10

• N + 10 = 30

• 10 - N = 30

• N - 10 = 30

What is the equation for 'a number three times is 27'?

• 3 * N = 27

• N / 3 = 27

• N * 3 = 27

• 27 * N = 3

How is 'the sum of a and 8 is 20' represented as an equation?

• 8 - A = 20

• 20 = A / 8

• A + 8 = 20

• A * 8 = 20
