Visualizing 1 Step Equations in 5th Grade Math

The video tutorial introduces the concept of using visual models to solve one-step equations. It begins by explaining key vocabulary such as variables, equations, and open sentences. The tutorial then demonstrates how to use balance models to visually represent equations, using stars and squares to symbolize variables and numbers. The instructor guides viewers through building visual models for specific equations and encourages them to create their own equations from given visual models, focusing on addition and subtraction.

What is a variable?

• A type of equation

• A number that is always known

• A letter or symbol representing an unknown number

• A mathematical operation

Which of the following is an example of an equation?

• 7 + 2

• x + 4

• 7 + 2 = 10 - 1

• b + 2

What does an open sentence contain?

• Only numbers

• Only letters

• Only symbols

• Variables and can be true or false

What does it mean when a balance is not level?

• The equation is true

• The balance is broken

• Both sides are equal

• One side is heavier

In a balance model, what does a blue square represent?

• An unknown number

• The number two

• The number one

• A variable

How many blue squares are used to represent the number 4 in the equation x + 4 = 10?

• 2

• 1

• 3

• 4

What is the total number of blue squares on the right side of the equation x + 4 = 10?

• 6

• 4

• 8

In the equation x - 6 = 3, how many blue squares are on the left side?

• 3

• 6

• 5

• 4

How many blue squares are on the right side of the equation x - 6 = 3?

• 1

• 2

If a red square equals one and a heart represents a variable, what is the equation for a model with 2 red squares and 7 red squares?

• 2 + x = 7

• 2 - x = 7

• x + 7 = 2

• x - 2 = 7
