Exploring Tape Diagrams for Equation Representation

Miss Toledo introduces tape diagrams to represent equations. She demonstrates solving equations like 3x + 18 = 114 and 3(y + 18) = 114 using tape diagrams. The video also covers writing equations from given tape diagrams, emphasizing understanding the relationship between parts and totals in equations.

What is the purpose of using tape diagrams in equations?

• To make equations more complex

• To avoid using algebra

• To solve equations faster

• To visualize the components of an equation

In the equation 114 = 3x + 18, what does the total 114 represent in the tape diagram?

• The sum of 3x and 18

• The value of x

• The difference between 3x and 18

• The number of boxes

How do you find the value of x in the equation 114 = 3x + 18 using a tape diagram?

• Multiply 114 by 3 and then subtract 18

• Add 18 to 114 and then divide by 3

• Subtract 18 from 114 and then divide by 3

• Divide 114 by 3 and then add 18

In the equation 114 = 3(Y + 18), how is the tape diagram divided?

• Into three groups of 18

• Into three groups of Y + 18

• Into three groups of 114

• Into three groups of Y

What is the first step to solve 114 = 3(Y + 18) using a tape diagram?

• Multiply 114 by 3

• Subtract 18 from 114

• Add 18 to 114

• Divide 114 by 3

What does each group represent in the tape diagram for 114 = 3(Y + 18)?

• Y

• 38

• 114

• 18

How can you find the value of Y in the equation 114 = 3(Y + 18) using subtraction?

• Multiply 18 by 38

• Subtract 18 from 38

• Add 18 to 38

• Divide 18 by 38

What is another method to solve 114 = 3(Y + 18) using tape diagrams?

• Subtract 54 from 114 and then divide by 3

• Add 54 to 114 and then divide by 3

• Multiply 54 by 114 and then subtract 3

• Divide 54 by 114 and then add 3

In the tape diagram representing 46 = 26 + 4x, what does the number 26 represent?

• The difference between 46 and 4x

• The value of x

• A part of the total 46

• The number of boxes

How can you write an equation from a tape diagram where the total is 46, part is 26, and there are 4x?

• 46 = 4x + 26

• 46 = 26 - 4x

• 46 = 4x - 26

• 46 = 26 + 4x
