Modeling Integers with Chips

The video tutorial explains how to use integer chips to model the numbers 0, 4, and -5 in two different ways. Integer chips are used to represent positive and negative values, with a positive chip equaling +1 and a negative chip equaling -1. The tutorial demonstrates that zero can be modeled by pairing equal numbers of positive and negative chips. It then shows how to model positive 4 using four positive chips and by adding zero pairs. Similarly, negative 5 is modeled using five negative chips and by adding zero pairs. The tutorial emphasizes the flexibility of using integer chips to represent numbers in multiple ways.

What does a positive chip represent in the integer chip model?

• Zero

• Positive 1

• Positive 2

• Negative 1

How can you represent zero using integer chips?

• By using only negative chips

• By using only positive chips

• By using no chips at all

• By pairing each positive chip with a negative chip

What is one way to model positive 4 using integer chips?

• 2 positive chips and 2 negative chips

• 3 positive chips and 1 negative chip

• 4 negative chips

• 4 positive chips

How can you still model positive 4 after adding a positive and a negative chip?

• It becomes positive 5

• It remains positive 4

• It becomes zero

• It becomes negative 4

What is one way to model negative 5 using integer chips?

• 5 positive chips

• 5 negative chips

• 3 positive chips and 2 negative chips

• 4 negative chips and 1 positive chip

How can you still model negative 5 after adding a positive and a negative chip?

• It becomes zero

• It remains negative 5

• It becomes negative 6

• It becomes positive 5

What happens when you add a positive chip and a negative chip to any model?

• The model remains unchanged

• The model becomes negative

• The model becomes zero

• The model becomes positive

What is the significance of adding models of zero to any integer chip model?

• It halves the model value

• It changes the value of the model

• It keeps the model value the same

• It doubles the model value
