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

• 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
