Subtracting Integers with a Chip Model

The video tutorial explains how to use a chip model to subtract integers, focusing on the concept of zero pairs. It provides examples such as -5 minus 1, 5 minus -2, -1 minus 2, and -1 minus -4, demonstrating how to manipulate the board to achieve the correct result. The tutorial emphasizes understanding zero pairs and maintaining the board's value while subtracting.

What is the first step when using a chip model to subtract integers?

• Add zero pairs to the board.

• Start with the second number on the board.

• Start with the first number on the board.

• Remove all chips from the board.

In the problem negative 5 minus negative 1, what is the result?

• Negative 4

• Negative 6

• Negative 5

• Negative 1

What does a zero pair consist of?

• One positive and one negative chip

• One positive and two negative chips

• Two negative chips

• Two positive chips

When solving 5 minus negative 2, why do we add zero pairs to the board?

• To increase the value of the board

• To remove all positive chips

• To make the board equal zero

• To have enough negatives to take away

What is the result of 5 minus negative 2 using the chip model?

• 5

• 7

• 3

• 2

In the problem negative 1 minus 2, what do you need to add to the board to proceed?

• Zero pairs

• Two negative chips

• One positive and one negative chip

• Two positive chips

What is the result of negative 1 minus 2 using the chip model?

• Negative 1

• Negative 3

• Negative 4

• Negative 2

When solving negative 1 minus negative 4, how many zero pairs do you need to add?

• 1

• 2

• 4

• 3

What is the result of negative 1 minus negative 4 using the chip model?

• Negative 5

• Positive 3

• Negative 3

• Positive 1
