Adding Integers with Counters

This video tutorial demonstrates how to add integers using two-color counters. Positive integers are represented by yellow counters, while negative integers are represented by red counters. The tutorial covers the process of adding integers by combining counters and identifying zero pairs. Three examples are provided: adding negative integers, adding mixed positive and negative integers, and a final example of adding positive and negative integers. The video emphasizes the importance of understanding zero pairs and provides tips for organizing counters to simplify the process.

What color represents a positive integer in the video?

• Red

• Yellow

• Blue

• Green

Why is it important to write down the key for color representation?

• To ensure everyone understands the representation

• To make the video longer

• To make the counters look colorful

• To confuse the viewers

What is the purpose of using two-color counters in this video?

• To confuse the viewer

• To visually represent positive and negative integers

• To make math more colorful

• To make the video longer

What should you do if you forget what each color represents?

• Guess the colors

• Rewatch the video

• Check the written key

• Ignore the colors

What is the first step in adding integers using counters?

• Multiply the numbers

• Subtract the numbers

• Represent each number with counters

• Divide the numbers

What are zero pairs in the context of adding integers?

• Pairs that multiply to zero

• Pairs that subtract to zero

• Pairs that divide to zero

• Pairs that add up to zero

What is the result of combining a positive and a negative counter?

• A larger number

• Zero

• A negative number

• A positive number

In the example of adding -3 and -2, what is the result?

• 5

• -5

• -1

• 0

When adding -3 and -2, why are brackets around the answer optional?

• They are always necessary

• They make the answer look clearer

• They are used to confuse the viewer

• They are required by math rules

What is the result of adding +2 and -4 using counters?

• 2

• 4

• 0

• -2
