Modeling Integer Addition with Chips

The video tutorial explains how to add integers using colored chips as models. Yellow chips represent positive integers, while red chips represent negative integers. The tutorial covers modeling positive and negative numbers, creating zero pairs, and provides examples of adding both positive and negative integers. It concludes with instructions for completing related tasks.

What color counter chip is used to represent a positive integer?

• Green

• Red

• Blue

• Yellow

How would you model the number negative three using counter chips?

• Three yellow chips

• No chips

• Three red chips

• Two yellow chips and one red chip

What happens when a yellow and a red counter chip are paired together?

• They cancel each other out

• They double the value

• They become a negative pair

• They become a positive pair

In the example of adding positive two and positive four, how many yellow chips are used in total?

• Four

• Five

• Six

• Seven

When modeling negative five plus negative two, what is the total number of red chips used?

• Eight

• Six

• Seven

• Five

In the example of negative one plus three, how many zero pairs are formed?

• Three

• None

• Two

• One

What is the result of adding positive four and negative five using counter chips?

• Positive five

• Zero

• Negative one

• Positive one

Why might parentheses be used around negative numbers in some worksheets?

• To show addition

• To indicate multiplication

• To separate from positive numbers

• To highlight the negative sign

What is the significance of zero pairs in integer addition?

• They increase the total value

• They decrease the total value

• They cancel out to zero

• They have no effect

How can you determine the sign of the result in an addition problem without performing the addition?

• By using a calculator

• By looking at the first number

• By comparing the number of yellow and red chips

• By counting the total chips
