Integer Subtraction Concepts and Strategies

This video tutorial covers integer subtraction using counters. It explains how to represent positive and negative integers with different colored counters and demonstrates subtraction by removing counters. The tutorial also introduces the concept of zero pairs, which are used when there aren't enough counters to subtract. Various examples illustrate subtraction with both like and unlike signs, and the video concludes with a brief overview of the next lesson on subtracting integers using a number line.

What do the different colors of counters represent in integer subtraction?

• Fractions and decimals

• Addition and subtraction

• Positive and negative integers

• Multiplication and division

In a simple subtraction problem, if you have three positive counters and need to subtract two, what is the result?

• Two negative counters

• One positive counter

• Three negative counters

• Zero counters

When subtracting integers, why might you need to add zero pairs?

• To make the problem more complex

• To have enough counters to subtract

• To balance the equation

• To increase the number of counters

What is the term for the first number in a subtraction problem?

• Dividend

• Minuend

• Difference

• Subtrahend

If the absolute value of the minuend is less than the subtrahend, what must you do?

• Subtract zero pairs

• Add zero pairs

• Multiply the counters

• Divide the counters

How many zero pairs are needed if you have a negative three and need to subtract a positive eight?

• Five zero pairs

• Eight zero pairs

• Three zero pairs

• Ten zero pairs

What is the result of subtracting a negative six from a negative two?

• Negative four

• Positive four

• Positive eight

• Negative eight

In the context of integer subtraction, what does a zero pair consist of?

• Two positive counters

• Two negative counters

• One positive and one negative counter

• One positive and two negative counters

What is the result of subtracting a positive seven from a positive four?

• Negative three

• Positive three

• Negative seven

• Zero

If you have a negative one and need to subtract a negative eight, what is the result?

• Negative seven

• Positive nine

• Positive seven

• Negative nine
