Mastering Subtraction with Place Value Disks

What is the initial subtraction problem discussed in the video?

• 264 minus 147

• 264 minus 174

• 274 minus 146

• 247 minus 164

What is the purpose of using place value disks in subtraction?

• To complicate the subtraction process

• To avoid using traditional algorithms

• To make the calculation faster

• To visually represent and manipulate the numbers

How many hundreds disks are used to represent the number 264?

• Two

• Three

• One

• Four

What is the first step when you don't have enough ones to subtract?

• Borrow from the hundreds column

• Add more tens disks

• Regroup a tens disk into ten ones

• Ignore the ones place

After regrouping, how many ones are available for subtraction?

• Ten

• Fourteen

• Seventeen

• Seven

What is the result of subtracting 7 from 14 in the ones column?

• Nine

• Seven

• Eight

• Six

How many tens are left after regrouping and subtraction?

• One

• Three

• Five

• Two

What does regrouping involve in the context of place value disks?

• Converting a higher place value disk into multiple lower place value disks

• Adding more disks to the same column

• Removing all disks and starting over

• Switching disks between columns without conversion

What is the final result of the subtraction problem?

• 117

• 127

• 107

• 137

How does the video suggest reinforcing the subtraction process?

• By memorizing the steps

• By using a calculator

• By guessing and checking

• By paralleling the process with a traditional algorithm
