Subtraction with Regrouping: 2-Digit Challenges

The video tutorial teaches subtraction with regrouping, starting with an introduction to the concept. It provides three examples: subtracting 29 from 53, 38 from 76, and 48 from 74, each demonstrating the use of place value blocks and regrouping. The tutorial concludes by encouraging students to practice the technique.

What is the first step in subtraction with regrouping?

• Start with the tens column

• Immediately regroup

• Draw place value blocks

• Subtract the ones column without regrouping

What do you do if you don't have enough ones to subtract?

• Stop the problem

• Regroup from the tens column

• Guess the answer

• Skip the subtraction

After regrouping, how many ones do you have if you start with 3 and add a ten?

• 13

• 10

• 4

• 3

What is the result of 53 - 29?

• 24

• 33

• 23

• 34

In the second example, what is the first step after drawing place value blocks?

• Subtract the ones column

• Identify the larger number

• Regroup immediately

• Subtract the tens column

How many ones are left after subtracting 8 from 16?

• 8

• 6

• 4

• 10

What is the final answer for 76 - 38?

• 38

• 48

• 28

• 58

Before regrouping in the third example, how many ones are needed to subtract?

• 6

• 8

• 4

• 10

What is the final answer for 74 - 48?

• 24

• 28

• 36

• 26

What is the key concept in subtraction with regrouping?

• Always start with the tens column

• Guessing the answer if unsure

• Regrouping when you don't have enough ones

• Skipping difficult problems
