Subtracting Double Digit Numbers Using Expanded Form

The video tutorial teaches how to subtract double-digit numbers using expanded form. The example used is 63 minus 48, demonstrated with blocks. The process involves expanding the numbers, rearranging them, and using a strategy to handle subtraction when direct subtraction isn't possible. The tutorial emphasizes the importance of understanding number parts and using blocks to visualize the subtraction process.

What is the main objective of the lesson discussed in the video?

• Dividing double-digit numbers using expanded form

• Adding double-digit numbers using expanded form

• Subtracting double-digit numbers using expanded form

• Multiplying double-digit numbers using expanded form

How is the number 63 represented in expanded form?

• 40 plus 23

• 50 plus 13

• 60 plus 3

• 70 minus 7

Why do we need to regroup when subtracting 48 from 63?

• Because 63 is an odd number

• Because 48 is an even number

• Because 63 is greater than 48

• Because 3 is less than 8

What do we do with the '10' when regrouping?

• Add it to the tens place

• Convert it into 10 ones

• Subtract it from the total

• Ignore it

What is the expanded form of 48?

• 30 plus 18

• 50 minus 2

• 40 plus 8

• 60 minus 12

What is the result of subtracting 50 minus 40?

• 15

• 10

• 5

• 20

After regrouping, what is the new value of the ones place in 63?

• 13

• 12

• 11

• 10

What is the result of subtracting 13 minus 8?

• 6

• 5

• 4

• 3

What is the final result of 63 minus 48?

• 10

• 12

• 15

• 18

Why do we add 10 and 5 at the end of the subtraction process?

• To get the final answer

• To verify the expanded form

• To ensure the numbers are correct

• To check the subtraction
