Multi-Digit Addition with Regrouping

The video tutorial focuses on teaching multi-digit addition with regrouping. It begins with an introduction to the concept and demonstrates solving two problems. In the first problem, the teacher explains regrouping from ones to tens, hundreds, and thousands columns, resulting in the final answer of 61,270. The second problem involves similar steps, with regrouping across columns, leading to the answer of 55,016. The tutorial emphasizes understanding the regrouping process in multi-digit addition.

What is the first step in multi-digit addition with regrouping?

• Add the thousands column first

• Add the hundreds column first

• Add the ones column first

• Add the tens column first

When adding 9 ones and 1 one, what do you do with the result?

• Put 10 in the ones column

• Put 0 in the ones column and regroup 1 to the tens column

• Put 1 in the ones column and regroup 0 to the tens column

• Put 9 in the ones column and regroup 1 to the tens column

How many groups of ten do you get when you add 3 tens, 3 tens, and 1 ten?

• 8 groups of ten

• 9 groups of ten

• 7 groups of ten

• 6 groups of ten

What is the result of adding 6 hundreds and 6 hundreds?

• 11 hundreds

• 12 hundreds

• 13 hundreds

• 10 hundreds

When you have 12 hundreds, what do you do with the extra hundreds?

• Move all 12 to the thousands column

• Move 10 to the hundreds column and regroup 2 to the thousands column

• Move 2 to the hundreds column and regroup 10 to the thousands column

• Keep all 12 in the hundreds column

In problem number two, what is the result of adding 9 and 7 in the ones column?

• 15

• 14

• 16

• 17

What do you do with the group of ten when you get 16 in the ones column?

• Put 6 in the ones column and regroup 0 to the tens column

• Put 0 in the ones column and regroup 1 to the tens column

• Put 1 in the ones column and regroup 6 to the tens column

• Put 6 in the ones column and regroup 1 to the tens column

What is the result of adding 7 tens, 3 tens, and 1 ten?

• 10 tens

• 11 tens

• 12 tens

• 13 tens

When you have 10 hundreds, what do you do with them?

• Move all 10 to the thousands column

• Move 10 to the hundreds column and regroup 0 to the thousands column

• Move 0 to the hundreds column and regroup 10 to the thousands column

• Keep all 10 in the hundreds column

What is the final answer for problem number two?

• 55,100

• 55,016

• 55,010

• 55,000
