Regrouping in Addition Concepts

This video tutorial teaches how to add three-digit numbers with regrouping. It begins with an introduction to the concept, followed by detailed examples of adding 235 + 475, 520 + 190, and 789 + 185. Each example is broken down step-by-step, demonstrating the regrouping process using place value charts and base 10 blocks. The video concludes with a practice problem for viewers to solve independently, reinforcing the skills learned.

What is the first step in adding three-digit numbers with regrouping?

• Begin with the ones place

• Add the tens place first

• Directly add all digits without regrouping

• Start with the hundreds place

In the example of adding 235 and 475, what happens when the sum of the ones place exceeds 9?

• The sum is written as it is

• The sum is ignored

• Regrouping is done by moving to the tens place

• The sum is divided by 2

When adding 235 and 475, what is the result after regrouping the tens place?

• The tens place is subtracted from the hundreds place

• The tens place is added to the ones place

• The tens place is ignored

• 10 tens are moved to the hundreds place

What is the final sum of 235 and 475 after regrouping?

• 800

• 600

• 710

• 900

In the example of adding 520 and 190, what is the sum of the tens place before regrouping?

• 11

• 9

• 12

• 10

What is the result of regrouping the tens place in the addition of 520 and 190?

• The tens place is ignored

• The tens place is added to the ones place

• 10 tens are moved to the hundreds place

• The tens place is subtracted from the hundreds place

What is the final sum of 520 and 190 after regrouping?

• 600
