Addition with Regrouping for 3rd Graders

The video tutorial explains how to solve addition problems with regrouping using base ten shorthand and direct column addition. It provides examples, such as adding 247 and 139, and demonstrates trading bits for skinnies and skinnies for flats to follow the fewest pieces rule. An alternative method using direct column addition is also presented, emphasizing understanding of the base ten system.

What is the first step in solving an addition problem with regrouping?

• Multiply the numbers

• Subtract the smaller number from the larger number

• Place the numbers in the proper columns

• Combine all the numbers together
