3-Digit Addition with Regrouping Challenge

Where should you start adding in a three-digit addition problem?

• In the ones place

• Anywhere is fine

• In the tens place

• In the hundreds place

Why is starting in the ones place important?

• No specific reason

• It's a math rule

• To ensure accurate regrouping

• It's easier

What should you do if the sum in the ones place is ten or more?

• Move to the next problem

• Regroup to the next place

• Ignore the extra value

• Start over

What does a sum of thirteen in the ones place result in?

• 3 in the ones place, 1 regrouped

• 13 in the ones place

• 1 in the ones place, 3 regrouped

• Nothing, it's an error

How is regrouping visually represented in the problem?

• With a circle

• It is not visually represented

• With a line

• With a '1' above the next place

In the tens place, what does a sum of ten indicate?

• Ignore and move to hundreds place

• Restart the addition process

• Place a 0 in the tens place and regroup 1

• Place a 1 in the tens place

What does the phrase 'nine or less, let it rest' imply?

• If the sum is 9 or less, no regrouping is needed

• Always start with the nines

• If the sum is 9, start over

• Ignore sums of 9 or less
