Essential Question

How can you use place value to subtract 3-digit numbers?

Unlock Unlock the the Problem Problem Ava sold 473 tickets for the school play. Kim sold 294 tickets. How many more tickets did Ava sell than Kim?

• Do you need to combine or compare the number of tickets sold?

• Circle the numbers you will need to use.

Use place value to subtract. Subtract. 473 – 294 Estimate. 475 – 300 =

__

STEP 1

STEP 3

Subtract the ones. 3 < 4, so regroup.

Subtract the tens. 6 < 9, so regroup.

Subtract the hundreds. Add to check your answer.
