Adding and Subtracting Whole Numbers with Regrouping

What is the main objective of today's lesson?

• To solve algebraic equations

• To add and subtract whole numbers with regrouping

• To understand division of whole numbers

• To learn multiplication of whole numbers

When adding 3278 and 854, what is the sum of the ones place?

• 16

• 14

• 12

• 10

In the addition example, what do you do after adding the ones place?

• Move to the hundreds place

• Move to the thousands place

• Carry over to the tens place

• Subtract the tens place

In the subtraction example of 625 minus 472, why do we need to regroup from the hundreds place?

• Because there are not enough ones

• Because there are not enough tens

• Because there are not enough hundreds

• Because there are not enough thousands

What is the result of 625 minus 472?

• 153

• 163

• 173

• 183

In the subtraction example of 2384 minus 468, what is the first step?

• Subtract the hundreds place

• Subtract the tens place

• Regroup from the thousands place

• Subtract the ones place

What is the result of 2384 minus 468?

• 1946

• 1936

• 1926

• 1916

In the final subtraction example, why do we need to regroup from the hundreds place?

• Because there are not enough ones

• Because there are not enough tens

• Because there are not enough hundreds

• Because there are not enough thousands

What is the result of 1405 minus 326?

• 1109

• 1079

• 1089

• 1099

In the final example, what is the first step when subtracting 1405 and 326?

• Regroup from the thousands place

• Subtract the hundreds place

• Subtract the tens place

• Subtract the ones place
