Fluently Adding and Subtracting Numbers Greater Than 1000

Solve the following problem: 113,300-1,774

• 113,123

• 113,674

• 115,074

• 111,526

Subtract the following

• 2,222

• 2,122

• 2,215

Which of the following COULD be used to estimate the sum of 3,604 + 5,132? (MARK ALL THAT APPLY)

• 4,000 + 5,000 = 9,000

• 3,600 + 5,100 = 8,700

• 3,600 + 5,130 = 8,730

• 3,000 + 5,000 = 8,000

Round 6,425 - 371

• 6,054

• 5,700

• 6,000

Mrs. Krutak used 1,820 pencils last year. This year she thinks she will use 1,932 pencils. About how many pencils is that all together?

• 3,000.

• 3,700.

• 4,000.

• 3,752.

What is the estimated sum of

5,623 + 2,895?

Eric completed this subtraction problem.

40,932 - 17,584 = x

Then he rounded his answer to the nearest thousand.

What is Eric's answer?

• 23,000

• 22,000

• 23,348

• 23,300

Estimate the sum using rounding: 22,871 + 19,667 =

• 40,000

• 24,000

• 30,000

• 50,000

Estimate to the hundreds place.
7,538 + 2,317 = 

• 9,800

• 9,900

• 9,855

• 520

Round to the nearest thousand, then estimate the sum:

25,219 + 4,876

• 29,000

• 31,000

• 30,000

• 35,000
