Free Iowa Test of Basic Skills (ITBS) 3rd Grade Questions and Answers

Question 1

What number, when rounded to the nearest hundred, is 678?

Accepted Answer

700

Answer

To round 678 to the nearest hundred, you look at the tens digit. Since the tens digit (7) is 5 or greater, you round up the hundreds digit. Therefore, 678 rounds up to 700.

Question 2

The Thompson family traveled 362 miles. What is 362 to the closest hundredth?

Accepted Answer

400

Answer

To round 362 to the nearest hundred, you examine the tens digit. Since the tens digit (6) is 5 or greater, you round up the hundreds digit. Thus, 362 rounds up to 400.

Question 3

How much is 946 when it's rounded to the closest hundred?

Accepted Answer

900

Answer

To round 946 to the nearest hundred, you observe the tens digit. Since the tens digit (4) is less than 5, you round down, keeping the hundreds digit the same and changing the tens and ones to zero. Therefore, 946 rounds down to 900.

Question 4

The number of competitors at a track meet was rounded up to the nearest ten by the trainer. There are 400 runners, rounded up. Which figure might represent the real number of competitors at the track meet?

Accepted Answer

397

Answer

If 400 is the number rounded up to the nearest ten, the original number must have had a ones digit of 5 or greater, and its tens digit would have been 9 (to round up to the next hundred). Among the options, 397 has a 7 in the ones place, which rounds 390 up to 400 when rounding to the nearest ten.

Question 5

Nathan "accidentaly" "spilled" the milk in his glass. Which of the following words is misspelled?

Accepted Answer

Answer

The word 'accidentaly' is misspelled; the correct spelling is 'accidentally.' It requires two 'l's before the 'y' to be grammatically correct. The other words in the sentence are spelled correctly.
