1Round 472 to the nearest 10.

A.470

B.480

C.500

D.462

Explanation: To round 472 to the nearest 10, look at the ones digit. The ones digit is 2, which is less than 5, so round down. The tens digit stays the same. 472 rounds to 470.

2Round 847 to the nearest 100.

A.800

B.850

C.900

D.840

Explanation: To round to the nearest 100, look at the digit in the tens place. In 847 the tens digit is 4, which is less than 5, so the hundreds digit stays 8 and the smaller places become zero. 847 rounds to 800.

3What is the value of the digit 5 in the number 358?

A.50

B.5

C.500

D.58

Explanation: In 358, the digit 5 is in the tens place. The value of a digit in the tens place is that digit times 10. So the value of 5 is 5 × 10 = 50.

4Round 736 to the nearest 100.

A.700

B.800

C.740

D.730

Explanation: To round 736 to the nearest 100, look at the tens digit. The tens digit is 3, which is less than 5, so round down. 736 rounds to 700.

5Which number rounds to 600 when rounded to the nearest 100?

A.562

B.549

C.650

D.672

Explanation: Rounding to the nearest 100 depends on the tens digit. In 562 the hundreds digit is 5 and the tens digit is 6, and because 6 is 5 or greater, the number rounds up to 600. Every whole number from 550 through 649 rounds to 600.

6Add: 458 + 323 = ?

A.781

B.771

C.780

D.782

Explanation: Add the ones: 8 + 3 = 11, write 1 carry 1. Add the tens: 5 + 2 + 1 = 8. Add the hundreds: 4 + 3 = 7. The sum is 781.

7Subtract: 800 - 345 = ?

A.455

B.555

C.445

D.545

Explanation: Subtract the ones: 0 - 5 requires borrowing. Borrow from the tens, but tens is 0, so borrow from the hundreds. 800 becomes 7 hundreds, 9 tens, 10 ones. 10 - 5 = 5. 9 - 4 = 5. 7 - 3 = 4. The difference is 455.

8Add: 567 + 289 = ?

A.856

B.746

C.855

D.756

Explanation: Add the ones: 7 + 9 = 16, write 6 carry 1. Add the tens: 6 + 8 + 1 = 15, write 5 carry 1. Add the hundreds: 5 + 2 + 1 = 8. The sum is 856.

9Subtract: 903 - 478 = ?

A.425

B.525

C.475

D.435

Explanation: Subtract the ones: 3 - 8 requires borrowing. Borrow 1 ten from the tens place (0), which borrows from the hundreds. 903 becomes 8 hundreds, 9 tens, 13 ones. 13 - 8 = 5. 9 - 7 = 2. 8 - 4 = 4. The difference is 425.

10A store has 245 apples and 318 oranges. How many pieces of fruit are there in all?

A.563

B.553

C.564

D.463

Explanation: Add the two quantities: 245 + 318. Ones: 5 + 8 = 13, write 3 carry 1. Tens: 4 + 1 + 1 = 6. Hundreds: 2 + 3 = 5. The total is 563 pieces of fruit.

North Dakota A+ Mathematics Grade 3 Study Tips from Top Performers

1Master multiplication and division facts within 100 fluently, then apply them in two-step word problems.

2Place fractions on a number line to build the meaning of a fraction as a number, not just parts of a shape.

3Distinguish area (covering) from perimeter (distance around) using real rectangles.

4For data items, read the scale on bar graphs carefully before comparing quantities.

5Always check the units (minutes, centimeters, liters) in measurement word problems.
