Round Decimals to the Nearest Tenth

Have your child underline the digit in the rounding place and circle the digit to its right before deciding. When an answer looks wrong, sketch the two possible answers on a number line and place the number between them. Check with the answer key.

Round decimals to the nearest tenth with a number line check. To round to the nearest tenth, look at the hundredths digit. If it is 5 or more, round up. If it is 4 or less, keep the tenths digit. The directions on the page read: Round each number to the nearest tenth. Then, check which tenth is closer. Finish every problem. The page opens with a worked example, and the answer key shows every answer.

Yes, both. We made it for 5th Grade decimals, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with rounding decimals and number lines. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Look at the hundredths digit. If it is 5 or more, round the tenths digit up; if it is 4 or less, keep it. 3.46 rounds to 3.5 because the hundredths digit is 6.

The number line shows which tenth or hundredth the number is actually closer to, so the rule makes sense instead of feeling like magic. 5.683 sits nearer 5.68 than 5.69.

Zoom in between two hundredths, like 5.12 and 5.13, and split the space into 10 equal parts. Each part is 0.001, so the 4th mark is 5.124.

The rounding pages support CCSS 5.NBT.A.4 (round decimals to any place) and the number line page supports 5.NBT.A.3 (read and compare decimals to thousandths).

5th graders read, write, compare and round decimals to thousandths (CCSS 5.NBT.A.3 and 5.NBT.A.4), understand place value patterns and powers of 10 (5.NBT.A.1 and 5.NBT.A.2), and add, subtract, multiply and divide decimals to hundredths (5.NBT.B.7).

Start with place value to thousandths, then comparing, ordering and rounding. Move to adding and subtracting, then multiplying and dividing. Finish with word problems, mixed operations and a unit review. The subtopics on this page follow that order.

Estimate first. Rounding each number to a whole number gives a ballpark answer, so 4.8 x 3.1 should be about 15, which rules out 1.488 and 148.8.

Yes. All 55 sheets have an answer key, and the two page sheets have a two page key.
