STEP-BY-STEP SOLVED EXAMPLES

Example 1: Round 33 to the nearest ten

To round 33, first look at the digit in the ones place, which is 3. Since 3 is less than 5, we follow the rule to "round down." This means we keep the tens digit (3) exactly the same and change the ones digit to 0. Therefore, 33 rounds to 30.

Example 2: Round 45 to the nearest ten

Check the digit in the ones place, which is 5. According to the standard math rule, if the digit is 5 or greater, we "round up." To do this, we increase the tens digit (4) by one to become 5 and change the ones digit to 0. Thus, 45 rounds up to 50.

Example 3: Round 87 to the nearest ten

Identify the digit in the ones place, which is 7. Since 7 is greater than 5, we must round up. The tens digit (8) increases to 9, and the ones digit is replaced with a 0. So, 87 rounds to 90.

TEACHER & PARENT TIPS

When teaching rounding, introduce the "rounding hill" visual aid: numbers 1 through 4 stay at the bottom of the hill (round down), while numbers 5 through 9 slide down the other side (round up). Encourage students to underline the tens place and circle the ones place to help them focus their attention on the correct digits. For tactile learners, using a physical number line can help them see which "ten" the number is actually closer to. Consistent practice with these 60 problems will help build the fluency needed for standardized testing and real-world estimation tasks.
