Rounding to Nearest 100 & 10 Within 1,000 on a Number Line Rounding Worksheets

How did you learn to round numbers? Did you learn a rhyme like, “Four or less, let it rest. Five or more, add one more?” A quick search online for rounding rules will result in loads of cute rhymes and tricks for rounding. But rhymes and tricks don’t teach our students the true meaning of rounding.

I’d like to encourage you to stop teaching the rounding rhymes and focus on real, conceptual understanding with your students. Remember that the goal is deep understanding and number sense development, not simply getting a correct answer quickly.

Using Number Lines for Rounding Numbers

When we use number lines to round numbers, we allow our students to see how rounding works, which allows them to truly understand it. When you place benchmark numbers and midpoints on a number line, it becomes clear which benchmark a number is closest to!

This resource will provide scaffolding to students as they learn the process of rounding on a number line.

✅ In the Learning to Round section, students will learn about benchmark numbers, how to find midpoints, and how this can help them round to the nearest hundred.

✅ In the Practice and Reinforcement section, students will be provided with opportunities to practice what they have learned and use their new rounding knowledge.

⭐️⭐️ BONUS SECTION

The focus of this resource is on rounding to the nearest hundred within 1,000. However, there is also a BONUS SECTION included for rounding to the nearest ten within 1,000.
