Rounding to the Hundreds Practice Set for First Grade
A short practice packet that teaches 1st graders to round numbers to the nearest hundred by finding the midpoint between benchmark hundreds on a vertical number line. It includes a worked example (rounding 240) and a guided "Try it together" section where students use number lines to round numbers like 120.

Teacher Guide & Tips
- Use this as a guided small-group or whole-class lesson, starting with the worked example of 240 and walking through why the midpoint of 250 determines the rounding.
- Discussion question: "How do we know which hundred 240 is closer to, and what would change if the number were 260?"
- Scaffold for struggling readers: have students first identify the two benchmark hundreds on the number line, then locate the midpoint with your help before trying to round the target number.
- Extension for advanced students: ask them to round a three-digit number like 385 or 470 and explain their reasoning using the midpoint.
- Estimated time: about 30 to 40 minutes, including the example walkthrough and the guided practice problems.
