Rounding and Two-Digit Subtraction Progress Monitor
By Barbara G.
A large-print, 8-problem progress monitoring assessment for 3rd graders covering rounding to the nearest 10 and 100 (four problems) and two-digit subtraction with and without regrouping (four problems). Students work through number lines and short-response inputs, making it a quick check of place value and subtraction skills in a single sitting.

Teacher Guide & Tips
- Use as a short, stand-alone progress check at the end of a unit on rounding or two-digit subtraction, or as a baseline before instruction begins, in about 15 to 20 minutes.
- Discussion question after scoring: when you round 234 to the nearest 10, why does the digit in the ones place matter, and how does the number line help you decide?
- Scaffold for struggling readers: read each direction aloud, and let students use the open number line to count by tens or hundreds before writing their answer.
- Extension for advanced students: ask them to explain why 45 rounds up to 50 under the 5-or-more rule, or to write their own two-digit subtraction problem that requires regrouping and explain each step.
- Because the type is large and the number lines are unlabeled, print at full size and allow extra time for students who need to fill in endpoints themselves.
