This practice set gives students focused practice with number names, place value, and rounding for both whole numbers and decimals. Students convert between written number names and standard form, identify digits in specific decimal place values, and round multi-digit numbers and decimals to various places including the nearest million, thousand, integer, tenth, and hundredth. A final problem asks students to reason backward from a rounded value to possible original numbers, reinforcing conceptual understanding of rounding intervals rather than just procedural rules.

A complete answer key supports quick grading and student self-checking. The mix of multiple-choice and short-answer items makes this resource easy to use as a quick skills check, in-class practice, or a targeted review for students who need extra reinforcement with place value and rounding in a Pre-Algebra or Algebra I setting.
