Understand, read, write, and represent whole numbers from 0 through 1,000,000 in standard, expanded, and word forms, identifying each digit’s place and value through the millions place and using zeros as placeholders. Compare and order whole numbers, identify whole numbers between benchmarks, and locate them on scaled number lines using place-value reasoning and the symbols <, >, and =. Recognize ten times as much and one tenth as much through base-ten relationships, and round whole numbers through the millions place, including to the nearest 10, 100, and 1,000.
