About these worksheets

Students practice converting numbers between expanded form and standard (numeric) form. Worksheets cover whole numbers within 1,000 up to one million, as well as decimals to thousandths. Activities include standard expanded form (like 400 + 30 + 2) and expanded notation (using multiplication by place value). These resources align with second through fifth grade place value standards.
