About these worksheets
These worksheets build number sense by having students convert between word form and numeric form. Problem sets range from writing numbers through 120 for first graders up to reading and writing numbers through one million and decimals to thousandths for fourth and fifth graders. Activities also include writing numbers using tens and ones, converting between multiple forms, and writing simple equations from word form.

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.
