There are generally four word forms that help students to understand place value in large numbers. Those are standard form (the way we usually write numbers with thousand groups), word form, short word form (a combination of numbers and words) and expanded number form. This worksheet displays a table that the student completes with the missing number forms. You can select the types of forms to use on the worksheet and the source type. To make the source form vary from problem to problem, select “random” as the form type.
