Worksheet focused on writing whole numbers in three equivalent representations: word form, standard form, and expanded form. Part A converts given numbers into word form, Part B rewrites numbers as sums of place values, and Part C converts spelled numbers back into standard form. Includes a chart-based challenge that requires filling all three forms, plus a clue-based challenge using specific digits exactly once to construct a valid 6-digit number, followed by word and expanded forms. An answer key supports self-checking.
