What This Standard Means
What Students Need to Do
- Students read large whole numbers by grouping digits into periods. They write the same number in standard, expanded, and word forms while keeping zeros in the correct places.
What Mastery Looks Like
- Students accurately convert a number among standard, expanded, and word forms. They preserve placeholder zeros and explain each digit’s value based on its position.
Common Misconceptions
- Students may leave out zeros that hold a place, writing 46,72 for 406,072. They may confuse a digit with its value or misread periods such as thousands and millions.
How to Assess It
- Give students 508,036. Ask them to write it in word form and expanded form, then circle the digit worth 8,000.
