Standard
Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.
Student Language:
- "I can tell the length of an object using whole numbers."
- "I can show that I understand how to measure something by using a smaller object as a measurement tool."
