Grade 1: Measurement and Data
Partially coveredOrder three objects by length; compare the lengths of two objects indirectly by using a third object.
Partially coveredExpress 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.
