Measurement and Data 1.MD 2.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. //
 * Measure lengths indirectly and by iterating length units. **
