1.MD.A.1 Measure Lengths indirectly and by iterating length units.  
Order three objects by length: compare the lengths of two objects
indirectly by using a third object.

Up Order It 
1.MD.A.2 Measure lengths indirectly and by iterating length units.  
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.

Organize, represent, and interpret data with up to three categories; ask
and answer questions about the total number of data points, how many in
each category, and how many more or less are in one category than
another.
