Counting on is not specifically mentioned as a

conceptually challenging for 1st graders as they are
still working on developing conservation of
number. It is not a “procedure” but the conceptual
underpinning for their understanding of the
number system.

according to length, capacity,
weight, and temperature by

objects using both

standard units of measure,
e.g., inches, centimeters.
Order three objects by length; compare the
lengths of two objects indirectly by using a third
object.

terms of using measurement units and
quantification, neither standard looks at the
indirect measure with reference to a third object.

(CCRSM)
1.MD.A.2
DoDEA Standards
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.
K.M.4d
Use non-standard
measurement tools to
estimate and verify results.
1.M.4c
Estimate and measure a
variety of attributes of objects
using standard and
nonstandard units.
Alignment Notes
DoDEA standards include more attributes and also
include estimation as part of the standard
statements. See also 2.M.4e: use repetition of a
single unit to measure something larger than the
unit.
For first graders, this is more than just “following a
procedure”. CCRSM is worded to move students
toward generalizing this concept of length (no
gaps, no overlaps) for its later critical application to
the number line, rational number understanding,
etc.
CLUSTER: Tell and write time.
1.MD.B.3
Tell and write time in hours and half-hours using
analog and digital clocks.
1.M.4e
Tell time to the hour and half
hour using digital and analog
timepieces.
Writing time is not specified in DoDEA standards.
CLUSTER: Represent and interpret data.
1.MD.C.4
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 in another.
1.M.5b
Collect, organize, represent,
and interpret data using
concrete objects, pictures,
tallies, and graphs.
1.M.5d
Construct questions and make
predictions that can be
answered by using
information from a graph or
table.
Alignment of DoDEA CCRSM with the DoDEA Academic Standards
DoDEA standards are broader, including data
collection and prediction. Data standards have
been reduced (in number and in level of
conceptual understanding) in order to allow for
more time in the instructional year to focus on
number, numeracy, the number system and the
meaning of addition/subtraction. Data and
