and taking from.

• Know the number names and the count sequence.

1. Count to 100 by ones and by tens.
* Illustrative Question from ClassK12 Kindergarten

K.CC
K.CC.2
K.CC.3
• Know the number names and the count sequence.
www.classk12.com4
1. Count forward beginning from a given
number within the known sequence (instead
of having to begin at 1).
2. Write numbers from 0 to 20. Represent a
number of objects with a written numeral 0‐
20 (with 0 representing a count of no
objects).

K.CC
K.CC.4a
K.CC.4b
K.CC.4c
www.classk12.com5
1. Understand the relationship between
numbers and quantities; connect counting to
cardinality.
a)  When counting objects, say the number
names in the standard order, pairing each
object with one and only one number name
and each number name with one and only
one object.
b)  Understand that the last number name
said tells the number of objects counted. The
number of objects is the same regardless of
their arrangement or the order in which they
were counted.
c)  Understand that each successive number
name refers to a quantity that is one larger.

K.CC
K.CC.5

1. Count to answer “how many?” questions
about as many as 20 things arranged in a
line, a rectangular array, or a circle, or as
many as 10 things in a scattered
configuration; given a number from 1–20,
count out that many objects.

K.CC
K.CC.6
• Compare Numbers.
www.classk12.com7
1. Identify whether the number of objects in
one group is greater than, less than, or equal
to the number of objects in another group,
e.g., by using matching and counting
strategies.1

K.CC
K.CC.7
• Compare Numbers.
www.classk12.com8
1. Compare two numbers between 1 and 10
presented as written numerals.

K.OA

K.OA.2
and taking from.
Illustration: Subtraction(OA)
www.classk12.com9
1. Represent addition and subtraction with
objects, fingers, mental images, drawings2,
sounds (e.g., claps), acting out situations,
verbal explanations, expressions, or
equations.
2. Solve addition and subtraction word
problems, and add and subtract within 10,
e.g., by using objects or drawings to
represent the problem.

K.OA
K.OA.3
and taking from.
Illustration: Addition(OA)
www.classk12.com10
1. Decompose numbers less than or equal to 10
into pairs in more than one way, e.g., by
using objects or drawings, and record each
decomposition by a drawing or equation
(e.g., 5 = 2 + 3 and 5 = 4 + 1).

K.OA
K.OA.4
K.OA.5
and taking from.
Illustration: Addition(OA)
www.classk12.com11
1. For any number from 1 to 9, find the number
that makes 10 when added to the given
number, e.g., by using objects or drawings,
and record the answer with a drawing or
equation.
2. Fluently add and subtract within 5.

K.NBT
K.NBT.1
Number and Operations in Base Ten
• Work with numbers 11–19 to gain foundations for place value.
Illustration: Addition (NBT)
www.classk12.com12
1. Compose and decompose numbers from 11
to 19 into ten ones and some further ones,
e.g., by using objects or drawings, and record
each composition or decomposition by a
drawing or equation (e.g., 18 = 10 + 8);
understand that these numbers are
composed of ten ones and one, two, three,
four, five, six, seven, eight, or nine ones.

K.MD
K.MD.1
K.MD.2
• Describe and compare measurable attributes .
Illustration: Measurement and Data (MD)
www.classk12.com13
1. Describe measurable attributes of objects,
such as length or weight. Describe several
measurable attributes of a single object.
2. Directly compare two objects with a
measurable attribute in common, to see
which object has “more of”/“less of” the
attribute, and describe the difference. For
example, directly compare the heights of
two children and describe one child as
taller/shorter.

K.MD
K.MD.3
• Classify objects and count the number of objects in each category.
Illustration: Measurement and Data (MD)
www.classk12.com14
1. Classify objects into given categories; count
the numbers of objects in each category and
sort the categories by count.

K.G
K.G.1
K.G.2
K.G.3
Geometry
• Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders,
and spheres).
Illustration: Geometry (G)
www.classk12.com15
1. Describe objects in the environment using
names of shapes, and describe the relative
positions of these objects using terms such
as above, below, beside, in front of, behind,
and next to.
2. Correctly name shapes regardless of their
orientations or overall size.
3. Identify shapes as two‐dimensional (lying in
a plane, “flat”) or three‐dimensional
(“solid”).

K.G
K.G.4
Geometry
www.classk12.com16
1. Analyze and compare two‐ and three‐
dimensional shapes, in different sizes and
orientations, using informal language to
describe their similarities, differences, parts
(e.g., number of sides and
vertices/“corners”) and other attributes
(e.g., having sides of equal length).

K.G
K.G.5
Geometry
www.classk12.com17
1. Model shapes in the world by building
shapes from components (e.g., sticks and
clay balls) and drawing shapes.

K.G
K.G.6
Geometry
www.classk12.com18
1. Compose simple shapes to form larger
shapes. For example, “Can you join these
two triangles with full sides touching to make
a rectangle?”
