KINDERGARTEN MATH ACTIVITIES: COUNTING AND CARDINALITY
K. CC2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
Possible Activities: 
K.CC3 Write numbers from 0 to 20. Represent a number of objects with a written numeral 020 (with 0 representing a count of no objects).
Count to tell the number of objects
K.CC4 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.CC5 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 120,
count out that many objects.
Possible Activities: 
Math Read Aloud Task Cards:
Compare numbers
K.CC6
Identify whether the number of objects in one group is greater than,
less than, or equal to the number of objects in another group
Possible Activities:
Who Has More?
Who Has Less?
Show One Less
Greater Than/Less Than
K.CC7 Compare two numbers between 1 and 10 presented as written numerals.
Greater Than
Less Than
KINDERGARTEN MATH ACTIVITIES: OPERATIONS AND ALGEBRAIC THINKING
Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from
K.OA1
Represent addition and subtraction with objects, fingers, mental
images, drawings, sounds (e.g., claps), acting out situations, verbal
explanations, expressions, or equations.
Possible Activities: 
K.OA2 Solve addition and subtraction word problems, and add and subtract within 10, e.g. by using objects or drawings to represent the problem.
Possible Activities: 
K.OA3 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)
Possible Activities: 
Math Read Aloud Task Cards: 
K.OA4 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.
Possible Activities: 
K.OA5 Fluently add and subtract within five 
KINDERGARTEN MATH ACTIVITIES: NUMBERS AND OPERATIONS IN BASE TEN
Work with numbers 1119 to gain foundations for place value
K.NBT1
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.
