This page provides examples of Kindergarten Number Activities aligned with the Common Core State Standards. All activities are suitable for use in Math Centers, small group or whole class settings and are designed to provide opportunities for students to communicate their reasoning and mathematical thinking. All files for the Kindergarten Number Activities listed are in PDF format and can be accessed using Adobe Reader.
KINDERGARTEN MATH ACTIVITIES: COUNTING AND CARDINALITY
K.CC1 Count to 100 by ones and by tens.
K. CC2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
K.CC3 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).
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 1-20,
count out that many objects.
Math Read Aloud Task Cards:
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
Greater Than/Less Than
K.CC7 Compare two numbers between 1 and 10 presented as written numerals.
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.
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.
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)
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.
KINDERGARTEN MATH ACTIVITIES: NUMBERS AND OPERATIONS IN BASE TEN
Work with numbers 11-19 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.
