This page provides sample downloads from some of the resources in Kindergarten Mega Math Bundle aligned with the Kindergarten Common Core State Standards for Counting and Cardinality, Operations and Algebraic Thinking, and Number and Operations in Base Ten. Try some of the samples listed in blue below each standard or download the bundle and have instant access to hundreds of easy-prep, engaging resources to simplify your math lesson planning and make active engagement through hands-on math instruction an integral part of your kindergarten classroom.
COUNTING AND CARDINALITY
Know number names and the count sequence
K.CC.A.1 Count to 100 by ones and tens.
Samples from:
Samples from:
K.CC.A.2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
K.CC.A.3 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.CC.B.4 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.
Samples from:
Samples from:
K.CC.B.5 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.
Samples from:
Samples from:
K.CC.C.6 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.
Samples from:
Samples from:
K.CC.C.7 Compare two numbers between 1 and 10 presented as written numerals.
OPERATIONS AND ALGEBRAIC THINKING
Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.
K.OA.A.1 Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
Samples from:
Samples from:
K.OA.A.2 Solve addition and subtraction word problems, and add and subtract within 10, e.g. by using objects or drawings to represent the problem.
Samples from:
Samples from:
K.OA.A.3 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).
Samples from:
Samples from:
K.OA.A.4 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.

K.OA.A.5 Fluently add and subtract within five.
NUMBER AND OPERATIONS IN BASE TEN
Work with numbers 11-19 to gain foundations for place value.
K.NBT.A.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.
