# According to Common Core standards, what math skills are beginning Kindergarteners supposed to have?

I remember looking once at what chikdren in Kindergarten were expected to know, and it was quite a bit. I have a young son, and would like to know:

What is a Kindergartener expected to know about numbers and shapes and other mathematical concepts?

Counting and Cardinality

• Know number names and the count sequence.
• Count to tell the number of objects.
• Compare numbers.

Operations and Algebraic Thinking

• Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.

Number and Operations in Base Ten

• Work with numbers 11-19 to gain foundations for place value.

Measurement and Data

• Describe and compare measurable attributes.
• Classify objects and count the number of objects in each category

Geometry

• Identify and describe shapes.
• Analyze, compare, create, and compose shapes.

Mathematical Practices

• Make sense of problems and persevere in solving them.
• Reason abstractly and quantitatively.
• Construct viable arguments and critique the reasoning of others.
• Model with mathematics.
• Use appropriate tools strategically.
• Attend to precision.
• Look for and make use of structure.
• Look for and express regularity in repeated reasoning.

I am not aware of incoming requirements for Kindergarten but the link above details the learning goals for CC math at grade K.

• May I suggest that you make the answer more self-contained by summarizing how the link answers the question. Commented Mar 14, 2014 at 1:22

Here is a github page that details connections between all standards: CCSSM Flow View

For example, you can hover over the standards for K and see how they relate to others. Moreover, you can click through to see the description of the standard, its prerequisites, and its dependent strands.

Site description:

Hover over a standard to see what it depends on (blue) and what depends on it (red). The colors fade as the dependency chain to the standard becomes longer. Click on a standard for more detail on the standard and its prerequisites and dependent standards. The dependencies are derived from a shared spreadsheet, referenced from a document by Jason Zimba.

Hopefully this helps clarify both what is to be known for CCSSM, and also how the covered material will be built upon in subsequent years.
