Overview of State Standards for Kindergarten
Whole numbers (Numbers, Operations)
Students begin to develop basic notions of numbers and use numbers to think about objects and the world around them. They practice counting objects in sets, and they think about how numbers are ordered by showing the numbers on the number line. As they put together and take apart simple numbers, students lay the groundwork for learning how to add and subtract. Understanding numbers is perhaps the most central idea in all of mathematics, and if students build and maintain a strong foundation of number sense and number skills, they will be able to succeed with increasingly sophisticated numerical knowledge and skills from year to year.
Patterns and operations (Operations, Algebra)
Students learn what it means to add and subtract by joining and separating sets of objects. Working with patterns helps them strengthen this understanding of addition and subtraction and moves them toward the important development of algebraic thinking. Students study simple repetitive patterns in preparation for increasingly sophisticated patterns that can be represented with algebraic expressions in later grades.
Objects and their locations (Geometry/Measurement)
Students develop basic ideas related to geometry as they name simple two- and three-dimensional figures and find these shapes around them. They expand their understanding of space and location by describing where people and objects are. Students sort and match shapes as they begin to develop classification skills that serve them well in both mathematics and reading—matching numbers to sets, shapes to names, patterns to rules, letters to sounds, and so on.
Additional Content (Geometry/Measurement)
Students informally develop early measurement concepts. This is an important precursor to Core Content on measurement in later grades, when students measure objects with tools. Solving measurement problems connects directly to the student’s world and is a basic component of learning mathematics.
Reasoning, problem solving, and communication
Students begin to build the understanding that doing mathematics involves solving problems and discussing how they solved them. Problems at this level emphasize counting and activities that lead to emerging ideas about addition and subtraction. Students begin to develop their mathematical communication skills as they participate in mathematical discussions involving questions like “How did you get that?” and “Why is that true?”

On-Line Math Expressions Resources
Log on to the Math Expressions web site to access the student activity book using the login/password combination given to you by your child’s teacher. If you have questions about accessing the material there, look at our FAQ page and see if your question is answered there. If not, contact the math support volunteer listed on the FAQ page. Other Math Expressions material including the unit summaries, mathematical background, a glossary, and family letters are available at the publisher’s Education Place website. You do not need a login in to access these materials.

Get the details of the current Kindergarten Washington State Standards (updated 2008) either in a pdf document or at the Office of Superintendent of Public Instruction (OSPI) on-line site.
Helpful/Fun External web sites for Kindergarteners
We haven’t had any recommendations for good math web sites for Kindergarteners yet. If you have a web site to recommend and want to provide a review (approximately 3-4 sentences), please let us know at mathhelp@misd.wednet.edu. We will only post the best sites that we can find (maximum of three for each grade).
