Sample Scope and Sequence 2  a curriculum guide developed by the Charles A. Dana Center as part of the Common Core Tool Box
Unpacked Math Standards  this North Carolina document gives details and examples for each of the content standards and math practices at K level.
Kansas Common Core Flipbook for Kindergarten  this "flipbook" from the Kansas Association of Teachers of Mathematics is fantastic! It deeply describes the standards individually and provides sample problems, student misconceptions, and connections to other related standards (progressions).
Collection of K2 Mathematics Tasks  a collection of highquality tasks that align with the approach of the Common Core (thanks to the Albuquerque Public Schools!)  The acronym for the strand (or topic) of each task is described at the bottom of the page.
Illustrative Mathematics  for each of the domains of K8 math, you can click to reveal the common core standards and then click "see illustrations", which provides a list of rich math tasks that cover these concepts.
Balanced Assessment in Mathematics Program  a program out of Harvard that has compiled loads of highquality assessment tasks, K12. Go to the K2 set of assessments here.
NSDL Collection of Common Core Math for K  this page contains a digital collection of math related resources, lessons, websites and games by math standard for Kindergarten.

Learning Trajectories of the Standards  click on the hexagon image here and you can find the learning trajectories (the standard developed across grade levels) for your students within each of the domains.
Assessments:
The Utah Education Network has a great page of K resources  each of the standards domains has a links button that will take you to performance tasks and activities for your students that emphasize critical thinking connected to the CCSS.
Basic number, order, relationship and pattern test  computer based test in a pdf form, read aloud to the student
