Resources:
Scope and Sequence  CESA #7 developed curriculum map for teaching the Common Core Standards in Math
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 the 3rd grade level.
Kansas Common Core Flipbook for 3rd Grade  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 35 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.
Inside Mathematics  extensive resource from the Noyce Foundation that provides videos of example lessons from many grade levels (although they don't have any specific to 3rd yet). There is also a fantastic third grade page of resources, including math tasks by standard.
Balanced Assessment in Mathematics Program  a program out of Harvard that has compiled loads of highquality assessment tasks, K12. Go to the set of 35 assessments here, or to the K2 set of assessments to support struggling students.
NSDL Collection of Common Core Math for 3rd Grade  this page contains a digital collection of math related resources, lessons, websites and games by math standard for 3rd grade.
Standards for Mathematical Practices in Third Grade  scroll down to details on how these practices can be integrated in 3rd grade math instruction. A district in Utah has produced posters of each of the math practices modified for each grade level K6, with examples.
SECC Videos for Understanding the CCSS in Math in 3rd Grade  series of videos designed to clarify the meaning of individual standards by discussing the language of the standard and giving an example problem (has K12 videos available).
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:
Computerbased items released from Smarter Balanced  there have been a set of computerbased items released that you can go through and actually answer online. If you go to the top of the page you can select, "view more sample items" to see a list of sample questions by grade level. You can also select "about this item" at the top to see which specific standards connect to the test item.
