What is Common Core?
"Common Core" refers to the Common Core State Standards (CCSS) that are used in many states in the U.S. There are Common Core standards for Mathematics and English. Here we focus on the Mathematics CCSS. For information about the standards and history of California's adoption of them, see the California Department of Education Common Core State Standards website.
How to Read and Identify Common Core Standards
The standards have changed and will continue to change, but what is important for now is simply being able to read and identify them. There is no way to know for sure what standards schools will be using in the future, so what we care about right now is being able to use them. Do not memorize any of them! So that we are all looking at the same set of standards, we will use the CCSS attached here.
While it is recommended that you read the full introduction to the standards, it is not required. What you definitely should look at is guide on page 5 showing all the components of the standards. Note that you do not have to memorize any of this (you can and should look up this information often), but instead focus on understanding and being able to tell the difference between a standard, a cluster, and a domain; how the standards are labeled, and how these components relate to the organization of standards.
Find standard 1.MD.3. Identify the standard, cluster, and domain.
Do this, then check your answer below.
Solution
This standard can be found on page 16 of the document. How did I find it? The 1 in 1.MD.3 means that it's a first grade standard. So, I went to the section of the document that covers first grade standards. The MD in 1.MD.3 is an abbreviation of the name of the domain that this standard is in. So, I looked for a domain name that would reasonably be abbreviated as MD. Sure enough, one of the domains is "Measurement and Data". The 3 in 1.MD.3 means that it's the third standard in the domain. The standard is reproduced below.
1.MD.3 Tell and write time in hours and half-hours using analog and digital clocks.
Note that the standard in the example is its own cluster, while 1.MD.1 and 1.MD.2 are in another cluster and 1.MD.4 is a third cluster (it is also by itself). Look at all four of these standards and see if you agree that they all belong in the domain Measurement and Data. See if you also agree that 1.MD.1 and 1.MD.2 belong in the same cluster while 1.MD.3 and 1.MD.4 belong in their own singular clusters.
