Common Core worksheet catalog

CCSS-aligned, not CCSS-stamped. Standards are numbered differently from state to state and country to country, and one sheet often spans several of them, so the codes live here instead of on the paper. This is our current Common Core to worksheet catalog — we are filling in the rest as we go.

The wording beside each code is our own short summary of what the standard asks for, not its official text. For that, see the Common Core State Standards Initiative.
