About the Operations & Algebraic Thinking strand
The Operations & Algebraic Thinking strand — coded OA in the Common Core State Standards — runs through every grade level represented above. Each grade revisits the same big ideas with progressively more abstract numbers and richer contexts. That spiral is why a Grade 4 worksheet in this strand looks similar to a Grade 6 one on the surface, even though the underlying expectation has shifted considerably. For a deeper map of the standards in this strand, see the official CCSS Operations & Algebraic Thinking progression document.
Use the grade pills above to jump to the level you are teaching, or scroll the full list to see how the same topic shows up across the K-8 arc. We deliberately keep the printable layout the same across grades so students who already know our pages can focus on the math instead of re-learning a new format.
