I am unclear about whether this standard requires the introduction of coordinates and the coordinate plane. Should students have been introduced to this in a prior level or is it to be covered in this standard? Many thanks.
Note the geometry standards for grade 5 in the cluster “Graph points on the coordinate plane to solve real-world and mathematical problems.” These appear in the CCSS document after the grade 5 OA standards, but that is not meant to indicate that they necessarily appear later in instruction.
