Here is the confusion my primary teachers (and myself) are having with attributes of a cylinder.

Sometimes on the cylinder we see that it has 2 faces, 2 edges, and 0 vertices. Other times we see that it is 0 faces, 0 edges, and 0 vertices. We can’t find a clear definition in the standards or anywhere else.

There are mixed messages with how to define a “face” in geometry, therefore,….confusion lies within cylinders!

First question regarding this:
*In 1st grade, students compose two-dimensional shapes or 3-D shapes (including right circular cylinders) to create a composite shape.
*2nd Grade, When we are discussing various attributes in 2.G.1, one of the attributes is the number of faces. However, a cylinder is not mentioned in this specific standard.

Insights? How does CC define faces and attributes of cylinders?
Feeling like I need a better understanding of this progression and the expectations for this topic.
