Here's what I know

A scalar is tensor of order 0, a vector has order 1, and a matrix has order 2

Also I think I remember seeing something about how tensors can always be transformed to a different frame but retain some property? This is consistent with all the transformations we do on these matrices. But, is the fact that they are symmetric matrices that can be transformed to different basis the reason why they are tensors?
