Understanding Tensor Notation $\chi\in\mathbb{R}^{I\times J\times K}$

Question

I'm very new to the world of Tensors, and feel like I am thinking about a specific notation very incorrectly. Say you have $$\chi\in\mathbb{R}^{I\times J\times K}$$ The way I have been thinking about a Tensor of this sort was as short video where say we have a sequence of say K=10 images which are all I=20 by J=20 pixels each. From this, I would imagine the tensor as a sequence of 10 matrices, which are each 20x20 in size. Is that correct? If not, is there a more intuitive way to think through the notation?
