I noticed in the video that the teacher used the same symbolism used in "factorization" for her Common Core addition.

That is, aren't children still taught "factor trees" for multiplication:

6
/ \
6 1

The teacher used it for addition:

6
/ \
1 5

That alone might confuse the younger children.

That’s a really good point.
