That would be pretty awesome. It might be (relatively) easy to allow
collaborative creation of tiles, with each child's display showing
their own "creator" screen, but a shared collection of tiles. Whether
or not that would be clear enough to be usable is another question. I
suppose the tiles would/could be colored according to their creator
while in create mode, which would certainly help.

This problem is fairly easy to solve technically, but actually rather
advanced to expose to kids in the creation UI. It requires identifying
equivalence classes of pairs (one equivalence class, as per your
example, would contain both (2+2, 4) and (1+3, 4)). The pairs in these
equivalence classes many or may not be ordered, which would be another
complex choice to require of the user. That is, 1+3 = 2+2, but it is
likely the intent of the creator to always match an expression to a
value. An equivalence class defined having pairs (2+2, 4) and (4, 1+3)
is "correct" mathematically, but would still yield unexpected matches
Alternatively, the items in the equivalence class could be treated
individually instead of in pairs, eg. (2+2, 1+3, 4, 4), in which case
any item in the class can be matched to any other. This, again, may
not actually be desired.
