Here is a scan from an old Soviet textbook for school children:
It shows the table of quarks and antiquarks of different generations, colours, spins. The book also includes similar tables of gluons and their interactions with quarks and between themselves. They all are coded in this fancy cake-shape code.
The standard model table includes Z and W-bosons, gluons as well as graviton and gravitino.
What do you think about such manner of teaching physics and in general, what do you think about appropriateness of teaching Standard Model in junior school?

Tha book has chapters about quantum chromodynamics, spontaneous symmetry breaking, quantum parity and so on.
