Role

Adult ordinary model; exposed solution separate from genuine blank own work

Complete source

Day 56 ordinary 468+□=725 cards target.

Full alternative

An adult part-whole model uses 725 fictional cards as the whole. The known part is 468; the further part is initially shown with a box. The separate adult key gives 257, with 468+257=725. The two bar widths are proportional to 468 and 257. This labelled adult model must not be used as a genuinely empty own aid or an unseen held source.
