You can map it out ahead of time with tape, or let them take control.
Language like, "I spy a square!" brings attention to the shapes that they are creating. Turn it into a game when they are done. "Jump three times on the red triangle!" (see what we did there?) It's not "learning" if it's fun and interest based, right?
Our advice- keep it light- and follow their lead. Chances are... they'll be intentionally creating shapes in their next design!
