New @openmiddle histogram ex: Using digits 0-9 no more than 1x each, fill in the blanks to make true statements. Bar heights also modifiable.

These Central Tendency puzzles from @MarkChubb3 remind me of skyscraper puzzles (just not as visual) but I think that being able to solve these would be a great indicator that they are starting to understand central tendency.

I can't help it, I have a soft spot for anything to do with the quadratic formula (those who know me, know why). But I do appreciate how he incorporates the visual version of what completing the square is.
