Brainteaser: Answer


Without lifting your pencil off of the page, draw
four straight lines that pass through each of these 9 dots once and only once.

Debriefing after activity: This problem is difficult because we assume that we can only draw lines within the perimeter created by the dots.

This is analogous to jazz music because jazz musicians thought "outside the box" about what could happen musically and it was shocking and surprising to society at first, because it just never even occurred to them to try music in that way.
