Arrows Puzzle from Puzzle Box, Volume 1

This week, I'm trying out a different sort of puzzle on the puzzle table. Instead of being a puzzle where students have to arrange various laminated pieces like I frequently use, this is a coloring puzzle. To make things easier on students, I placed the puzzle inside an 11 x 17 dry erase pocket (affiliate link).

This puzzle, written by Erich Friedman, is featured in Puzzle Box, Volume 1 by Dover Publications (affiliate link).

My students have seemed a bit intimidated by this puzzle this week, so I'm wondering if I need to rewrite the instructions somehow. The goal of the puzzle is to color a subset of the given arrows so that each uncolored arrow points at exactly one other uncolored arrow and each colored arrow points at exactly two other colored arrows.

Some of my students who are regulars at the puzzle table read the instructions and immediately decided this puzzle was not for them without even attempting it. I'm wondering if the coloring aspect is part of the issue. If I laminated and cut out different colored/uncolored arrows that students could place on the puzzle board, would they be more willing to give the puzzle a try?

During my planning period today, I sat down with a student who often hangs out in my room during my planning period (he has a free hour), and solved this puzzle with him. Once I read the instructions and re-explained what it meant for an arrow to point at other arrows, he was able to pretty much solve the puzzle with only a tiny bit of guidance from me.

This makes me think that this puzzle would make a better class-wide challenge than a puzzle table challenge which is more of a tackle-it-on-your-own-if-you-are-so-inclined challenge.

Interested in this puzzle for your classroom? I've uploaded the file here. It's designed to print on 11 x 17 paper, but you can easily print it scaled to ~65% to print it on letter sized paper.
