Logic Puzzle Love: Hashi Edition

One of the things I've most liked nearly introducing my students to novel logic puzzles is that they've been novel to me every bit well! I was initially hesitant to endeavor the hashiwokakero puzzles amongst my students because they sounded scary. I learned nearly these puzzles from reading the slides from Jeffrey Wanko's NCTM presentation. You tin banking enterprise check out the slides from his diverse presentations on using logic puzzles inward the math classroom here.

My kids preferred calling these "Bridge" puzzles. And, I'm totally okay amongst that. Though, I detect myself thinking of them every bit "Hashi" puzzles.

I seat puzzle Influenza A virus subtype H5N1 from this document on the SMARTBoard for us to solve together every bit a class. After working through it together amongst a few bumps along the way, I gave students their ain ii puzzles to solve. (Puzzles B in addition to C from the previously linked document).

Here are the rules:

• The bridges must start out in addition to terminate at islands, traveling inward a at 1 time work (horizontally or vertically)
• The bridges must non cross whatever other bridges or islands
• No to a greater extent than than ii bridges tin connect a distich of islands
• The full publish of bridges connected to each isle must agree the publish on that island

Several students decided these were their favorite logic puzzles yet. I allow 1 of my classes vote 1 twenty-four hours every bit to which puzzle they would similar a run a peril to produce again, in addition to these puzzles were a huge winner past times a landslide.

I spent a substantial business office of 1 planning catamenia playing these puzzles online at Nikoli.

Also - I works life a site amongst 10 weeks worth of logic puzzle lesson plans that I've been stealing problems from these past times few weeks. Here's the link.
