Volume 1: Japanese Logic Puzzles For The Secondary Math Classroom
I left a teaser at the halt of yesterday's spider web log post service which likely wasn't the nicest matter to do. Sorry! :)
To grab you lot up, I posted most some awesome expanse in addition to book puzzles created yesteryear Naoki Inaba. You tin dismiss read that post service here. While researching those puzzles in addition to looking for possible online sources for them, I institute some on Mr. Inaba's website. This led me to commence wondering, "What sort of other puzzles has he created?"
So, ever-curious me, decided to see the balance of the website. Of course, it's all written inwards Japanese. But, alongside plenty random-clicking, I was able to stumble across some to a greater extent than math-y logic puzzles that I can't hold back to contain inwards my math classroom. The instructions are inwards Japanese, but the math of the puzzle is universal.
So, let's play a game. Here are the rules:
1. I'll post service a moving-picture demonstrate of a puzzle in addition to the solution. The instructions are inwards Japanese.
2. Determine the finish of the puzzle.
3. Figure out how you lot could purpose it inwards your math classroom.
4. Scroll downward in addition to run across if your thoughts jibe mine!
Sound fun? Let's Begin!
These are all master copy puzzles created yesteryear Naoki Inaba in addition to posted for costless on his website. There are quite a few that I run across math-y applications of, then I'll endure splitting them into multiple posts over the side yesteryear side few days.
Puzzle 1:
Inaba calls these K-Maze Puzzles.
From my puzzle-studying, I've determined that these are angle puzzles. S stands for Start. G stands for Goal. Draw a path from south to G then that the path passes through each circle alongside the angle mensurate specified yesteryear the puzzle.
[Full Disclosure: I don't know whatever Japanese unless you lot count the summertime our Vacation Bible School was Nippon themed. If I've made a false assumption, delight right me inwards the comments!]
Google Translate translates this every bit "Angle Maze." The PDF file of these puzzles contains an illustration of a incorrect solution. So, I'm too assuming that you lot tin dismiss alone go through each circle once.
This PDF contains 38 of these puzzles which larn progressively harder. Here are the solutions.
If you lot similar this sort of angle puzzle, Inaba too has a dissimilar version where you're non told where to commence or end. Instead, you're simply told precisely which points you lot MUST become through. You tin dismiss uncovering iv of those puzzles here.
I intend these would endure a nifty warm-up for a geometry class!
Puzzle 2:
Inaba calls these Sankaku Puzzles.
These are expanse puzzles. See that release 3 side yesteryear side to those characters? That tells you lot to brand a triangle that goes through a subset of those points alongside an expanse of 3.
I intend the associated instructional images inwards the PDF file for these puzzles are beautiful. I'm non going to insert them hither because I actually practice desire you lot to become in addition to banking concern check them out!
Google Translate translates this puzzle championship every bit "Looking Triangle." Not quite certain what that's about...
The PDF file provides you lot alongside 42 of these to boot the bucket on you lot (or your students) busy. There are too solutions so you lot tin dismiss banking concern check your operate along the way. Since the directions are inwards a unusual language, I endeavour to banking concern check my operate alongside the solutions Influenza A virus subtype H5N1 LOT simply to brand certain I haven't made whatever incorrect assumptions most the rules of the puzzle.
These would endure nifty for practicing/reviewing finding the expanse of a triangle.
Puzzle 3:
Inaba calls this puzzle "Kazu."
I receive got to admit, these puzzles are a chip trickier for me to decode. See that ii below the puzzle? That tells you lot that you lot require to practice a foursquare that holds precisely ii apples. I idea they were pumpkins at first, but Google Translate told me otherwise. As for the championship of this puzzle, Google Translate says it's "Looking for Kaz."
You too require to know that your foursquare must endure 3 x 3. How are you lot supposed to know that? If you lot expect closely at the text higher upwardly the puzzles, you'll run across the release 3 appear twice.
The PDF file for this puzzle contains 42 dissimilar puzzles, but I've alone figured out how to solve the commencement 24. Starting alongside puzzle 25, at that spot are apples in addition to oranges inwards the puzzles. And the numbers become away. If soul figures out how to practice the subsequently puzzles, delight allow us know inwards the comments below! If you lot desire to banking concern check your assumptions, hither are the solutions.
I intend these puzzles would brand a nifty warm-up. They would too endure nifty to set within a dry erase pocket (affiliate link) in addition to give to students who complete early on in addition to require something to boot the bucket on their brains stimulated.
Okay. That's plenty for Volume 1. Come dorsum tomorrow for iii to a greater extent than puzzles!
