## Japanese Logic Puzzles for the Secondary Math Classroom

Recently, I posted about some awesome area and volume puzzles created by Naoki Inaba.  You can read that post here.  While researching those puzzles and looking for possible online sources for them, I found some on Mr. Inaba’s website.  This led me to start wondering, “What kind of other puzzles has he created?” So, ever-curious …

## Area Maze Puzzles from Naoki Inaba

Area Maze Puzzles from prolific Japanese puzzle creator Naoki Inaba have become quite popular in the United States. This hasn’t always been the case. I first learned about these puzzles from a tweet from Lisa Bejarano. At the time of her tweet, you could only really get your hands on a large number of area …

## Evaluating Functions Puzzle Activity

After making my Function (or Not) Puzzle to give students practice classifying relations as a function or not a function, I was eager to make a similar open middle style activity to practice a different skill. I settled on creating an evaluating functions activity that would give students practice evaluating functions and hopefully help them …

## Function vs Not a Function Puzzle Activity

I created this function vs not a function puzzle to help my students practice determining if a relation is a function or not a function.  I also wanted my activity to perform double duty.  I wanted students to be able to use the exact same activity to form relations that were functions and that were …

## Masyu Puzzles

I tried out some Masyu puzzles the other day with a group of students.  These are a new-to-me puzzle that I learned about from Jeffrey Wanko. Usually, I’m drawn to logic puzzles involving numbers.  (I’ve posted about KenKen, Futoshiki, Hashi, Shikaku, and Paint by Number puzzles before.)  But, these have no numbers involved.  Actually, there …

## Make It Even Brain Teaser

Last Friday, I pulled a this make it even brain teaser out for Figure It Out! Friday. I found a puzzle called “Make It Even” in The Moscow Puzzles: 359 Mathematical Recreations by Boris A. Kordemsky. The book is published by Dover, so it’s super affordable!  I’ve found numerous puzzles I want to try out …

## KenKen In The Classroom

How do y’all feel about KenKen puzzles?  Love them?  Good.  Me too. Today I want to post about a program that you may not be aware of.  It’s called KenKen Classroom.  The premise is simple.  Visit the link.  Give them your e-mail.  Then, watch your inbox every Friday for free KenKen puzzles that are formatted …

## International Math Salute

Last week, I attended my first Math Teachers’ Circle meeting of the 2015-2016 school year.  This is my third year to be involved in a circle, and it’s been a ton of fun.  We got to experience spherical geometry using balloons and sharpies, but that’s a post for another day. Today, I want to talk …

## Futoshiki Puzzles

One of the things I love most about the #MTBoS is that for every idea I blog, I seem to get three or more ideas back in return.  Recently, Christine Mishra left a comment on an old post from 2013 with a link to a (new-to-me) logic puzzle: Futoshiki.  Christine thinks these would be awesome …

## Petals Around the Rose

Petals Around the Rose is a fun and frustrating dice-based brainteaser. It makes a great activity for the first week of school in math class! I first learned about Petals Around the Rose from Annie Forest in her blog post on 8 Ideas for the Last Minutes of Math Class.  Usually, I read a post …
