## 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 …

## Likes and Dislikes Brainteaser

Back in August, a sixth grade girl who attends my church presented me with a brain teaser that her teacher had shared with her class.  Since Thursdays in my classroom start off with a brain teaser, I decided to share this brain teaser with my students.  It’s the type of brain teaser that is EXTREMELY …

## Hashi Puzzles

One of the things I’ve most liked about introducing my students to new logic puzzles is that they’ve been new to me as well!  I was initially hesitant to try the hashiwokakero puzzles with my students because they sounded scary.  I learned about these puzzles from reading the slides from Jeffrey Wanko’s NCTM presentation.  You …

## 5 Piece Square Puzzle Challenge

This 5 piece square puzzle made the perfect challenge to give to my math students for Brain Teaser Thursday. It has been a lot harder than I anticipated to come up with a different brain teaser for every Thursday. Now, I love brain teasers, but there’s a definite difference between the brain teasers I find …

## Shikaku Puzzles

What are Shikaku Puzzles? Shikaku Puzzles are a geometric-based logic puzzle from Japan. I was first introduced to them from a tweet from Bowen Kerins. The goal of a shikaku puzzle is to subdivide the grid into rectangles (and squares) so that the number in each rectangle refers to the area of that rectangle. Only …

## Nonogram Puzzles

I heart logic puzzles.  Give me a long road trip where I’m not the one driving, and I’ll probably be doing one of two things when I’m awake: reading or working logic puzzles. One of my favorite logic puzzles is one I learned about in high school.  My high school calculus teacher would leave us …

## Four Fours Challenge Activity

I recently gave this four fours challenge activity during the last few weeks of the school year. We got off to a rough start, but it ended up being a super engaging and enjoyable math puzzle! My students took their end-of-instruction exam on April 13th.  That was two weeks ago, and we still have three …
