Bookcase Logic Puzzle from The Big, Big, Big Book of Brainteasers

Today, I'm sharing an awesome logic puzzle that I typed up over a year ago and never got around to using/sharing last year because I could never remember to bring a piece of red cardstock to school with me to print out the pieces. Oops...


This bookcase based logic puzzle is from The Big, Big, Big Book of Brainteasers (affiliate link).


You can still access quite a few of the puzzles for free, though. Amazon's Look Inside Feature lets you look at quite a few of the puzzles for free. Just keep clicking "Surprise Me!" on the left pane to see a different page of puzzles. 

https://amzn.to/2JQpjkp

I printed a bookcase template on 11 x 17 cardstock (affiliate link).


The top is printed with six clues that instruct how the nine items printed on colored paper should be placed.


The clues reference three types of items: flowers, toys, and books. And, it mentions that there are red, blue, and yellow copies of each item.
I created a page of pieces to represent each item, and I printed it three separate times on three different colors of paper (red, blue, and yellow). This makes three separate sets of pieces for solving this puzzle. I would rather end up with extra pieces than waste paper.


If you don't have access to red, yellow, and blue paper, you could easily edit the file to match the colors that you do have access to. 


I combined the fact that all items on the top shelf are red with the fact that the leftmost item on each shelf is a flower to determine that a red flower should be the leftmost item on the top shelf.

Then, I used the clue that the middle shelf holds two yellow items which are not books to place the yellow flower and yellow toy on the middle shelf.


And, I'll leave the rest of the puzzle to you and your students to solve! 

You can download the files for this activity here. If you don't have the ability to print on 11 x 17 paper, I have also uploaded a letter-sized PDF version.

Monday Must Reads: Volume 54

It's Monday, and it was definitely feeling like a Monday this morning. Discouraged by my overwhelming to do list and never enough time to accomplish enough where I feel like I made a dent, I did the natural thing. I turned to twitter. Twitter is full of amazing ideas that only add to this to do list, but more importantly it is a place of encouragement that reminds me why I've dedicated myself to this crazy job of teaching math to high schoolers. The inspiration must have worked because I did end up knocking quite a few things off my to do list by the end of the day.

I thought I should share this inspiration with you in case you too are having a case of the Mondays. Here's my weekly-ish twitter round-up of math teacher awesomeness. I hope you find some inspiration in these posts.
