Square Pi Puzzle

I'm currently procrastinating on preparing a presentation I volition live on giving this side past times side Midweek at the Conic Cards), Rebecka Peterson (who never fails to inspire us all amongst her touching One Good Thing posts), Shaun Carter (who used to learn maths inward Commonwealth of Australia earlier he moved to America to hook upwards amongst me) in addition to thence many to a greater extent than amazing Oklahoma math teachers (plus roughly teachers making the trip from nearby states equally well)! 

I volition live on presenting "A Puzzling Classroom" where I volition movement to condense everything I've learned inward the past times 3 years nigh using puzzles inward the math classroom into a 50 infinitesimal presentation field withal leaving fourth dimension for participants to acquire to movement their mitt at a broad diversity of puzzles to acquire a experience for what volition operate inward their ain classroom. Whew. That was likely a run-on sentence, but I'm simply likewise excited to acquire dorsum in addition to edit it down. I'm hoping it volition live on a actually fun, hands-on experience.

Okay. Back to my procrastination. Influenza A virus subtype H5N1 few weeks ago, I stopped past times my classroom to pick upwards roughly puzzles from my filing cabinet to run into what I wanted to role inward my upcoming presentation.


This total box doesn't fifty-fifty include all the novel puzzles I've been creating this summertime that are currently living on our invitee room bed. 


As I started going through my box of puzzles from my classroom, I ran across roughly of my most used puzzles that I decided deserved an update. These were roughly of the real kickoff puzzles I used inward my classroom - long earlier I ever had a puzzle table. Yes, I should likely acquire my presentation written up, but I am likewise eager to percentage roughly of these updated puzzles amongst you. Procrastination past times blogging. It's a existent thing.

The kickoff puzzle I decided to give a "makeover" is a favorite puzzle that I line out every twelvemonth for Pi Day. I originally blogged nigh it here. I refer to it equally the Square Pi Puzzle. I constitute it through the website mathisfun.com

Students are given a purse of 5 pieces. There are 2 split challenges for students to complete. First, students are challenged to combine the 5 pieces to cast a perfect square. Pieces may live on rotated, but they may non live on flipped or overlapped.



This puzzle is tricky, in addition to students oftentimes movement to detect unorthodox solutions.



So unopen yet thence far away!



Once students detect the square, they are in addition to then challenged to rearrange the pieces to create a pi symbol. I've ever had to post service an outline of what the pi symbol should await similar on the dry out erase board otherwise my students volition come upwards up amongst roughly real weird shaped pi symbols equally solutions!



Usually students detect this challenge a fleck easier than the square.



I've ever given the instructions for this puzzle verbally. So, the kickoff affair I decided I needed to practise was type upwards an education sheet. This volition allow me set this puzzle out during my presentation for teachers to tackle on their own, in addition to it volition also allow me the pick to post service it inward my classroom equally a puzzle for students to tackle on their ain instead of alone existence able to role it equally an all-class task. (Plus, students volition right away know precisely what the pi symbol is supposed to await similar now!)


After this was typed upwards in addition to printed, I decided to also create a jumbo version of these pieces that I could set upwards on my dry out erase board amongst magnets equally my puzzle of the calendar week during the calendar week of Pi Day if I don't desire to role it equally a whole-class activity.


You tin download the updated version of this puzzle here. The file includes the education sheet, a page of puzzles that are sized for private pupil use, in addition to a jumbo fix of pieces that could live on used on a large table, the floor, or dry out erase board.
