Who Killed Mr. Xavier Pression?

I just got back from AMLE 2016, and what an amazing experience.  I met some amazing people, including many that I've been talking to during #MSCHAT and #TLAP talks.  I know many of you want to hear all about it, but honestly this graphic kind of explains where I am currently at:

I think I need to install some new RAM.

So for now you'll have to read about my latest activity.  

This year my 7th grade math class has been immersed in a game world.  They are in guilds named after mathematicians (Kepler, Nother, Euler, and Brahmagupta), exploring a world, and helping to bring together two nations.  They were introduced to Mr. Xavier Pression, the main diplomat brokering the truce between the nations of Gunthar and Sancrist.  Last week they received a message that Mr. Pression has gone missing.  They completed a series of quests to find him, which all four guilds did successfully.  

Unfortunately at the end of the last quest they found this on the screen at the end of the period:

It took a minute, but they eventually got the pun.

There was shock on everyone's face.  He was dead? How could that be?  They did everything they could to find him.  The next morning they walked in determined to find his killer.  

I purchased this activity from Teachers Pay Teachers.  It is a clue-based activity to have students write algebraic sentences as expressions.  In fact the whole game is set up like the boardgame Clue.  Here is the link to the product - I highly recommend it: Who Killed Mr. X. Pression

Now here is where Dave Burgess would say it is time to kick it up a notch.  They could have just come in and done the activity. I could have had the worksheets with the clues out and they could have just completed them and discovered the person, place, and thing.  However, this was a murder mystery. This was drama.  This was a crime investigation.  So instead of coming in to a worksheet laden room, they came in to this:

SO much positive feedback about the atmosphere.

Dark room, chilling music, the only thing out was the title.  By the way, students were actually working when I shot this video - that's the murmuring you hear in the background.  There was so much excitement and chatter.  They wanted to finish this assignment.  They learned that their sponsors were offering rewards including kingdom points, renown points, and new items to anyone that correctly completes the problems and solves the mystery.  They begged to get it started. 

How often can you say that has happened while teaching writing algebraic expressions?  

Today I will read your future minds...

A few weeks ago my math class started algebra concepts.   I have a fantastic lesson that I spiced up thanks from some advice from Dave Burgess and his excellent seminar on how to Teach Like a Pirate.    Students sit down, get out their notebook, look up and read the board.  However, instead of the usual warm up or friendly message, they see :  "Today I will read your future mind!"

They giggle as usual, and taunt my talents.  I play along - "Oh, doubters... just wait.  You don't even know what you are thinking yet... but I do...."

With that I take out an index card and turn my back to the class.  I look over my shoulder a few times, making sure to have direct eye contact with a few of them.   As I'm turned I write a message on the index card.  I put this index card into an envelope, seal it, walk up to one student very deliberately, and put it into the student's binder, folder, or book, warning all of them not to even touch the envelope.  I then explain how soon they will all write what I have just written on this card.

Hook?  Check.

I then lead them through the typical pick-a-number scheme where you add, multiply, and do all this magic to the number.   I encourage them to choose a lower number as there is some arithmetic to do to this number, but really any number will work.  No calculators are allowed and students must show their work for each step.

Here is the algorithm I lead them through.  I haven't tried reading minds over the realm of the internet, but I'm willing to have a go.  All of you readers, math geeks and non, should play along.  I'm curious if I can use my psychic powers through wifi.  Here are the steps I give my students:

• No talking from here out - it disrupts the psychic energy.
  
• pick a number 
• double that number
• add 4 to the result
• triple that result 
• subtract 6 
• divide by 6 
• add 4 
• subtract the original number from this result (this step usually takes some clarifying)
• circle this final answer

Now I want you to look at this chart.  Find the letter that corresponds to the final answer circled on your paper and write that letter on your paper.

For instance, if you got a 8, you'd choose 'h'

I always make sure to walk around the room to see what number is circled and to clarify this step.  I also help students that may have made a mistake in arithmetic.

Once everyone has their letter I stop and build the drama a bit more.  I close my eyes - pretend to meditate... whatever. Get a good psychic vibe in that room!

When I continue I ask them to think of an animal that starts with the letter they have written down and have them write this animal in their notebook (telling them specifically that spelling doesn't count.)  For example, a student that gets an 8 could write 'hyena'.

I then ask them to think of a color that animal can be, and to write that as well.  For instance, if they got an 8 they might choose a brown hyena, but can't pick a pink hyena.

At this point I walk back to the student that has the envelope.  I look at the answer in their notebook and smile.  I ask them if they think I have the same thing written on the card in the envelope.  They always hesitate.  The anticipation is thrilling.  I ask that student to open the envelope and to read out loud what is written.

Most of the time they don't even read it out loud.  Most of the time they shout out "NO WAY!"  Generally what happens from there is the rest of the class reacts with shock and awe with a hint of fear.  Eventually the card gets read.  Students are in disbelief.  How is this possible?  Will you teach me?  PLEASE? TELL ME YOUR SECRET (seriously - students begging to be taught?)  Nobody can believe that I have done the impossible.  Same color. Same animal... well, 95% of the time.

If you are playing along you might wonder what is on in that envelope and if I've read your mind through the world of cyberspace.

You may wonder, if in fact, I will end this post with the words grey elephant.  

I think I will.

Next time I'm using one of these as a prop.
