Octm Recap: Fun Functions

This is my 2d weblog post service recapping sessions Shaun as well as I attended final calendar week at the Oklahoma Council of Teachers of Mathematics Summer Conference.  Be certain to depository fiscal establishment jibe out my previous post service on High Yield Geometry Routines!  

The 2d session nosotros chose was called Fun Functions yesteryear CPM.

The Bug Problem

We began the session yesteryear checking our agreement of what a business office is.  I took a painting exhibit of the PowerPoint slide, but it didn't come upward out readable at all.  So, you'll conduct maintain to pose upward alongside my re-creating the slide inwards Microsoft Paint...

I was shocked at merely how many teachers inwards the room voted that this was most definitely non a function.  Then, I started thinking most what my students would country if I gave them this question.  The regard was non pretty.  My kids postulate to know to a greater extent than most functions than merely the vertical delineate test!  

Function Machines

The laid out activity nosotros did was to guild business office machines.  

Here were our 4 functions:

Of course, they were printed on business office machines as well as laminated for durability.  (And, for the record: laminated papers are actually difficult to photograph inwards a vivid classroom!)  

CPM has posted these business office machines equally a free PDF on their website if you're interested.

Our delineate of piece of occupation was to conform the functions as well as therefore that when a half dozen was dropped inwards the laid out business office machine that the final machine's output would live 11.  This led to roughly skillful conversation inwards our grouping most which functions couldn't live last.  

CPM also has a PDF version of this activity alongside an easier gear upward of functions that I excogitation on using alongside my Algebra 1 students this year.  

Silent Board Game

Next, nosotros moved on to an activity called soundless board game.  

When nosotros entered the room where the session was held, this laminated sail was taped to the wall: 

The regard is that the instructor puts upward an incomplete input/output table.  

Here's the i nosotros used inwards our session:

I got this ikon from page 8 of this file from CPM that features several pre-made Silent Board Game tables. 

As nosotros played the game, I realized it genuinely was a soundless board game.  The facilitator would concord upward her dry out erase marking until someone raised their hand.  Then, she would mitt them the dry out erase marker.  They would walk to the board as well as fill upward inwards an output value.  If the output value was correct, in that location would live silence.  IF the output value was incorrect, in that location would yet live silence.  But, the instructor would walk to the board as well as erase the wrong value.  

This continued until the board was filled.  Then, nosotros moved on as well as silently filled inwards the dominion for the business office as well as the functions' increase rate.

I'm honestly non certain how this activity would play out inwards my classroom.  Would my students remain soundless as well as engaged the entire time???  

One player inwards the session suggested a tweak to this activity: conduct maintain a graph where students plot each indicate later adding it to the table.  This could assistance students meet if the business office was linear, exponential, etc.  

Function Walk

After the Silent Board Game, it was fourth dimension to exit of our seats as well as create a business office walk.  Our facilitator suggested that this was a bully activity to larn students outside.  If doing it outside, she suggested that nosotros could depict the axes of our coordinate plane alongside chalk.  

Since she industrial plant for CPM as well as does this presentation frequently, she had taken 2 rolls of ribbon as well as written the values on them to serve equally axes.  I regard this was quite ingenious!  

We were each given a laminated index bill of fare alongside an input value filled in.  Different people received dissimilar colored index cards.  I was inwards the ruby-red group.    

The purpose of the color-coding became clear when nosotros got our handouts.  As a someone alongside a ruby-red card, I would live helping to graph the equation y = 2x + 1.  

We took turns graphing dissimilar functions.  

Here's my location on the x-axis earlier nosotros moved to our appropriate spots.

And, here's a painting exhibit of the residuum of the ruby-red grouping inwards action:

If I terminate upward pedagogy trig i time to a greater extent than this year, I intend I'd definitely similar to create roughly kinesthetic graphing of trig functions.  

There were several other activities inwards the handout that nosotros didn't larn to.  A re-create of the handout for this presentation tin give the sack live flora here.
