How Good Tin Dismiss You Lot Gauge Thirty Seconds?

How good tin you lot gauge thirty seconds?  This is the interrogation I posed to my Algebra 1 students a couplet of weeks agone equally operate of our unit of measurement on information analysis.  

My master copy computer program as well as the computer program I carried out during start catamenia was to projection an online stopwatch on my SMARTBoard.  


I had all of my students unopen their eyes.  I told them the exact 2nd that I pressed "Start" on the timer.  Their task was to opened upward their eyes when they *thought* thirty seconds had passed as well as to tape the amount of fourth dimension that truly passed.  

This would in all likelihood lead keep worked but fine if my students hadn't been as well as then excited past times this activity.  One of my students start hr opened his eyes, saw that he was at precisely thirty seconds, as well as yelled out a cry of glee.  This, of course, caused my other students to opened upward their eyes as well as also accomplish near-perfect results.  Not precisely what I was going for!  

For my 2 afternoon classes, I pulled out my ready of OERB workshop.  I received an additional vi timers from a local donor through the OK Education Needs Facebook group.  


Students were instructed to accept turns estimating thirty seconds inwards PAIRS.  This took a flake to a greater extent than than twice equally long equally doing it equally an entire class, but the information was as well as then much to a greater extent than accurate!  



One pupil would unopen their eyes as well as gauge thirty seconds spell their partner timed how long their gauge truly was.  Then, they would switch.  


Here's the information collection shape I gave students to mucilage inwards their interactive notebooks: 


Silly me gave students a box titled "Your Time." In retrospect, this should lead keep been titled "My Time!"  Earlier inwards this unit, I didn't give students a designated infinite to tape their information value.  This led to lots of confusion later on on.  Lesson learned!  


Another change I demand to brand for adjacent yr is to give students a specified house to write the information inwards order.  I had to mash this in, as well as it would await improve if it had a box of its own.


Students copied downwards the information from the other students inwards their shape equally I recorded it on the SMARTBoard.  We ended upward rounding our times to the nearest 2nd to brand calculations as well as pretty much everything easier!  


After putting our information inwards fellowship (see above!), I had students discovery the 5 release summary, IQR, as well as cheque for outliers.

sixth hr discovered that 49 was an outlier.

For adjacent year, I would add together a interrogation to the bottom that asks if at that topographic point are whatsoever outliers.  When my students took this quiz, many of them struggled when I asked them to write a judgement explaining if at that topographic point were whatsoever outliers.  I demand to brand certain my students are writing downwards a judgement to justify the presence or absence of outliers each fourth dimension nosotros practice!

On the within of our booklet foldable, students were given infinite to brand a box-and-whisker plot, point plot, stem-and-leaf plot, as well as histogram.


See that annoying trouble that the school's re-create machine seat through my page?  My students were truly really excited nigh it because many of them used it to shape the release trouble for their box-and-whisker plot.  In the future, I volition give students a pre-printed release line.  Then, they volition entirely lead keep to produce upward one's heed how to release their release trouble to capture all of the data.  This should salve a flake of precious shape time!


I would render a pre-printed release trouble for the point plot, too.


I intend I mightiness truly lead keep them brand the point plot on top of the release trouble as well as brand the box-and-whisker plot nether the same release line.  I did this alongside a Tenzi (affiliate link) activeness I lead keep all the same to weblog about, as well as it worked pretty well!


Since our information was as well as then unopen together, my students as well as I chose to brand a split upward stem-and-leaf plot.  Originally, I idea my students would survive truly opposed to this change of the stem-and-leaf plot, but they proceed suggesting fourth dimension after fourth dimension that nosotros split upward the stems.  Many of them fifty-fifty chose to split upward the stems on their quizzes!

Next year, I desire to seat some graph newspaper inwards the background to assistance students trouble upward their digits.  This volition also ensure that all of the digits destination upward taking the same amount of space!


Finally, my students made a histogram from our information of estimating thirty seconds.  In the future, I would also seat graph newspaper inwards the background.  This should assistance students brand all of their equivalent towers equivalent heights.
