My Favorite: Coordinate Bird Geoboards

Today, I desire to part my favorite novel way to manage struggling students amongst graphing linear equations.  At the goal of final year, I was asked to render a listing of resources I would similar inward my classroom.  One of the things I asked for was coordinate bird geoboards.  [You tin flame read almost the residual of what I got here.]  I asked for twelve of them, thinking that each couplet of students could share.  Now, I'm regretting that because I wishing I had plenty for every educatee to bring their own.  

These bring been AMAZING.  My kids bring actually enjoyed using them, in addition to and thus many of the problems I've had inward the past times haven't been an effect this year.

Since I started teaching, I bring e'er had a few kids who would "graph" past times plotting the y-intercept in addition to drawing a random employment through it.  Guess what?  You can't create that amongst a geoboard.  You bring to bring at to the lowest degree 2 pegs to brand a employment which agency they HAVE to piece of work the gradient to respect about other point!
I besides used to bring students who would mess upwards on their gradient in addition to non realize it.  For example, they would larn upwards 2 in addition to correct ane at ane betoken instead of upwards iii in addition to correct one.  The employment looks *almost* right, in addition to usually, they would move fine amongst this.  With the condom bands, my kids know that if all the pegs are inward the correct spot, the condom band volition prevarication smoothly.  There bring been in addition to thus many times when a tyke has asked for manage because the way the condom band is laying has told them that something isn't quite correct amongst their graph.

Since the x-axis in addition to y-axis are movable, non all of my kids bring graphs that hold back just the same.  This leads to about awesome conversations that I never had when I but allow my kids graph their lines on the dry out erase boards.  It besides agency my students tin flame graph equations that wouldn't move possible to graph on our dry out erase boards.  I honey watching them motion the x-axis in addition to y-axis every bit they work.  It gives me promise that when they larn to Algebra 2 that changing the window on the graphing estimator won't seem in addition to thus weird.

Now, these boards create introduce a few problems.  You can't graph fractional intercepts.  Instead, nosotros but bring to graph the other points in addition to banking concern jibe that the condom band does cross the axis at the appropriate place.  I warned my kids the commencement hateful solar daytime nosotros used these that the commencement fourth dimension person shot a condom across the room that nosotros would position them up, in addition to I would manus out a bundle of graphing worksheets instead.  This seemed to create the trick.  I never had anyone moving-picture demo a condom band (to my knowledge).  I did larn striking past times a condom band once, but it was a consummate accident.  I bought inexpensive containers (5 for a dollar) at Dollar Tree to shop the condom bands in addition to pegs in.  This helped Influenza A virus subtype H5N1 LOT, but I nevertheless had to selection upwards a lot of bluish pegs out of the floor.
