What Inwards The Footing Is A Polynomial?

My Algebra 1 students are currently working through our unit of measurement on polynomials.  Whenever nosotros get working amongst polynomials, the outset affair my students desire to know is "What is a polynomial?"  I travail to respond that earlier nosotros create anything else inwards the unit.  

The Oklahoma standards don't require that my students live able to form expressions every bit polynomials or non or cite polynomials, but I similar to include these inwards my unit of measurement anyway.  

We began amongst a frayer model most polynomials.  I told students precisely what to write inwards the "Definition" box in addition to the "Characteristics" box.  


After finishing these 2 boxes, nosotros skipped the "Example" in addition to "Non-Example" boxes.  This actually stressed my students out.  But, I assured them that nosotros would come upward dorsum to them.

Last year, I had the thought to brand a polynomial or non carte sort, but I never carried the thought out.  This year, I read my weblog post most lastly year's polynomial unit of measurement in addition to saw my Federal Reserve annotation to myself most making a carte sort.  I wasn't actually inwards the mood to brand a carte sort, in addition to then I decided to plow it into a coloring activity.  Students had to color inwards the boxes that contained polynomials.  If a box did non comprise a polynomial, the students would receive got to write downwards what dominion it broke that kept it from existence a polynomial.


I was a chip tricky amongst around of them.  For example, my students unanimously agreed that x to the iv over 2 ability was non a polynomial because it contained a fractional exponent.  When I told them that it was a polynomial, they were flabbergasted.  Then, I challenged them to figure out why it actually was a polynomial.  After a few moments of critical thinking, ane pupil inwards the course of pedagogy would realize that iv over 2 simplified to only two.  They knew that x squared was a polynomial.


After classifying these 12 every bit examples in addition to non-examples, my students were finally laid to write their ain examples in addition to non-examples on their Frayer model.  I establish that my students came upward amongst much ameliorate examples in addition to non-examples than inwards the by cheers to the intermediate coloring/sorting activity.

Next, nosotros glued inwards a mass that has definitions for the dissimilar parts of a polynomial.  Our re-create machine at schoolhouse likes to set dark streaks on everything.  So frustrating!


Some of the definitions were familiar to students because nosotros receive got been talking most them ALL twelvemonth long.  For example, nosotros learned most damage in addition to coefficients during our rattling outset unit of measurement of the year!


We've too been talking most constants for the entire year.  "Leading term" was a novel vocab give-and-take for my students, though.


Also novel were the damage "leading coefficient" in addition to "degree."


I gave students 2 polynomials to write inwards their notebooks.  They went through each page of the mass in addition to wrote downwards the appropriate facts most the polynomial.  Students had to underline each term, highlight each coefficient, in addition to circle each constant.  Then, they had to write downwards the set out of terms, the leading term, the leading coefficient, in addition to the score of each polynomial.


Now that nosotros receive got reviewed what damage are in addition to learned what score means, that way it's fourth dimension to cite polynomials!


As nosotros were filling out this nautical chart inwards our interactive notebooks, I was cry for students to predict what would become inwards surely boxes.  One pupil started sharing answers which shocked the ENTIRE class.  They couldn't figure out how he already knew these weird words.

It turns out he had noticed the "Naming Polynomials" poster I had created in addition to hung on the wall.  So, he already had the ENTIRE canvass of notes filled out.  The file for this poster is uploaded here.


I am pretty pleased amongst how this naming polynomials practise canvass I made for their interactive notebooks turned out!

Many of my students adopted this same format when naming the polynomials on their quizzes.


I cry back that the procedure of writing out the score in addition to the set out of damage every bit good every bit the cite of the polynomial helped my students to brand to a greater extent than feel of what nosotros were doing.  In the past, I receive got only had them write the cite without the intermediate step.



After nosotros goodness naming polynomials inwards our notes, nosotros did a favorite activity of mine: naming polynomials speed dating.


I haven't turned this activity into a shareable digital file yet, but I definitely should create that inwards the future!  Right now, I'm only using index cards amongst polynomials written on the front end in addition to names written on the back.


My Algebra 1 classes this twelvemonth are quite a chip larger than my classes inwards the past, in addition to then I had to write upward a bunch of novel index cards this year.



I compass each pupil an index carte amongst the polynomial facing up.  I instruct them to figure out the cite of their polynomial.  When they receive got it figured out, they may flip over the carte in addition to cheque their answer.

Then, I instructed each pupil to stand upward up.  Here's where the "speed dating" comes in.  Students couplet up.  Each mortal holds their index carte in addition to then the polynomial is facing their partner in addition to the respond is facing them.  Students accept turns quizzing in addition to coaching their partners.  When both polynomials receive got been named correctly, students switch cards in addition to detect a novel partner.  The goal is to practise naming every bit many polynomials inwards every bit brusk a fourth dimension every bit possible

It tin live a chip chaotic, but the classroom is total of kids talking most math.  So, I couldn't live whatever happier than that!  Here's a few pictures of my students.  I had to block out the faces which made me distressing because they ever expect in addition to then happy when doing this type of activity!
