New precalc project... (why do I do this to myself?)


As an end-of-quarter project I'm thinking of assigning something like this.  I'll have the kids take a picture (maybe offer the option of working in pairs, but then they have to do 2) then using Geogebra come up with a equation that fits it.

So for the past 14 hours or so I've been trying to figure out how to use Geogebra.  To say that I'm not fluent with it is a massive understatement.  I figured a couple of things out, but I ended up e-mailing Steve Phelps (a Madeira High School teacher who runs Geogebra workshops) to help me out.  He was amazing.  Within 10 minutes he'd e-mailed me directions to use the regression capability plus two screencasts on how to adjust the picture. 

So I think I have the basic idea of the project down.  Now I'm just trying to figure out how I can get the kids to turn it in.  I'd like a hard copy, but I'd also like an electronic copy so I can put some on the class blog.

And thus begins my new challenge.

Oh, did I mention that I want to give them the assignment on Thursday and have it due sometime next week?  The end of the quarter is next Friday.

A step....

I actually got my 1st period class laughing with (at?) me on Friday.  It was quite an accomplishment. :)  I have to admit that it was me being dumb... but what's new?  We'd been talking about quadratic functions - I gave them f(x) = ax2 + bx + c and asked for it in standard (vertex) form, axis of symmetry, and x-intercepts.  After letting them muddle through the completing the square bit I stepped in to help out.  It's sad how many kids just sat and stared at it... will definitely have to keep this question in mind for the quiz!  It was when we were solving for x-intercepts that the lightbulb finally went off for me - we should end up with the quadratic formula!  How fun!  I guess I was acting kinda dumb about it, but it really got me excited.  They thought it was pretty funny, but then some of the kids actually agreed with me that it was kinda cool.

We're reviewing today in Algebra 2 - I'd planned on giving them a graphing linear equations/inequalities quiz on Friday, but the piecewise functions bit is really tripping some of them up.  Ended up doing an extra day of review on Friday.  I hate Monday quizzes and avoid them if possible, so the quiz is tomorrow instead.  I didn't want to just give them another worksheet today, so I worked yesterday and came up with some review stations (a la @JackieB's post).  If I can, I'd like to split the kids up into groups of 3 making sure that each group has a kid that I know can graph the piecewise functions.... 

Here (box.net link) are the problems I came up with.

A2 Graphing Equations Review Stations                                                                                                                                   

I'm trying to figure out how to get them the answers for each of the problems so they can check their work.  The stations shouldn't take the whole class period, so I may just project the answers after everyone's done.  We'll see.  I'd also thought about getting out the little dry erase boards and having a station where they graph on the board, but I want to be able to see what they've done, too.  Guess I'll stick with the paper.

Homework questions

We had a new arrangement for parent conferences this year.  Usually half of the teachers sit in the cafeteria and half in the media center at individual table,  parents wander around and talk to who they need to talk to.  It can get noisy and there's little privacy.  Also, most of the time is spent on "walk-ins", so you have no idea who is approaching your table.

Yesterday they tried something new.  We were all in our individual rooms and most of our time (4:30 to 7) was appointments only.  The last hour was walk-ins.  I was pretty excited about it because I'm usually not all that busy and have time to get work done.  I thought being in my room would help me get even more work done.

I was wrong about getting work done - I had a pretty constant flow of parents all night on.  I'm not sure if it was due to the new arrangement or what, but I had 7 appointments set up (usually have 1 or 2) and someone always waiting at my door during the last hour for walk-ins.

The good news is that I actually talked to a few parents that I needed to talk to.  Usually it's my Honors Precalc parents whose kids have 95+ .  I saw them, too, but also saw some parents of Algebra 2 kids who are struggling.

One mom really got me thinking.  Her son is a sophomore in Algebra 2 and has a middle B. Not too shabby.  When I looked at the breakdown of his grades, though, it really got me thinking.  His homework average (checked on completion) is a 69%.  There was a week where he didn't do anything.  When you look at his test and quiz averages, though, both are in the 90s (A and A-).

At this point, for this kid, not doing his homework is obviously hurting his grade.  But he's shown on assessments that he knows the material.  In the past I would have said that he's not fulfilling the requirements of the class and his grade is reflecting that.  Now, though, after seeing all this talk on twitter about people not giving points for assignments and grading using sbg, I'm at a point where I'm not sure which way to go. 

I was thinking about this on the way home last night.  Is there a solution?  What if I told the kids that I would drop all of their missing assignments for a chapter if they got an A on the test?  But then what if they don't do anything and fail the test?  What if I don't check homework at all?  Then I'm afraid that so many kids wouldn't even give it a shot - especially the CP and below kids.

What to do, what to do.

The Worst Day Ever

All kinds of stuff happened yesterday... I'm just so glad the day is over!

The good (?) news is that most of it had nothing to do with school.
  1. My little girl got sick at school (well, she had a tummy ache) and I made bunches of phone calls to get people to pick her up and watch her for the afternoon only to hear back from her teacher that she was now feeling fine.  Calls then had to be reversed.
  2. We had conferences at school, so I rushed home to get the kids from the babysitter to take to a friend's only to hear from my husband that he'd gotten off of work early and was just about home.  Basically, I wasted 20 minutes or so in the car.
  3. Made it back to school to find out that I couldn't get logged into my online gradebook. Panic ensued.  Turned out that it wasn't just me, so our assistant principal made some phone calls and got things figured out.  Luckily, I still had time to get some grade reports printed for parents.
  4. Conferences were fine (except for one mom who kept saying that "that one project" in precalc (which I looove) was keeping her son from an A+... said she was "just kidding".... but she kept saying it over and over).  More on conferences later.
  5. Got home around 9:00 to discover my 1st grade son's homework not done and both kids still up -  normal bedtime is 8:00.  I took both kids up to bed while hubby watched tv (!) and got head-butted in the nose by my son who didn't want a bedtime kiss because he was mad that I wouldn't give him any ice cream.  Thought I was going to die.  Ran downstairs crying and let hubby deal with now crying son.
  6. Did I mention that the Reds were no-hit in their first play-off game?  Ouch.  I had the tv on in my classroom (muted)... my principal walked in while I was talking to a parent and turned it off.
Glad that day's over.  Nose still hurts.

Bueller?

I think my first period class hates me.

Ok, this might be a little strong.  But every day I do my little song-and-dance routine and they just sit and stare at me.  No reaction.  You all realize, I hope, that I don't actually sing and dance (usually), but I try and liven things up with jokes and questions and such.  No reaction.  Trying to get answers out of them is like pulling teeth.

I'm trying to attribute it to the fact that it's 7:30 in the morning and they're really not awake yet, but it's starting to get me down.  I also haven't had a first period class for 7 years, so I really don't remember what it's like.  Is it this way everywhere?  Does your school day start so annoyingly early?

(The kids just asked me if I was a former Army sniper because I keep "shooting them down" and spotting their phones.  This is obviously not 1st period.  It's 7th period on Homecoming Friday... crazy time!!)

This makes me realize how much I rely on the kids for input and reaction.  I enjoy being here and being with the kids, but it's gotta be a reciprocal relationship.  I want the kids to have fun and look forward to coming to class.  Not getting any sort of reaction from them bothers me.

Are they learning?  Yep.  Is that enough for me?  It might have to be.
