School School School

Back to school on Monday for the start of PD week. Our fun admin has decided to "flip our lessons" for the week, so that we have more time to chat and plan together. That should be new and intriguing. 

And we have 2.5 new math teachers to show all the ropes to. Yay for new blood and new ideas. Boo for sleep deprivation. Yay for getting back to more people to talk to than just my mirror's image, so I can alleviate the loneliness of summer isolation. Boo for sleep deprivation. Yay for actually moving around to justify eating calories. Yay for goofy kids and spontaneous laughter.

This year (don't have the official word yet, though, you know, since it's more than a handful of days before school starts), I will be teaching Precalculus, AP Calculus AB, Digital Electronics, and Computer Science 1. A nice mix to keep me from getting bored. 

I'm working on doing some form of SBG in DE and CS1. I had grandiose plans of mapping it all out during the summer. Yea, about that ..... apparently, it will be business as usual, and I'll think about to and from work and in between and map it out as the year goes on. I don't know why I'm so continually deluded into thinking that I'm a different person than I really am.

Other than that, hopefully it's another epic year in the making. Good luck and good math to everyone else who is starting or has already started school. Go Us!

In Class 1st Day Activity

Okay, after 17 years of teaching, maybe I WON'T leave everything until the last minute, because I think I've just finished all my 1st day things. Hah! Who am I fooling. This is a fluke. Soon it will be back to business as usual. This year is different, though, because I think I'm going to fly out for the weekend before school starts to see my turning-80-years-old dad, so I won't have those 2 days to get ready.

I did just remake my 1st day in-class activity for precalculus. It really has nothing to do with precal, but that's the class I'll use it in. I like my calculus activity from last year and will do it again, and for digital electronics, I'm going to have them do a DE thing, and for CS, they will be coding independently from day 1.

I was inspired by this activity from KFouss. Woot! Internet Searches! 

Here is my version:





These will be done by the kids in class while I'm snapping pictures and calling roll and passing out a seating chart and passing out more information.

Who Vacuumed Up All the Summer?

Sheesh! I just realized that I only have 2 unstructured-ish weeks left of summer. Must. Soak. Up. Fun.

I did enjoy doing a crafty thing by knitting and felting a "bowl" for a friend (just look away from the glaring error that SOMEONE was too "zen" to fix):


And I have revised my first-day homework assignment:



And I'm trying to sit less by sprinkling exercise in throughout the day via a checklist:


 Other than that ....

Studying Tips for Students

I recently attended a CS workshop for teachers, and if you live in TX, I highly recommend it for next summer. We learned a variety of things, and though some topics were not immediately adaptable to taking back to the classroom, they still were fascinating things you could mention to your students or adapt in some way to your population. Example, did you know that your brain doesn't have to process how to walk (for the most part), the mechanics of the motion are stored in your spinal cord.


One of the talks was on effective teaching, and the presenter mentioned VARK, which I had never heard of. This stands for visual/aural/read-write/kinesthetic, and, of course, refers to learning styles. What I found useful in the talk was actual suggestions on how students could study for and take exams more effectively than they may be doing currently. The hand out was not in a form I would hand out, so I made my own version on half pages for the students to tape in their composition notebooks on the first day of class for future reference. I culled from the VARK website and others that offered tangible ideas.



Online they have a questionnaire for the kids to take to determine which type they are (yay, first night's homework!). I like that you can choose more than one answer for each question and that you could be a "multi-modal" learner. There are different versions of the questionnaire for adults and such (do a search on VARK).


I want the students to tape in ALL four styles into their notebooks because they may find helpful ideas from a mix of strategies.

Geometry Idea

Next year will be the 2nd year in a row I haven't taught geometry, but I had an inkling of an unformed idea for a possible exploratory activity. Whoa! Doesn't that sound like you just want to jump on it and use it the FIRST day of school (far far away from now).

I was in an Airport Shuttle and staring mindlessly out the window and saw a building wall made up of tessellated hexagons. Then I remembered how learned about angle sums of polygons in class by separating various polygons into triangles from one vertex and noticing a pattern [(#vertices - 2)*180]. 

Let's use the pentagon for an example of my future I-can't-use-it idea. Kids most likely don't know that there are 3*180 or 540 total degrees in all the interior angles of a pentagon. I was thinking of (for the pentagon group) having the kids use 10 pieces of spaghetti taped on 5 different scraps of paper to form 5 different angles. Then they would measure the angles and get a total sum of the 5 angles. Then they would try to manipulate the 5 taped down "2 sides and a vertex" scraps of paper to try to form a pentagon. 

I'm thinking there would be 4 or so people in a group, and they would each have a different sum they would most likely come up with. Most likely a pentagon won't be able to be formed unless they happen upon a 540 degree sum.

Then maybe they could try again. Then maybe they could see what works and get that sum (having a human error discussion at some point for measuring mistakes). I'm also thinking there would be different groups with 4 sides and 6 sides (3, too??).  In this way, they can see the tactical things that go wrong with angles that don't "fit". Then there would be a follow up summary and pattern.

Next post: things I could teach in 6th grade math ..... KIDDING

Playing with Math

I just finished a nonfictional Romance Book called "Playing with Math", edited by Sue VanHattum. It's filled with passion (for math), joy (of games and puzzles), good-looking heroes and heroines (math makes you sexy), conflict and tension (hello math haters and standardized tests), and a warm and fuzzy resolution (math conquers all). Okay, it's not really a romance novel, but the passion about math is threaded throughout the whole book. There's basically something for everyone, whether you are a math teacher of any sort, a parent, or a math enthusiast.

I teach in a public school to goofy high school students, so I can only give my perspective as a non-mother, non-math-circle-participant, non-unschooler, non-homeschooler. But just like in math, where you see patterns in one problem and can then extrapolate to solve OTHER problems, in this book, I could read about the variety of settings, and always find something that I can either take back to my classroom or take back to my mind to work on. 

Every other chapter is a math problem of some sort. These range in levels of difficulty and variety of math concepts. Many times I found myself putting the book down and pondering the cool problems and figuring them out. There are also a ton of resources listed, from books, to online options, to people you could e-mail and start a discussion with. This wealth of goodies in itself is a reason to read "Playing with Math".

Before I read this book, I only had my biased, public-school-teacher opinion of homeschooling and had never heard of unschooling. Through the various sections and vignettes shown, my opinions were swayed with an understanding of how such situations could be in the best interest of different students, and how kids could thrive. And even if I won't rush out and un-enroll my non-existent offspring and start unschooling their imaginary selves, I did find myself taking notes on each chapter to remember great quotes and philosophies and teaching techniques that I'd like to remember and adapt to my classroom.

I also enjoyed to peek into things I didn't know existed. There is a section on taking a math circle to a prison, and the nonthreatening and successful way the teachers engaged with the men. There is a section about the nonlinearity of learning math, written in a nonlinear and creative fashion, and it's filled with words I want to mull over and process. And these are just a few examples.

Whether you want to have a new source of good math puzzles, or find out how to start a math circle, or re-engage your love of math, or find more things/thoughts/techniques to bring back to your class this coming fall, or simply to stay awhile in the company of others that love math as much as you do, I think you can't go wrong with this book.

Binary Addition

I would like to move towards SBG for various basic topics in my Digital Electronics class next year. To that end, I will spend this summer creating and/or finding online practice tools for my students to hone their skills. 

One of the topics they learn is Binary Addition. After searching for "just the thing" online and coming up short, I created a Scratch program for them:
 

I think I'll leave it as such, but if you have any suggestions for improvement that can easily be done by a summer teacher, thanks for sharing.

Also, I had originally created this program with Java with the intention of making an applet to put on our school website. This turned out to be a pain full of "security issues" ... "bad!" .... "don't even think you can open or share this applet". Don't know if I'm doing something wrong, or if that's the way of applets these days, and I have to pay money or some such to be able to have that message not come up. Does anyone know?
