Training, Fire Drills, Paper Placemats, and Animal Functions … oh my!

22 Sep

By 8 am Friday morning, I thought the day was going to be AWFUL! I had to deal with a bout of tears before school and a student barfing during 1st period. Luckily, the day, and the week now that I reflect, was pretty darn good!

1. Training Pays Off

First period Friday, my Functions/Trig (pre-calc) class was working through problems in prep for Monday’s test. I was AMAZED at how engaged they were … I heard talking about math, I saw students going to other student’s desks to explain. I am a proud momma bird math teacher!

Looking back I realized that I have been setting the stage for the last few weeks. First the classroom is set up in “pods” of 4 all facing the board (need a picture) and I have encouraged the students all year to “work with your group”. WOWZERS! It paid off. I put the solutions on the board and circulated. I did help some students, but I found many going to their groups before raising their hand.

2. Fire Drills Aren’t All that Bad

Since we are required to have a fire drill weekly for the first month of school and monthly thereafter, I took the opportunity this week to use the time to get to chat with a student about their non-math life! It was nice to get to know something personal about one student and their interests – turns out our schools Robotics Club is so popular that they have to limit the membership. So my student, who has been part of this for the last 2 years, was in a tie because it was “selection day”. We talked about the club, its purpose, what they do and why he was interested. Now I want to go to one of their meetings after school to show my interest in that student, and maybe I will find others in my class who share this interest.

3. Paper Placemats

Thursday the hubby came home, asked wha’ts for dinner and decided he wanted to go out. No big deal since I was grading papers until he walked in the door and had not even thought about which dinner from the list I was going to make. So down to our local greek/italian/family restaurant just to find out it was family night with face painting … not good for us for that night. So to other local place we come and they have paper placemats. Well, I was explaining some things that had come up in class, using the placemat as a scratchpad. When our server cleared the table we got into a conversation about high school math. Our server revealed that he was worried when his kids got to high school math because he could not do it. That lead to the rather than say I don’t know how to do ____  change the comment to why don’t we google ____ (or ask the teacher for some sites/resources) and figure it out together!

If I changed one parent from the “I can’t do it therefore  you can’t do it” mindset, I have made progress this week!

4. Animals in the classroom

I realized that some of my Algebra 2/Trig students still don’t understand function notation. So I put the following on the SmartBoard:

AnimalFunctions

(minus the blue mathematical interpretation which came after they solved the problems). Surprisingly, not a single student struggled when I gave them the problems with pictures, but once we change it to letters/letter combinations …. “it’s confusing” “that’s not the same”. Next time I am going to start pictorially and teach them the language of mathematics! Maybe, I’ll do a matching game of some sort where they have to match the pictorial representation to the mathematical representation.

All in all, it was a good week. I learned that training pays off, about a students, and came up with a new approach to teach a (review) topics. Now I am going to trade the school circus for the real one, literally. We are off to the Big Apple Circus today … with clowns and a ringmaster and hopefully lions and tigers and bears, OH MY!

Sudoku as Review

17 Sep

A while ago I came across a Linear Equations Sudoku puzzle at ilovemath.org. While I liked the idea, it just didn’t meet my requirements, so I decided to make my own!

Functions_review_Sudoku

I have given this to all three of my Algebra 2/Trig classes to review for their quiz tomorrow. Students loved it! They worked for the 20+ minutes we had left in class without complaint and without asking about the grade, and would have kept going if time had not run out. I even had a few students ask for more activities like it. Success!

So, how did I do it? I made a 10 x 10 table in Word, set both the column width and row height to .4.  In the first row label each grid R thru Z and the first column A thru I. Now find a Sudoku puzzle blank from a newspaper, book, etc. and fill in the same location. Use those numbers to find problems with that answer.

This format is powerful – you can use it for just about any type of problem, even quadratics – just put the constraint that solutions for the puzzle must be positive zeros 1-9 inclusive. And, with a Sudoku puzzle in just about every newspaper finding a set-up is fairly easy.

Here are my answers, just in case: Functions_review_Sudoku_Answers

Remember, sharing is caring. Enjoy!

This Week’s Eatings

16 Sep

Summer Linguine, Super Natural Everyday, p. 137I have made this before, so I will be making the following adjustments: julienne the zucchini instead of grate and add almonds for texture

Orange Glazed Chicken Skewers, Clean Eating, August/September 2012, p. 75

Lime Seared Haddock, Clean Eating, August/September 2012, p. 76

Butternut Squash Pizza, Vegetarian Times, September 2012, p. 66. Changes will be … increase the amount and saute the spinach, add before cooking, use Naan bread for the crust (I have leftovers from last week), and cook on the grill.

Chimichurri Steak, Clean Eating, August/September 2012, p. 79. Do white potatoes instead of sweet potatoes as the haddock has sweet potatoes with it!

This week my yoga class also begins! Yay! It has been two years since I practiced and I am excited to get back into it. Before my hiatus I had been practicing for over 10 years and was going twice a week! I got frustrated with the class/instructor/ambiance and just quit … should have tried to find a different class/studio.

Hubby and I went to the farm market and grocery store today, so we are all set with ingredients!

The weather looks to be really nice this week (upper 70s, low 80s) so maybe we will get out and walk, but at least our windows are open so we can hear the birds that are visiting our feeders outside the dining room and kitchen windows. I like to work at my dining room table so I can watch the birds! I especially enjoy watching the Chickadees take a bath in the dish of water on the table.

I spent my afternoon writing a quiz for my Functions/Trig quiz next week. I have been modelling some of my problems that we use for in class discussion and homework on the Exeter problems as discussed at Global Math Department.  And I just figured out how to make a link here (big props for someone who does not text and is just learning web 2.0)!
 
The past week was a good, but tiring one. We had Back to School night on Day 3 … so 14 hours at school that day! I love how my room is set up … 7 groups of 4 so the kids are beginning to understand that I want them to talk about math (have to find another desk for one class). I have challenged my Functions/Trig (pre-calc AB) kids with Pythagorean Theorem using quadratics and introduced my Algebra 2/Trig kids to point-slope form (which is SO much easier).
 
Cool opener … I had the kids (on day 1) work in their groups to
1. write the equation of a line given a slope and a point
2. write the equation of a line parallel to (1) through a given point
3. write the equation of a line perpendicular to (1) through a given point
 
While they were working on this, I circulated around the classroom and praised those who were on the right track (and let them know if they were correct) and encouraged those who were lost to talk to the others who were on the right track. After about 10 minutes, I challenged the class and gave whiteboards out to those who wanted it. I had student put up a slope and 3 points on the Smartboard and we raced to write the equations. I won by a landslide each time, but it was a great entry into point-slope form. I then went over the 6 problems with the class. 
 
Not sure why half of this post is italicized, but my attempts to undo it result in nothing! Oh well.

Day 1 … DONE!

4 Sep

Status:

Students … not happy to be back and way too quiet (this will change). Incensed that I actually taught today.

Teacher … tired, sore feet and ready for a good dinner, glass of wine and some quiet time. All in all a good day; only one student who seemingly causes me to worry as he is in 6th period (last of the day) and tried to sleep through class!

On to this week’s challenge:

"Algebra 2 and Precalculus are a hodgepodge of ideas."

As I tell my students Algebra 1 takes all those skills you learn in elementary school and middle school and apply them to three topics (1) writing and solving equations of lines (2) writing and solving equations of quadratics and (3) graphing.

Algebra 2 is the same stuff – we are still writing and solving and graphing – but instead of looking ad nauseum at lines and a little less ad nauseum at quadratics, we are going to spend time writing, solving and graphing many different kinds of problems:

  1. absolute value
  2. piecewise
  3. quadratic
  4. polynomial
  5. rational
  6. radical
  7. exponential
  8. logarithmic

But instead of spending half-a-school-year really exploring and learning these topics like you did in Algebra 1, now you get one-quarter to one-third of a quarter. And, we are going to add a few other topics like sequences and series and statistics.

And, in order to be prepared for the state SOL exam (back acronym, stands for Standards of Learning), you need to complete all of it in three quarters. The SOL is usually taken early during 4th quarter, which leaves 4-6 weeks for “enrichment” exercises.

We shall see if PreCalculus follows similarly as it is my first year teaching it. Stay tuned….
